What Do I Need To Know About Today's Automatic Transaxles And Transmissions?

Today’s car and truck automatic transmissions are the most complicated and least understood major component. In later model car and truck transmissions use a combination of sophisticated hydraulics and computer controlled parts and components. Front wheel drive automatic transmission car and trucks incorporate the third major component the differential. Front wheel drive automatic transmissions are known as transaxles. The differential or final drive is incorporated in the body of the automatic transmission itself. Front wheel drive automatic transmissions configuration is efficient in terms of fuel economy, handling and manufacturing costs, however, with the additional parts and components housed within the transaxle unit, when it fails, it is generally more expensive to repair. An automatic transmission / transaxle properly rebuilt can deliver longevity equal to or in excess of your car or trucks original transmission / transaxle.

For cars and trucks used in severe driving conditions, there are additional precautions which can be taken to insure against premature transmission / transaxle failure and make a car or truck better able to deliver the performance the driver wants in these unusual driving conditions. Some severe driving conditions include heavy city, stop and go driving, regular mountainous driving, pulling heavy loads, unusually warm climate, and trailer towing. Under these severe conditions it may be advisable to install a transmission external cooler or updated valve body shift kit.

If you subject your car or truck to these types of driving conditions, please feel free to contact the transmission specialist at Sergeant Clutch Discount Transmission & Automotive, they will be pleased to make the appropriate recommendations to insure that your car or trucks automatic transmission / transaxle meets all your needs and wants.

What Are Normal Driving Conditions For An Automatic Transmission?

Car and trucks that are usually driven occasionally or for short distance trips are often subjected to unusual wear and strain to the automatic transmission. Not only do driving conditions affect the automatic transmission but the brakes, engine, etc. Cars and trucks that are consistently driven short distances never have the opportunity for the engine to warm up to normal operating temperature. This can cause excessive wear on the engine. Low mileage automatic transmissions subjected to city driving or stop and go driving usually experience far more wear than automatic transmissions with the same number of highway miles. The highway mileage doesn’t create as much wear and tear on the automatic transmission. Highway miles are easier on the automatic transmission as the number of times the automatic transmission shifts up and down through its gear ranges is far less then stop and go driving.

Some other seemingly normal driving conditions can affect the automatic transmissions life span. Conditions such as extreme hot or cold temperatures, snowy roads, icy roads, mountainous terrain, dusty terrain and poor air quality can drastically affect the life of the automatic transmission.

Under normal driving conditions, automobile manufacturers recommend servicing the automatic transmission fluid as seldom as every 20,000 to 100,000 miles. But the question is what constitutes normal driving conditions?

According to most automobile manufactures normal driving conditions of automatic transmissions can range, but most agree that the following conditions are considered normal. Driving about 12,000 to 15,000 miles per year. Keeping the engine and transmission operating at normal operating temperature most of the time. A driving mix of about 1/3 city driving and 2/3 highway driving. Outside temperature usually moderate; not too hot or too cold. Roadways dry, straight, occasional, moderate hills or valleys. Air quality moderate and clean. No excessive speeding, drag racing, jackrabbit starts, hard braking or quick shifting. Light to moderate loads; one or two passengers, with very little weight added to the trunk or cargo space. Tire pressures set properly and all fluids at correct levels and condition.

If you operate your automobile under more extreme driving conditions as most people do you’ll want to reduce the time and mileage between automatic transmission fluid change maintenance services. Having your automatic transmission serviced once a year, or at very least every other year, seems to be the consensus among transmission repair professionals. Under the most extreme driving conditions, it is advisable to install an external transmission filter and external transmission cooler for additional protection.

If you’re not sure when the last time your automatic transmission fluid was changed, just bring your car or truck into Sergeant Clutch Discount Transmission & Automotive in San Antonio, TX for a Free Transmission Fluid Evaluation and FREE Transmission Performance Check.

What Winter Hazards Affect My Automatic Transmission?

Winter conditions vary geographically, but there are a few conditions that are common to most of the United States during the winter months. How you deal with those winter conditions can have a dramatic effect on your automatic transmission. Cold temperatures means cold weather and as temperatures drop, automatic transmission fluid thickens reducing their ability to lubricate. In most of the United States you can deal with this simply by warm up your car or truck for 5 to 10 minutes depending how cold it is. Also driving slowly for the first few miles until the engine and transmission reach normal operating temperature. Automatic transmission fluid doesn’t start flowing through the transmission cooler lines until you put the transmission shifter into drive.

If the temperature tends to get really cold in your area, invest in an engine heater that plugs into a wall outlet and warms the engine before you come out in the morning. A timer will allow you to start the engine warming a few hours before you’re ready to leave and saving you money. For much of the country driving on snow and ice is part of a normal winter.

But there are specific hazards to your automatic transmission on those roadways. One that you may not be familiar with is what can happen if you get stuck. Too often drivers spin their wheels in the hopes of freeing themselves from a snow drift or icy patch. This can cause major damage to the transmission. Today’s automobile uses a computer to control automatic transmission operation. When you spin the wheels the computer sees the vehicle speed rising; in many cases it has no way of knowing that you aren’t really moving. When the speedometer registers 40-or-so MPH, the computer sees the speed, and identifies driving conditions as being right to engage the converter clutch. Now the engine is locked directly to the drive wheels. If the wheels regain traction, their speed will drop suddenly. The result can be catastrophic to the automatic transmission. The best way to get out of a drift or icy patch is to rock the car back and forth, forward and reverse until you can get moving again. Or, better yet, get someone to push or pull you out of the snow. Avoid spinning the wheels, or you could end up damaging the automatic transmission.

No major component of your vehicle can survive indefinitely with water in its internal components. But no other component can be damaged as quickly as your automatic transmission can by water. Even a small amount of water in an automatic transmission almost always results in serious failure and major repair bills. The reason is the band and clutch linings are hygroscopic; that is, they absorb water, even if they have to push transmission fluid out of the linings to do it. This water quickly finds its way down to the metal backings, causing them to rust and lift the linings off of the clutches and bands. The result is metal to metal contact, which always means serious damage to the transmission. To avoid this type of trouble, steer clear of deep puddles. Should you find your automobile submerged, don’t start the engine. Your only chance of avoiding a big repair bill is to have your automobile towed into a transmission repair shop and have all the transmission drained out or flushed out immediately. If you're lucky, draining and servicing the transmission fluid and filter may be all that’s necessary to save it. If not, your auto insurance may cover part or all of the damage. Sergeant Clutch Discount Transmission & Automotive will be happy to supply the necessary technical information to your insurance company.

So whether it’s snow and ice, water, or just plain cold out, winter delivers a whole new set of conditions just waiting to damage your automatic transmission.

Which Transmission Is More Energy Efficient An Automatic Or Manual?

Hydraulic automatic transmissions are almost always less energy efficient than manual transmissions due mainly to viscous and pumping losses; both in the torque converter and the hydraulic actuators. A relatively small amount of energy is required to pressurize the hydraulic control system, which uses fluid pressure to determine the correct shifting patterns and operate the various automatic clutch mechanisms.

Manual transmissions use a mechanical clutch to transmit torque, rather than a torque converter, thus avoiding the primary source of loss in an automatic transmission. Manual transmissions also avoid the power requirement of the hydraulic control system, by relying on the human muscle power of the vehicle operator to disengage the clutch and actuate the gear levers, and the mental power of the operator to make appropriate gear ratio selections. Thus the manual transmission requires very little engine power to function, with the main power consumption due to drag from the gear train being immersed in the lubricating oil of the gearbox.

The energy efficiency of automatic transmission has increased with the introduction of the torque converter lock-up clutch, which practically eliminates fluid losses when engaged. Modern automatic transmission also minimize energy usage and complexity, by minimizing the amount of shifting logic that is done hydraulically. Typically, control of the transmission has been transferred to computerized control systems which do not use fluid pressure for shift logic or actuation of clutching mechanisms.

The on road acceleration of an automatic transmission can occasionally exceed that of an otherwise identical vehicle equipped with a manual transmission in turbocharged diesel applications. Turbo-boost is normally lost between gear changes in a manual whereas in an automatic the accelerator pedal can remain fully depressed. This however is still largely dependent upon the number and optimal spacing of gear ratios for each unit, and whether or not the elimination of spool down / accelerator lift off represent a significant enough gain to counter the slightly higher power consumption of the automatic transmission itself.

What Is Automatic Transmission Fluid (ATF)?

Automatic transmission fluid is a hydraulic and lubricating oil. This component of the automatic transmission provides lubrication, corrosion prevention, and a hydraulic medium to convey mechanical power. Primarily made from refined petroleum and processed to provide properties that promote smooth power automatic transmission and increase service life, the automatic transmission fluid is one of the few parts of the automatic transmission that needs routine service as the vehicle ages. Sergeant Clutch recommends changing the automatic transmission fluid every 12,000 miles or ever 12 months.

What Are The Different Automatic Transmission Fluid Types?

Here’s a list of the different types of automatic transmission fluids and the basic differences between them:

1. Type F Automatic Transmission Fluid: Almost no automatic transmission uses Type F anymore. Type F was designed for Ford transmissions that used bronze clutches. The last automatic transmission made with bronze clutches was the Cruiseomatic, last used in the early ‘70s. Unless you’re talking about a classic car or an antique, you can be pretty sure your automatic transmission doesn’t use Type F.

2. Dexron III / Mercon Automatic Transmission Fluid: This is one of the most common automatic transmission fluids on the market. Most GM transmissions and Ford transmissions, as well as many import transmissions, use this type of ATF. If your vehicles owners manual recommends any form of Dexron or Mercon other than Mercon V this is the transmission fluid you want to use.

3. HFM-Style Automatic Transmission Fluids: HFM stands for Highly Friction Modified; it’s an automatic transmission fluid that provides different friction characteristics than Dexron III / Mercon. This transmission fluid appears under a number of different names, including Chrysler’s ATF+ also called 7670. Many other manufacturers use HFM ATF these include: Honda Transmissions, Acura Transmissions, Jeep Transmissions, Eagle Transmissions. Hyundai Transmissions, Toyota Transmissions, Lexus Transmissions, Saturn Transmissions and Sterling Transmissions.

Are HFM fluids interchangeable? They should be. But to be safe, always use the specific transmission fluid the vehicles manufacturer calls for.

4. Automatic Synthetic Transmission Fluids: A number of automobile manufacturers have begun to discontinue the use of organically based transmission fluids in favor of synthetic transmission fluids. Preliminary tests have shown that most synthetics have similar friction modification characteristics to Dexron III/Mercon transmission fluid, but with improved resistance to heat, cold, oxidation, sheer and synthetic fluid last longer.

Automatic synthetic transmission fluid is one reason why many automobile manufacturers begin to eliminate the automatic transmission dipstick. Manufacturers feel synthetic transmission fluid will last longer, so there’s no reason to let people interfere with the automatic transmission and its operation.

Caution Ford labels their automatic synthetic transmission fluid as Mercon V, which can be a bit confusing. If the vehicles owner manual says Mercon V, it’s calling for the synthetic transmission fluid. If the name is Mercon without the V, that’s the regular Dexron III / Mercon transmission fluid.

What Type of Automatic Transmission Fluid Should I Use?

Automatic transmissions use a special type of oil, called Automatic Transmission Fluid, or ATF. This fluid has a number of duties in the automatic transmission, including lubrication, cooling and clutch application. Automatic transmission fluid provides the connection between the engine and transmission, through a hydraulic coupling called a torque converter. And, when squeezed between the clutches, automatic transmission fluid acts as a “glue,” providing additional friction and holding capacity to drive the car or truck. So automatic transmission fluid is a very versatile fluid. That’s why maintaining the transmission fluid can be so critical to an automatic transmission life.

Just a few years ago there were only two types of automatic transmission fluid on the market Type A and Type F. Conventional wisdom said that Type F transmission fluid was for all Ford transmissions and Type A was for all other transmissions. Conventional wisdom wasn’t all that accurate even back then. These days there are four main types of automatic transmission fluids on the market. And there are dozens of brands and styles to choose from. There are many different types of transmission fluid on the market, and using the wrong type can affect your automatic transmission’s performance and longevity.

So how do you know what type of transmission fluid your car or truck uses? The easiest way to make sure you’re using the right type of automatic transmission fluid is to check the vehicles owner’s manual. It’ll tell you exactly which Transmission Fluid the manufacturer recommends for your car or truck. May times on the transmission dipstick will indicate what type of ATF to use.

What Are 4 Basic Transmission Fluid Conditions?

1. Clean, Clear Fluid, with Virtually No Odor: The transmission fluid is like new. Chances are the automatic transmission’s working fine. Use the vehicle mileage or time since it was last serviced to determine whether you should have the transmission serviced.

2. Slight Brownish Tint, with a Lightly Burnt Odor: The transmission fluid is beginning to burn, and is probably due for a transmission fluid service. If you didn’t have the transmission fluid flushed completely the last time you had the transmission serviced, you may just be looking at the old transmission fluid that was left in the transmission. As long as the transmission seems to be working okay, consider a complete transmission fluid flush service in the not-too-distant future.

3. Brown Color, with a Distinctly Burnt or Varnished Odor: The transmission fluid is burnt, and you may already be experiencing transmission operating problems. If the transmission seems to be operating okay, you might still get away with a complete fluid flush service and transmission filter replacement. But there’s little doubt that the transmission is beginning to wear, so the best you can expect from a transmission fluid service is to buy some time. Eventually you’ll be facing a transmission repair job.

4. Black Color, with a Stench that Will Make Your Toes Curl: The transmission fluid is severely burnt, and the transmission probably is, too. You’re probably experiencing a serious transmission problem. A transmission fluid service at this point will usually be a complete waste of money; the transmission is going to need a major overhaul or rebuild. And there’s the possibility of related problems, such as a clogged transmission cooler or a cooling system problem. Make sure you have these systems checked at the same time, to avoid a second transmission failure.

Of course transmission fluid condition isn’t the only thing mechanics check when examining a transmission’s condition. They also look at operating condition, computer system codes, and any loose material in the pan, to name just a few. Automatic transmission fluid condition is just one of a series of signs used to diagnose transmission problems.

If you’re unsure of whether your automatic transmission fluid indicates a problem, stop by Sergeant Clutch Discount Transmission & Automotive at 6557 Walzem Road in San Antonio, Texas 78239 or call us.

How Do I Check The Automatic Transmission Fluid Level?

Automatic transmissions operate on oil, properly called automatic transmission fluid, or ATF for short. Low transmission fluid levels can have a disastrous effect on the automatic transmission operation. In recent years many automobile manufacturers have started to eliminate the automatic transmission fluid dipstick. These transmissions are called sealed units. Automatic transmissions that are considered sealed units require a much more involved process to check the automatic transmission fluid level. The process of checking the transmission fluid level in a sealed transmission often involves computer diagnostic testing. This puts checking the automatic transmission fluid level beyond the capabilities of the average car driver. If your car or truck transmission doesn’t have a dipstick, you should bring your vehicle by Sergeant Clutch Discount Transmission & Automotive for a FREE Transmission Fluid Level Check.

The best time to have the transmission fluid level checked is at every motor oil change. However if your vehicle doesn’t have a transmission dipstick, you should at least check the transmission fluid level every other motor oil change. The vehicles owners manual should provide a detailed procedure for checking the automatic transmission fluid level.

Sergeant Clutch 12 Step Procedure To Check Your Automatic Transmission Fluid Level

1. Make sure your automobile is on level ground.

2. Start the engine and leave running.

3. Bring the engine and transmission to normal operating temperature.

4. Hold your foot on the brake, and work the transmission shifter slowly through all the gears.

5. Put the transmission shifter back into park.

6. Set the parking brake.

7. Carefully open and secure the hood.

8. Locate the transmission dipstick the vehicles owners manual should show where the transmission dipstick is located.

9. Remove the transmission dipstick and wipe it off with a clean rag or paper towel.

10. Replace the transmission dipstick all the way back down into the transmission fill tube.

11. Pull the transmission dipstick back out and check the transmission fluid level against the markings on the end of the dipstick.

12. If the transmission fluid level is below the full line on the dipstick add the necessary transmission fluid.

Important Note: Always use the recommended transmission fluid by the manufacturer.

If the transmission requires more than a quart of fluid or is using transmission fluid regularly, take your vehicle in to have the transmission checked for leaks. Front wheel drive transmissions usually have the dipstick on the driver’s side of the vehicle, on either side of the transmission. Rear wheel drive transmissions usually have the dipstick on the passenger’s side of the engine compartment near the back of the engine. Checking the automatic transmission fluid level requires working under the hood of your vehicle with the engine is running. Checking the transmission fluid can be very dangerous if you aren’t sure what you’re doing. Use caution and watch out for moving parts and components such as fan blades, fan belts, pulleys, etc.

Do Automatic Transmission Fluid Additives Really Work?

Any auto parts store will have an isle dedicated to automatic transmission fluid additives and transmission fix in a can you can imagine. These products have labels that offer promises from simply making your transmission last longer, stop leak and all the way up to a transmission rebuild in a can. Many of these products don’t work. However there are a few products that really do work. These products usually won’t be at your local auto parts store. Many professional auto repair and transmission shops have access to these products. The professional products offered by professional transmission repair shops tend to make more realistic claims, such as neutralize acids that build up in the transmission fluid, provide additional resistance to the effects of heat, prevent or reverse fluid oxidation, prevent or reverse fluid sheer, modify friction characteristics to improve transmission performance, provide additional lubrication to moving parts, soften and remove varnish from internal transmission parts and components. These transmission fluid additives have the advantage of being able to deliver on their promises.

In today’s transmission industry there are many different types of automatic transmission fluid (ATF) on the market. Several aftermarket chemical companies have come up with a formula to save auto repair shops and automobile owners money. These companies have developed special additives that mix with standard Dexron III transmission fluid and Mercon transmission fluid, to alter the friction characteristics to match special OEM type fluids. One of the most common of these special additives is the HFM additive. When HFM is added to Dexron III transmission fluid or Mercon transmission fluid, it alters the friction characteristics enough to allow it to be used in any transmission that requires HFM fluids.

If you have your automatic transmission rebuilt or the automatic transmission fluid replaced, the auto repair shop may use Dexron III transmission fluid or Mercon transmission fluid along with one of the HFM additives. That’s okay; these transmission fluid additives work great for altering the transmission fluid’s friction characteristics. However, if your transmission is still within its factory warranty, check with the dealer or a factory representative before allowing anything in your transmission besides the factory recommended automatic transmission fluid (ATF). Certain transmission fluid additives or oils could affect your factory warranty.

Sergeant Clutch Discount Transmission & Automotive has a selection of great working transmission fluid additives available. So please do not waste your money on transmission fluid additives and transmission fix in a can that claim to offer a “new transmission in a can.” Check with Sergeant Clutch for information on transmission fluid additives that really work as advertised.

Will Servicing My Automatic Transmission Help It Last Longer?

Yes servicing your car or trucks automatic transmission regularly can dramatically extend its life and enhance it performance. That’s because the automatic transmission fluid or ATF does more than just lubricate and cool the transmission: It also helps drive it. Damage to the automatic transmission fluid, such as oxidation and shear, will reduce the transmissions holding power and life. Old worn out transmission fluid allows the automatic transmission to slip, overheat and can quickly cause it to fail. To keep your automatic transmission working longer, you should have it serviced regularly. A complete transmission service should include: removing and examining the transmission oil pan (where possible), replacing or cleaning the transmission screen or filter, cleaning the transmission oil pan, reinstalling the transmission oil pan with a new pan gasket, pumping out the rest of the old transmission fluid and replacing it with new, high quality ATF, adding a friction modifier or transmission fluid additive package.

Regular transmission fluid services will add miles and years to your automatic transmission’s life. Adding an external transmission filter to the cooler line to remove any dirt particles that make it past the internal filter is a great investment, Also adding an external transmission cooler has many benefits. A complete transmission filter and fluid exchange service, performed annually, can add years to your automatic transmission’s life.

Did You Know Changing Your Automatic Transmission Fluid Saves You Time & Money?

Today’s automatic transmission fluid is much more complex and high tech. Automatic transmission fluid is more than just a lubricate. Transmission fluid helps the automatic transmission move and operate properly. Any wear or damage to the automatic transmission fluid, such as oxidation will reduce the transmissions holding power, creating transmission shifting problems, transmission overheating, and internal transmission part failure. By regularly changing the automatic transmission fluid in you car or truck will dramatically extend the life of your automatic transmission. A simple transmission fluid change or transmission fluid flush annually can add many years to the life of your car or trucks transmission. Sergeant Clutch Discount Transmission & Automotive offers several transmission preventive maintenance services.

Should I Flush My Transmission Fluid?

Sergeant Clutch Discount Transmission & Automotive recommends an automatic transmission fluid service every 12 months or 12,000 miles. This means changing the automatic transmission fluid and inspecting transmission filer, transmission pan gasket and other transmission seals and gaskets for leaks. It is important that you maintain the automatic transmission early on in the life of the car or truck. If not you could set yourself up for real trouble if you change the automatic transmission fluid later on In the automobiles life. Regular servicing of the automatic transmission can provide longer life expectancy, smoother shifting, and increased performance.

How often should the automatic transmission fluid be flushed is a different service from a transmission fluid change. An automatic transmission flush service actually removes all the transmission including the fluid from the torque converter. Flushing the automatic transmission requires a special machine that acts like a blood transfusion machine. It pumps out the old transmission fluid, then pumps new transmission fluid back into the transmission. An automatic transmission fluid flush removes more of the old dirty transmission fluid than the conventional method of removing the transmission pan, draining the transmission fluid and replacing the transmission filter. The automatic transmission specialist Sergeant Clutch strongly recommends changing the automatic transmission filter. The automatic transmission filter plays a big role in the automatic transmission operation. Metal and plastic debris in the transmission fluid become lodged in the transmission filter. This can compacted the filter to the point that it restricts transmission fluid flow. If the automatic transmission fluid has become contaminated with water or some other foreign liquid, then a transmission flush is highly recommend.

If your car or truck has high mileage such as 100,000 miles and the automatic transmission fluid has not been maintained its not recommend to replace the transmission fluid and transmission filter. The transmission fluid that has been in the automatic transmission all these years and miles has become dirty, gritty and broken down. This gritty transmission fluid is actually providing much needed friction for the worn internal parts of the automatic transmission. The old transmission fluid is gritty due to metal shavings caused by normal internal wear and tear on the transmission clutches and acts like liquid sandpaper. This "sandpaper" produces the friction needed for the transmission shift.

Changing the automatic transmission fluid and replacing the transmission filter would remove this friction that the internal transmission parts have become dependent on as the clutches inside the transmission have nothing to grab on to. Flushing your automatic transmission fluid is vital to the overall transmission performance and life. But you must flush it regularly, once the transmission fluid is damaged and burnt, it is sometimes best not to flush the automatic transmission. If you have not been regularly maintaining the automatic transmission throughout the life of the vehicle, you might actually be doing more harm than good if you replace the automatic transmission fluid at this point. For example, putting new clean transmission fluid in an older high mileage vehicle could cause the transmission to slip.

If you are not experiencing a transmission problem and have over 80,000 miles on your car or truck, and have not kept up regular maintenance on the transmission, you have a professional transmission mechanic evaluate your transmission situation first.

Sergeant Clutch Discount Transmission & Automotive has the answers to all your automatic transmission problems.

What Type of Repair Shop Should I Have Change My Automatic Transmission Fluid?

When it comes to automatic transmission fluid maintenance the market is saturated with competition from lube shops, automotive shops, transmission shops and dealerships. No matter where you look someone is offering some type of transmission fluid change, fluid flush or oil change special. Many non transmission shops offer cheap automatic transmission fluid changes and fluid flushes. Often times much cheaper then most professional transmission repair shops.

Is there really a difference between a lube shop and a transmission repair shop? Yes there several difference such as most lube mechanics are not trained or experienced in transmissions. Most lube mechanics only know how to drain and fill oil. But chances are he won’t be able to identify and take care of any transmission problems. A benefit of having a transmission fluid change or fluid flush is to check the overall operation of the transmission. Having a transmission fluid change or transmission flush is a perfect time to check for transmission oil leaks and adjustments needed. By checking for transmission leaks and adjustments can prevent costly transmission repairs down the road. By taking your car or truck to a professional transmission shop with experienced transmission mechanics is key. An experienced transmission mechanic knows how to identify and fix transmission problems before they get worse. A professional transmission repair shop offering transmission maintenance services often road test the vehicle and perform an under the vehicle inspection.

Beware of cheap transmission fluid services! There a few shops that advertise $8.99 transmission fluid change service. Really $8.99 sounds like a great price, but consideration the fact the new O.E.M. transmission fluid cost are constantly raising. The average cost of a low grade transmission fluid is $2.99 a quart. A basic transmission fluid drain and fill will require at least 5 to 6 quarts of new transmission fluid. So 6 quarts of new transmission fluid x $2.99 a quart = $17.64 cost not to mention labor. The average transmission fluid change service takes between 45 minutes to an hour to properly complete. The transmission industry standard of labor per hour is $75.00. So a basic transmission fluid change cost on average $17.64 in fluid and $75.00 for labor. The total equals $92.64. Yes many repair shops discount the labor involved to attract new customers. But how do you offer a transmission fluid change service for under $20.00. What type of transmission fluid is being used? Who is performing the service? What’s the catch? Why so cheap?

Today’s automatic transmissions require very specific fluid to operate properly and efficiently. Using the wrong transmission fluid could destroy your transmission it in just a few miles. Many drivers believe that a transmission fluid change is a simple and quick service like most oil changes. Often times changing the transmission fluid requires more knowledge and experience than most lube mechanics have. There are thousands cases nationwide where internal transmission damage occurred because of an improper transmission fluid change. Is a cheap transmission fluid change really worth saving a few dollars?

The transmission specialists at Sergeant Clutch offer trained and experienced transmission mechanics. Our transmission mechanics know exactly which transmission fluids to use.

What Can I Do To Keep My Automatic Transmission On The Road Longer?

There are a number of things you can do to keep your automatic transmission working properly for miles and years to come. Most involve maintenance and others involve changing your driving habits.

8 Basic Automatic Transmission Maintenance Tips

1. Check the automatic transmission fluid regularly. Few things will reduce automatic transmission operation and longevity more than low fluid or damaged fluid. If your vehicle has a transmission dipstick, you should check the transmission fluid level and condition at least once a month or every motor oil change.

2. Have the automatic transmission fluid and filter serviced regularly. A regular transmission fluid and filter change can add years and miles o your transmission’s life. In fact, it’s probably the most cost effective maintenance procedure available.

3. Add an external transmission filter in the cooler line. While the filter inside the transmission usually does a good job of removing dirt and particles from the transmission fluid, an extra transmission filter in the cooler line is a great way to make sure of removing all the abrasive particles that can damage your automatic transmission.

4. Check the air pressure in your tires. Low tire pressure can rob your gas tank, wear out your tires, and the rest of your vehicle especially the automatic transmission. The extra load caused by low tire pressure can seriously shorten your transmission’s life. Check the tire pressures at least once a month, and keep them filled to the factory recommendation.

The most common cause of automatic transmission failure is heat. You can get more miles out of your transmission by reducing the heat that builds up during normal operation.

Here are a few things you can do to help reduce heat, and keep your transmission working longer:

1. Avoid Jackrabbit starts. Hard acceleration creates a lot of friction and heat in the automatic transmission. Take it easy on the gas, and your transmission will live longer and perform better.

2. Help the transmission shift. Most of the friction and wear in the transmission takes place during the shifts. Get to know when your automatic transmission shifts normally. Then, just before the shift, back off on the gas just a bit. That’ll reduce the load on the clutches, and eliminate much of the friction during the shift.

3. Keep the cooling system in good shape. Your vehicles radiator also provides cooling for your automatic transmission. And heat damage will take place in the transmission long before the engine appears to overheat. So regular cooling system service can help your transmission run cooler and last longer.

4. Add an external transmission cooler. If you travel a lot in extremely high temperatures or carry a lot of weight in your car or truck, an auxiliary transmission cooler is a great way to reduce heat and add years to your automatic transmission’s life.

Maybe your having transmission problems or just spent money having your transmission repaired. Whatever the reason you’d like to avoid major transmission repairs in the future so take care of your transmission today.

Does Reducing Heat Really Extend The Automatic Transmissions Life?

The most common cause of automatic transmission failure is heat. Reducing the heat that builds up during normal operation of your transmission will prolong the transmissions life.

Here are a few simple things you can do to help reduce transmission heat and keep your transmission working longer.

1. Adding a external transmission cooler has many benefits. If you travel a lot in extremely hot temperatures or carry a lot of weight in your vehicle an auxiliary transmission cooler is a great way to reduce heat and add miles to your transmission’s life. Reducing transmission heat improves overall transmission performance.

2. Keep the vehicles Cooling System in Good operating order increases transmission life. Your vehicles radiator provides cooling for the engine and automatic transmission. Heat damage occurs in the transmission long before the engine appears to overheat. Regular cooling system service can help your vehicles engine and transmission operate cooler and last longer.

3. Avoid Hard accelerations they create a lot of friction and heat in the transmission. Take it easy on the gas and the transmission will last longer.

4. Most of the friction and wear in the automatic transmission takes place during the shifts. Know when the transmission shifts normally. Then just before the transmission shifts back off the gas just a bit. This reduces the load on the transmission clutches and eliminates much of the friction during the shift.

Diagnosing Today's Automatic Transmission Problems

Today's high tech, sophisticated and computer controlled automatic transmissions in many cases could have over a thousand possible problems relating to the transmission. In order to accurately diagnose an automatic transmission problem it requires a series of sophisticated test using high tech state of the art diagnostic equipment. The automatic transmissions from 20 years ago did not require a fraction of the time and skill to diagnose today’s transmission problems.

Many times customers experiencing automatic transmission problems, tend to call around to several auto repair shops or transmission repair shops. One of the first questions asked by the customer is how much is it going to cost? First auto repair shops tend to specialize in other areas of the automobile. So even a qualified automotive mechanic who specialize in other areas of the automobile seldom have the ability to accurately diagnose automatic transmission problems. Most transmission repair shops have the ability to diagnose automatic transmission problems. However no one can accurately diagnose automatic transmission problems over the phone. Auto repair shops and transmission shops that do give prices over the phone without checking the car or truck may be trying their best to do customers a good service. But automotive and transmission repair shops that do quote prices for major automatic transmission repair over the telephone are doing just the opposite. Auto repair shops and transmission repair shops that give prices without performing essential diagnostic test procedures are either guessing or just giving you a meaningless price that will be adjusted later after checking the car or truck.

With virtually thousands of transmission variables no one can accurately diagnose automatic transmissions over the phone. The same is true in automatic transmission diagnosis. Any meaningful transmission diagnosis can only be rendered after a complete inspection of the car or truck is performed.

What are some signs of automatic transmission problems?

Are you experiencing loss of power upon acceleration?

Is your automatic transmission unable to go into gear?

Is your automatic transmission not shifting?

Is your automatic transmission shifting hard or sifting late?

Is your automatic transmission slipping?

Is you automatic transmission making a chatter or grinding noise?

Is your automatic transmission leaking fluid?

Is your car or truck not drivable?

What’s Wrong With My Automatic Transmission?

To find out what‘s wrong with today‘s automatic transmission, a certified transmission mechanic will to have to perform a series of comprehensive diagnostic tests to determine if the automatic transmission problem is inside the transmission or outside. If the transmission problem is inside the transmission it could be caused be normal wear and tear or part failure. If the automatic transmission problem is outside the transmission it could be one of the many high tech computerized control systems that operates the transmission? The transmission of today has a lot more to the transmission operation and performance than the transmission itself.

Fact today’s automatic transmissions are controlled by high tech electronic computer systems integrated with the rest of the automobile that many automotive mechanics have a difficult time determining whether a transmission problem is inside the transmission or not. So a problem with the engine or brakes could have a huge effect on automatic transmissions operation and performance. Many times the first sign of a problem is when the “Check Engine Light”, “Service Engine Soon” or “Transmission OD Light” comes on.

Only a well trained, experienced automatic transmission mechanic can be sure you actually have a transmission problem. A properly trained, experienced and certified transmission mechanic examines the automobile and performs the necessary diagnostic test, there’s no way anyone can tell you for sure what’s wrong with your transmission.

What Is A Sergeant Clutch Free Transmission Performance Check?

Fact today's automobiles and automatic transmissions are primarily all computer controlled sophisticated pieces of high tech technology on wheels. The automobiles and automatic transmissions of today require high tech onboard computers to operate properly. This high tech computer technology plays a significant part in the proper diagnosis of today’s automobiles and automatic transmissions. The automobiles general performance and automatic transmission performance is computer controlled.

When your automobiles onboard computer system recognizes a problem in one or more of the many different systems it monitors and controls, such as the engine or transmission it will illuminate the "Check Engine Light" / “Service Engine Soon Light” / “Transmission Light“. This “Check Engine Light” / “Service Engine Soon Light” / “Transmission Light” indicates something is not right with the automobile. Many times the problem is noticed by the driver and some problems are not made obvious. In order to understand what the automobiles computer is trying to communicate a professional computer diagnostic test is needed to determine what part or parts are malfunctioning. If your “Check Engine Light”, “Service Engine Soon” .“Transmission Light” are on or you think your having transmission problems, bring your automobile to Sergeant Clutch Discount Transmission & Automotive in San Antonio, Texas for a comprehensive FREE Transmission Performance Check.

Sergeant Clutch Discount Transmission & Automotive offers a comprehensive FREE Transmission Performance Check which is a series of test. This Computer Diagnostic Service utilizes state-of-the art diagnostic equipment, which is connected to your automobile to view computer trouble codes. Sergeant Clutch trained transmission mechanic utilizes the same procedures the dealerships perform by retrieving information directly from the automobile's data stream to accurately pinpoint automobile system failure(s) or service(s) needed. The Computer Diagnostic Service provides you with an accurate assessment of your automobile's condition including the transmission. After the automobile computer data is retrieved our mechanic can provide an accurate recommendation to get you back on the road quickly and efficiently. This comprehensive transmission performance check provides a complete diagnosis of your automobile’s transmission performance and general operation.

With our step by step transmission diagnostic service, our transmission mechanic will find what transmission problem(s) you have. The Transmission Performance Check consists of a compressive transmission fluid check, road test, transmission pan examination, under car inspection and computer diagnostic scan. The automatic transmission fluid check is generally the first indicator of possible transmission problems. Under close observation the transmission fluid and smell can indicate transmission wear and damage. If there is an unpleasant odor or discoloration in combination with other symptoms the transmission may require further diagnostics and a possible internal transmission inspection. An automatic transmission in good operating condition will have a red fluid color, no contaminates and no burnt smell.

The road test is made up of a stationary test and a driving test. During these two tests, the automatic transmission is checked for initial engagements, slipping, vibrations, noises, harsh shifting, soft shifting, erratic shifting, late shifting, early shift patterns, passing gear, torque converter clutch engagement. Our transmission mechanic will perform an under the automobile inspection to help determine what type of adjustment(s), repair(s) or replacement(s) may be needed. During the under the automobile inspection our mechanic will check the following: Neutral Switch, Throttle Linkage, Manual Linkage, Cooler Lines, Modulator, Modulator Vacuum, Electronic Components, Harness connections, Wire condition, Transmission pan gasket, front seal, rear seal, axle seals, rear main seal, Transmission Mounts, U-Joints and Cv Axles.

The automatic transmission oil pan examination can be a great indicator of potential transmission problems. By removing the transmission oil pan it allows our mechanic to take a partial look inside the transmission. All automatic transmission oil pans will have some metal particles in the transmission fluid or on the oil pan magnet. However, an excessive amount of metal indicates internal transmission wear and damage.

When the results of your transmission performance check show that there is an internal problem with your automatic transmission, we recommend further investigation with an internal inspection of your transmission. This internal transmission inspection consists of the removal of your automatic transmission and disassembly of the unit in order to view all internal transmission parts. During this transmission inspection, all parts will be examined for wear and damage. When the internal transmission inspection is completed, our Service Manager will provide you with a full report of those transmission items that are in need of either repair, replacement, or upgrade along with an estimate for those transmission repair services.

Top 6 Tips How To Avoid Transmission Scams and Transmission Rip-Offs

Having a transmission problem can be very timely and expensive auto repair. The automatic transmission and torque converter have become much more complex, computerized and expensive. These new designs have made the automatic transmission and torque converter more reliable these days, but still automatic transmissions do tend to wear out and break down. Some automatic transmission rebuilds can easily cost $2,000.00 or more.

1. The most important information you need to know is the year, make, model, engine size, and in some cases the VIN# of the automobile with problems. In order to get accurate information and estimates you got to have this information

2. When describing the transmission problems you are experiencing be as descriptive as possible. When does the problem happen and how often. When was the first time you noticed the problem(s).Mention if any indicator lights are on such as Check Engine Light, Service Engine Light Soon Light, Transmission Light, OD Light, etc.

3. Always get recommendations of friends, family and co-workers to recommend a local transmission repair shop where they were treated fair and were happy with the transmission repairs and services.

4. Always look for a professional auto repair shop appearance. A transmission repair shop that is clean, organized and busy indicates a professional business attitude and work environment.

5. Always avoid telephone cost estimates for transmission repairs. Today’s automobiles make it virtually impossible for anyone to give an accurate transmission repair cost estimate over the telephone. Any transmission repair shop / auto repair shop that gives you an exact cost estimate for major transmission repairs before they physically check the car / truck are probably giving you a “low ball” transmission cost repair estimate. To get an accurate cost estimate for transmission repairs requires a series of trans-check procedures.

6. Always ask for a detailed written cost estimate for any transmission repairs, service or recommendations. After a complete transmission performance check of your car / truck the transmission repair shop should have a fairly good idea of what’s wrong with your car / truck transmission. The transmission repair shop or auto repair shop should be able to provide you a written cost repair estimate of any needed or recommended transmission repairs or service(s). The written cost repair estimate should have a detailed deception of what’s wrong with the transmission. The written cost repair estimate should also include the warranty and complete cost of all repairs and services.

How To Test Drive An Automatic Transmission Before Buying Automobile

Use more caution when test-driving someone else's vehicle. Always check the mirrors, the driver's seat, etc. may not be adjusted properly for you. First, get use to the brake pedal feeling, adjust the mirrors, driver's seat, and learn all the controls of the vehicle. Then proceed to drive when you are sure it's safe.

One of the indications of a automatic transmission problem is delayed engagement, when there is a long delay between the moment you shift the shifter into "D" (Drive) or "R" (Reverse) and the moment the transmission kicks in. It's easier to note delayed automatic transmission engagement after a car / truck has been sitting for a while: With the automatic transmission in "P" (Park) start the engine, and wait until the engine rpm has reduced to normal level (650 - 850 rpm). With your foot holding down the brake pedal, shift to the "D" (Drive) position. Almost immediately the automatic transmission should engage. It feels like the car wants to creep forward. This should happen very smoothly, without a strong jerk or clunk. Shift to "N" (Neutral), and the transmission should disengage. Now, still holding the brakes, shift to the "R" (Reverse) position. Again, the transmission kicks in almost immediately. You will feel the car wants to creep backward. This also should be very smooth, without a jerk or clunk.

Now, still holding the brake pedal down, try to shift from D to R and back to D. There should be no strong jerk or clunk. (clunk sound could be a transmission mount). If there is a notable long delay (more than 1 seconds) between the moment you shift and the moment the transmission kicks in, such a transmission might be either too worn or has some problem, avoid this car / truck. If you feel a strong jerk or clunk while shifting, the car / truck may have a transmission problem.

Now it's time to test drive the automobile. With the shifter in "D" (Drive) position drive gently, with smooth and gradual acceleration. Until the automobile reaches a speed of 30-37 mph (50-60 km/h) or you should feel the gears shifting at least twice (from first to second, and from second to third gear). All shifts should be done very smoothly, without jerks or slipping. You should be able to feel when the transmission shifts by the slight change in the engine tone or change in engine rpm. If the transmission is extremely worn it may shift with quite a strong jerk, shudder or a delay (especially from first to second gear). Driving at a speed of 25-30 mph (40-50 km/h) if you press down the accelerator pedal for a few seconds, you should feel downshifting to the lower gear, if the automatic transmission works properly. The next step is to check the automatic transmission overdrive. While driving at 60-70 km/h or 35-45 mph on a level road, without using the accelerator, switch overdrive ON. You should feel an upshifting to the next speed. Switch it to "OFF," and you should feel a downshifting. Another sign that may indicate the transmission problem is the slipping. When the transmission is excessively worn it may slip which means when you press the accelerator, the engine rpm increases but the speed remains the same. If during the drive test you feel any problem such as the transmission seems to slip or shifts with a jerk or shudder or if the transmission got stuck in some gear, or has trouble shifting into a particular gear (for ex. from second to third), avoid buying such a automobile.

Test-drive the car as long as possible. Often the automatic transmission may work well when it's cold but when it's warmed up the transmission starts having problems. It's best to spend more time checking the transmission than later fixing it endlessly. Normally there should be no transmission shudder, no transmission noises or any kind of transmission jerks at any speed and at any engine temperatures. If the salesperson tells you that the jerks or shudder or any other abnormal transmission behavior is "normal" for this automobile or it's just because the automobile is cold or anything like that don't trust them. If the "check engine light" is on and/or a flashing overdrive light comes on while driving, this is a sign of a potential transmission problem. Have the transmission problem checked by your transmission mechanic before buying automobile.

How To Check An Automatic Transmission Before Buying Automobile

First, check the transmission fluid level and condition. If you can’t find the transmission dipstick check the vehicles owner manual.

Keep in mind, however, that some modern cars simply don't have the transmission dipstick and require special procedure performed in a transmission repair shop to check the transmission fluid level.

The automatic transmission and torque converter have become much more complex and computerized. These designs have made the automatic transmission and torque converter more reliable these days, but still automatic transmissions do tend to wear out and break. Its very important to always change transmission fluid. Many car owners tend to perform regular car maintenance such as oil change, check tire air pressure and air filter. Many car owners overlook checking the automatic transmission fluid. The automatic transmission fluid doesn’t need to be changed as often as changing the motor oil but the transmission fluid should be checked every time you change motor oil. The automatic transmission fluid level should be checked by pulling the transmission / transaxle dipstick. The transmission fluid level should mark at least to the full mark on the transmission dipstick. The transmission fluid should have a reddish color. The automatic transmission fluid should not be brownish or black like motor oil. The automatic transmission fluid should not smell burnt. A burnt smell is a sign of transmission problems. The transmission should not have bubbles on the dipstick. Bubbles on the transmission dipstick is a sign of excessive heat and that means the transmission is getting too hot. Heat is the key factor in automatic transmission problems. Also check the transmission fluid for any signs of metal shavings mixed with the transmission fluid. Metal in the transmission fluid is a sign of transmission problems.

Having a transmission problem can be very timely and expensive, The automatic transmission is a complex and expensive part of the vehicle. If the automatic transmission is heavily abused, the transmission can be easily destroyed within just half an hour of driving with a transmission problem. An automatic transmission and torque converter are very sensitive to the transmission fluid quality and condition. Improper transmission fluid such type of fluid) can damage the automatic transmission.

Obviously, when buying a used car, the automatic transmission is one of the most important parts to check. A potential transmission problem in a used car. Can ending up cost you a lot more then you bargained for. You should always have any vehicle you are considering buying checked by a professional mechanic before purchasing.

How to check the automatic fluid turn on the automobile and let the engine idling, transmission in "Park" (some car may have different procedure, refer to owner's manual) remove the automatic transmission dipstick and wipe it out with the clean cloth. Then insert it back and pull out again. Check the fluid level, low level may indicate a transmission leak. Look at the transmission fluid very closely. It helps to drip the transmission fluid on a white paper to be able to see fluid condition. The transmission fluid on the paper should be clean and transparent, without any metal filings or black flakes. New transmission fluid usually comes red. Over the time and use it become more brownish, but it shouldn't be black. Try to smell the transmission fluid. It should not have a burnt smell. If you discover that transmission fluid is too dirty or black, or smells burnt, avoid buying such a car

If the transmission problem is in the vehicles computer system, the mechanic will probably have to perform additional diagnosis test to further identify the specific cause of the problem. These test may take a half hour, or may take two hours depending on severity of the problem. Once the transmission mechanic has identified the specific problem, the repair shop may be able to give you a relatively accurate repair cost estimate to fix your car or truck. If the problem is inside the transmission, the transmission repair shop may be able to give you a transmission rebuild price cost based on the type of transmission. In most cases that price cost estimate will be accurate within about 15% to 20%. No transmission repair shop can give you a firm cost to repair your transmission until they have the transmission apart, and have examined it for any damage that wasn’t visible while the transmission was still in the vehicle.

The good news is that the vast majority of transmission problems that come into Sergeant Clutch Discount Transmission & Automotive shop these days don’t actually end up needing a new transmission.

How Much Will An Automatic Transmission Rebuild Cost?

Transmission repair costs depend on first what is wrong with the transmission and second what parts may be required to correct the problem. Overall 60% of all transmission repairs are minor ones that do not require a complete overhaul of the transmission. Minor transmission repairs include transmission fluid change or fluid flush, transmission reseal or replacement of electrical transmission solenoid or sensor. Minor transmission repairs usually start at $49.95 and can range up to a few hundred dollars depending on parts and labor needed to fix the problem(s). Major transmission repairs usually start at $695.00 for a basic transmission overhaul and over $2,000.00 for extensive transmission hard part damage and or electrical sensors and solenoids. A reman transmission or new transmission can have a price tag of $1,800.00 to over $3,500.00 depending on year, make and model.

Today's transmissions are high tech, computerized and sophisticated. In order to determine what the transmission problem is and how much will it cost, requires extensive testing to determine the reason for failure.

Why Can't You Tell Me Exactly The Cost To Fix My Transmission Without Dismantling It?

You’d be amazed at how many customers want us to diagnose their transmission problems over the phone. Aside from the fact that a customer might easily miss a symptom a trained mechanic would see or hear when the vehicle is brought in, can you tell the difference between a rattle, buzz, grind, whine and a slip? And do you mean the same thing by those words as we do?

Twenty plus years ago the transmission industry was very basic. Back then there were only a dozen different transmissions on the road. Most every transmission repair shop had a good stock of rebuilt transmission units on hand. There were almost no transmission updates necessary and even if some usual part failed most transmission shops had a good supply of used and new transmission parts on hand to replace it. In today’s transmission market there are more than a hundred transmissions in use and new transmissions showing up all the time. Many of those transmissions have several different gear variations or calibrations, with as many as a dozen modifications necessary. To provide you with an accurate cost estimate of your transmission’s condition. Our transmission mechanic must perform a series of rigorous tests. The mechanic must identify which transmission is in your automobile and which version of that transmission it is. Then they have to identify the specific transmission problem and isolate whether it’s in the transmission or the computer system. Finally, they have to determine the likely causes for the problem, based on a logical diagnostic process. Once the mechanic has that information, our Service Manager is able to give you an accurate explanation of your automobile’s condition.

The plain truth is we simply can’t be sure of what’s wrong with your transmission until we take a look inside. Nobody can. Transmission problems and symptoms can be observed externally like noises, leaks or vibrations. These symptoms can signal a wide range of possible problems, not necessarily a single problem or malfunction. Also, many problems that can occur with today’s transmissions maybe caused by a component outside the transmission like a Throttle Position Sensor, a MAP sensor, or even a simple fuse. We’ve got to give your transmission a thorough checkup to really now what’s causing the transmission problem. If anyone ever tells you they can accurately diagnose what’s wrong with your transmission without a thorough diagnosis (which may include looking inside), you’d better get a second opinion.

Sergeant Clutch will be able to let you know what it’ll take to fix your car or truck. Fact the vast majority of customers who bring their automobile in with transmission problems don’t actually need their transmissions rebuilt. In most cases the transmission problem turns out to be an external problem, which usually costs far less than a transmission rebuild or new transmission.

Why Does It Cost So Much To Have A Transmission Repaired or Rebuilt?

It really doesn’t. At least, it doesn’t when you understand what is required to repair, overhaul, or rebuild your transmission. Repairing or rebuilding a transmission is not as simple as changing spark plugs or adjusting the carburetor. Today’s transmission particularly those with front wheel drive or all wheel drive systems are extremely complicated transmissions. There are over three thousand parts in today’s average automatic transmission. And the transmission parts for some late model imports can cost ten times as much as parts for older, larger domestic automobiles. Just getting to the transmission parts you need to inspect in order to find out what’s wrong with the transmission often requires major surgery especially on smaller cars where the manufacturer has tightly packed different parts and mechanical systems on top of and around each other.

During a major transmission repair or rebuild, the entire transmission assembly is removed for the automobile. Then the transmission is dismantled and the internal transmission parts are cleaned off. Next the transmission parts are carefully inspected for parts tolerance, worn parts or damaged parts. A transmission parts list is then created from the parts required to correctly repair, overhaul or rebuild transmission. Upon customer approval the transmission is then deep cleaned and prepared to reinstallation of transmission parts. Each transmission part is assembled together into one of many subassemblies in the transmission. Each subassembly must be properly adjusted and tested for proper operation. Then the subassemblies must be assembled into the transmission case. Once in the case the adjustment and testing procedure begins all over again. Once the transmission is completely assembled, its ready to be reinstalled in the automobile. Before the new repaired or rebuilt transmission is reinstalled in the car or truck the transmission cooler lines are flushed. This cooler line flush procedure removes old transmission and containments stuck in the transmission cooler lines going to the radiator. After the mechanic installs the transmission its time for computer reprogramming and test drives. As you can see there is huge amount of time, skill and labor involved with a transmission repair or transmission rebuild. With such complex transmissions, preventive maintenance such as transmission fluid change and fluid flush are the key to keeping transmission repair costs down. To help head off major transmission problems, Sergeant Clutch recommends having your transmission serviced at least every 12,000 miles or once a year.

What Is A Reman / Remanufactured Transmission?

A reman / remanufactured transmission is generally a transmission that has been completely reconditioned on a mass assembly line process as opposed to a custom rebuild process. The quality of remanufactured transmissions vary greatly depending on which company remanufactured the transmission and the remanufactures set of rebuild standards.

The big decision of whether or not to use a remanufactured transmission or a custom rebuilt transmission has many variables. How do you use your vehicle? Is the transmission in your vehicle a problematic transmission or a more simple type transmission? How long do you plan to keep the vehicle? Is your vehicle subjected to any special driving conditions such as extreme hot or cold weather, unusual mountainous terrain, city use or towing?

The automatic transmission is a high tech mechanical and computerized assembly that transmits power from the automobile engine to the drive train which makes the wheels move and drive the automobile.

Sergeant Clutch currently offers several Transmission Warranty options. We provide transmission repair customers Sergeant Clutch's Standard 12 month / 12,000 mile worry free warranty protection on all qualifying transmission parts and labor. We also offer a 90 day / 4,000 mile parts and labor warranty, 24 month / 24,000 mile parts and labor warranty, 36 month / 36,000 mile parts and labor warranty and a 36 month / 50,000 mile parts & labor warranty ask for more details.

Used Junkyard Transmission Replacement Versus Rebuilt Transmission Replacement

Now the real truth about transmissions Used Junkyard Transmission Replacement Versus Rebuilt Transmission Replacement

QUESTION: Why pay $ 400.00 to over $1,000.00 for a cheap used junkyard transmission and torque converter replacement? When in most cases for a few hundred dollars more, you could repair transmission, rebuild transmission, remanufactured transmission or even buy a new transmission.

Many times drivers overlook the fine print details involved with buying a used transmission and torque converter from a junkyard / salvage yard. Many times the junkyard / salvage yard has no clue as to the history of the automobile they part out. They may know the mileage but they do not know if the transmission and torque converter are all original or has the transmission fluid been changed or flushed. Many times transmissions and torque converters found at junkyards / salvage yards have been involved in an accident or fire. Most junkyards / salvage yards store used transmissions and torque converters outside and are exposed to water and the elements. Once water contaminates an automatic transmission, manual transmission or torque converter it is damaged and will not operate properly. Water damages the transmission solenoids, transmission electrical parts, the clutch lining material on the clutches inside the transmission and torque converter are contaminated; many junkyards / salvage yards rate a transmission by the condition of the transmission fluid. By just checking, the transmission fluid does not properly evaluate the internal transmission parts. Water also rust forms on the internal transmission metal parts and bearings. Heat damages the transmission seals both external and internal. Most junkyards / salvage yards sale transmissions with no warranty, as is, some offer 30 day guarantee on parts only no labor. Some high tech junkyards / salvage yards sale transmissions with extended warranty for a premium up charge. Remember just because the junkyard / salvage sales you better guarantee on the transmission it does not mean the transmission is any better. I just means if the first transmission they sale you does not work they will simply give you another junkyard transmission and hope this transmission out last the extended the warranty they sold you. What happens if the used transmission from the junkyard goes bad under the warranty? You will have to remove the transmission from the automobile and return it to the junkyard / salvage yard. What happens if the junkyard does not have another transmission like the one you need in stock? You wait for them to get another transmission. Most junkyards / salvage yards will not refund any money. There many complications in dealing with used transmissions such as correct type but wrong model. Many times transmissions have one or two things different from bolt hole in the wrong spot to electrical connector in the wrong place. Many customers that compare rebuilt transmission prices vs. used transmission prices lose sight of a few things. At first, the used transmission price may seem cost efficient verses rebuilt transmission price. Here is an example of the correct way to calculate the cost of a used junkyard transmission replacement.

Cost of used transmission(just for example purpose only) $800.00

Cost of extended warranty coverage for used transmission and torque converter. That is if the junkyard / salvage yard offers a warranty. (Average) $50.00

Cost of labor to remove and replace transmission. (Average) $600.00

Cost of new transmission fluid. (Average 10 qts) $35.00

Cost of transmission flush additive. The transmission lines must be flushed before installing transmission replacement. (Average) $15.00

Cost of recommended transmission parts to ensure warranty if warranty applies. A used transmission should have at least the front transmission seal replaced, rear transmission seal, transmission axle seals, transmission pan gasket and transmission filter. (Average cost with labor) $80.00

Cost of transmission diagnostic test and relearn process. Most transmission have sensors, solenoids and computers that must be reset and reprogrammed after a transmission replacement or transmission repair. (Average Cost) $75.00

Cost of tow truck service to auto repair shop or mechanics house. (Average Cost) $75.00

Now let us add up the average total for a used junkyard / salvage yard transmission.

$800.00

$50.00

$600.00

$35.00

$15.00

$80.00

$75.00

TOTAL = $1,730.00

This average cost of a used transmission replacement still has many other possible hidden costs involved. If the used transmission does not work properly the first time or anytime after you will have to pay for the labor again to remove and replace the transmission. You will have to pay for labor again to remove the transmission since the mechanic or auto repair shop will not give you a warranty for labor on a used transmission. Therefore, the labor would be an additional $600.00 on average. In addition, new transmission fluid as the transmission fluid first used may be contaminated now. In addition, another transmission line flush average cost $15.00. In addition, the cost of new front transmission seal replaced, rear transmission seal, transmission axle seals, transmission pan gasket and transmission filter. (Average cost with labor) $80.00. Plus transmission computer diagnostic testing and relearn process average cost $75.00. In addition, towing service if your transmission goes out on you and leaves you stranded average cost $75.00. Not to mention all the time involved in this process. All the missed appointments and inconveniences. In addition, you do not really know when or where that used transmission may go out. So lets add up the original average cost of a used transmission replacement $1,730.00 plus the cost of a possible transmission problem occurring with the used transmission replacement.

$1,730.00 Average cost of used junkyard / salvage yard transmission replacement

$845.00 Average cost of replacing used transmission after first installation.

Total $2,575.00 not to mention the cost of another used junkyard transmission if the original used transmission you purchased has No Warranty. Then you have to buy another transmission. Let us just say worst-case scenario it happens. You buy another used transmission for $800.00 average. Now add the second transmission replacement to the $2,575.00 now the total of the used junkyard / salvage transmission replacement cost you $3,375.00. I know it sounds extreme and a little crazy how a used transmission replacement ended up costing over $3,000.00 still with no really assurance that the transmission will not break down again.

Some customers get sticker shock when first hearing the cost of repair transmission or rebuilt transmission. However, the cost of rebuilt automatic transmission includes many benefits over the used junkyard transmission replacement. Such as free towing to the auto shop, complete computer diagnostics, complete transmission overhaul including all new transmission parts such as new transmission seals, new transmission gaskets, new transmission o’ rings, new transmission clutches, new transmission filter, new or rebuilt torque converter, new transmission solenoids, new transmission sensors, etc. In addition, a rebuilt transmission repair service includes a transmission warranty for parts and labor for 1 year / 12,000 miles up to 3 year / 50,000 miles. Now that’s piece of mind knowing your transmission that belongs in your car or truck has been completely dismantled , inspected , cleaned, all worn and damaged transmission parts have been replaced and backed by a transmission parts and labor warranty. The average cost of a basic automatic transmission overhaul is $885.00 parts and labor. The cost of a major transmission rebuild is $1,500.00 to $2,200.00 parts and labor. The cost of a transmission repair service always depends on what transmission parts are bad, broken, worn or recommended. Isn’t it better to spend a little more the first time a get the repair job done right, instead of a lot more later?

What Is The Purpose Of An Automatic Transmission?

The automatic transmission is part between the engine and differential. The automatic transmissions purpose is to transmit engine torque to the driving wheels. This is done through a number of reduction gears and the use of a torque converter. An automatic transmission performance can only be as good as the power supplied to it by the engine and the driving members to which this power is transmitted through the drive shaft and differential. A rough running engine can only result in a rough shifting automatic transmission.

What Is An Automatic Transmission?

An automatic gearbox is one type of motor vehicle transmission that can automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually. Most automatic transmissions have a defined set of gear ranges, often with a parking pawl feature that locks the output shaft of the automatic transmission. Besides automatic transmissions, there are also other types of automated transmissions such as continuous variable transmission (CVTs) and semi-automatic transmissions, that free up the driver from having to shift gears manually by using the transmission's computer to change gear, if for example the driver were redlining the engine. Despite superficial similarity to other automated transmissions, automatic transmissions differ significantly in internal operation and driver's "feel" from semi-automatics and CVTs. An automatic uses a torque converter instead of a clutch to manage the link between the transmission and the engine, while a CVT uses a belt instead of a fixed number of gears, and a semi-automatic transmission retains the clutch like a manual but activates the clutch through electrohydraulic means.

A conventional manual transmission is frequently the base equipment in a car or truck, with the option being an automated transmission such as a conventional automatic transmission, manumatic transmission, semi-automatic transmission , or CVT transmission. The ability to shift gears manually, often via paddle shifters, can also be found on certain automated transmissions (manumatic such as Tipronic), semi-automatics (BMW SMG), and continuous variable transmissions (CVTs) (such as Lineartronic).

What Is A Manually Controlled Automatic Transmission?

Most automatic transmissions offer the driver a certain amount of manual control over the transmission's shifts beyond the obvious selection of forward, reverse, or neutral. Those controls take several forms:

Throttle Kickdown: Most automatic transmissions include some means of forcing a downshift into the lowest possible gear ratio if the throttle pedal is fully depressed. In many older designs, kickdown is accomplished by mechanically actuating a valve inside the transmission. Most modern designs use a solenoid operated valve that is triggered by a switch on the throttle linkage or by the engine control unit (ECM) in response to an abrupt increase in engine power.

Mode Selection: Allows the driver to choose between preset shifting programs. For example, 'Economy Mode' saves fuel by upshifting at lower engine speeds, while 'Sport Mode' delays shifting for maximum acceleration. The modes also change how the computer responds to throttle input.

Low Gear Ranges: Conventionally, automatic transmissions have selector positions that allow the driver to limit the maximum ratio that the transmission may engage. On older transmissions, this was accomplished by a mechanical lockout in the transmission valve body preventing an upshift until the lockout was disengaged; on computer-controlled transmissions, the same effect is accomplished by firmware. The transmission can still upshift and downshift automatically between the remaining ratios: for example, in the 3 range, a transmission could shift from first to second to third, but not into fourth or higher ratios. Some transmissions will still upshift automatically into the higher ratio if the engine reaches its maximum permissible speed in the selected range.

Manual Controls: Some transmissions have a mode in which the driver has full control of ratio changes (either by moving the selector, or through the use of buttons or paddles), completely overriding the automated function of the hydraulic controller. Such control is particularly useful in cornering, to avoid unwanted upshifts or downshifts that could compromise the vehicle's balance or traction. "Manumatic" shifters, first popularized by Porsche in the 1990s under the trade name Tiptronic, have become a popular option on sports cars and other performance vehicles. With the near-universal prevalence of electronically controlled transmissions, they are comparatively simple and inexpensive, requiring only software changes, and the provision of the actual manual controls for the driver. The amount of true manual control provided is highly variable: some systems will override the driver's selections under certain conditions, generally in the interest of preventing engine damage. Since these gearboxes also have a throttle kickdown switch, it is impossible to fully exploit the engine power at low to medium engine speeds.

Second Gear Takeoff: Some automatics, particularly those fitted to larger capacity or high torque engines, either when '2' is manually selected, or by engaging a "winter mode", will start off in second gear instead of first, and then not shift into a higher gear until returned to D. Also note that as with most American automatic transmissions, selecting "2" using the selection lever will not tell the transmission to be in only 2nd gear, rather, it will simply limit the transmission to 2nd gear after prolonging the duration of 1st gear through higher speeds than normal operation. The 2000-2002 Lincoln LS V8 (the five-speed automatic without manumatic capabilities (as opposed to the optional sport package w/ manu-matic 5sp) started in 2nd gear during most starts both in winter and summer by selecting the "D5" transmission selection notch in the shiftgate for fuel savings, whereas "D4" would always start in 1st gear. This is done to reduce torque multiplication when proceeding forward from a standstill in conditions where traction was limited on snow, or ice covered roads, for example. Some automatic transmissions modified or designed specifically for high performance drag racing may also incorporate a transmission brake, or "trans-brake," as part of a manual valve body. Activated by electrical solenoid control, a trans-brake simultaneously engages the first and reverse gears, locking the transmission and preventing the input shaft from turning. This allows the driver of the car to raise the engine RPM against the resistance of the torque converter, then launch the car by simply releasing the trans-brake switch.

What Parts Are Inside An Automatic Transmission?

The predominant form of an automatic transmission is hydraulically operated using a fluid coupling or torque converter, and a set of planetary gear sets to provide a range of gear ratios.

A hydraulic automatic transmission consists of the following parts:

The torque converter: A type of fluid coupling, hydraulically connecting the engine to the automatic transmission. It takes the place of a mechanical clutch, allowing the automatic transmission to stay 'in gear' and the engine to remain running while the vehicle is stationary, without stalling. A torque converter differs from a fluid coupling, in that it provides a variable amount of torque multiplication at low engine speeds, increasing "breakaway" acceleration. This is accomplished with a third member in the "coupling assembly" known as the stator, and by altering the shapes of the vanes inside the coupling in such a way as to curve the fluid's path into the stator. The stator captures the kinetic energy of the transmission fluid, in effect using the leftover force of it to enhance torque multiplication.

The Pump: Not to be confused with the impeller inside the torque converter, is typically a gear pump mounted between the torque converter and the planetary gear set. It draws transmission fluid from a sump and pressurizes it, which is needed for automatic transmission components to operate. The input for the pump is connected to the torque converter housing, which in turn is bolted to the engine's flywheel, so the transmission pump provides pressure whenever the engine is running and there is enough transmission fluid.

The Planetary Gear Set: A compound epicyclic planetary gear set, whose bands and clutches are actuated by hydraulic servos controlled by the valve body, providing two or more gear ratios.

The Clutches and Bands: To effect gear changes, one of two types of clutches or bands are used to hold a particular member of the planetary gear set motionless, while allowing another member to rotate, thereby transmitting torque and producing gear reductions or overdrive ratios. These clutches are actuated by the valve body, their sequence controlled by the automatic transmission's internal programming. Principally, a type of device known as a sprag or roller clutch is used for routine upshifts / downshifts. Operating much as a ratchet, it transmits torque only in one direction, free-wheeling or "overrunning" in the other. The advantage of this type of clutch is that it eliminates the sensitivity of timing a simultaneous clutch release/apply on two planetaries, simply "taking up" the drivetrain load when actuated, and releasing automatically when the next gear's sprag clutch assumes the torque transfer. The bands come into play for manually selected gears, such as low range or reverse, and operate on the planetary drum's circumference. Bands are not applied when drive/overdrive range is selected, the torque being transmitted by the sprag clutches instead. Bands are used for braking; the GM Turbo-Hydramatics incorporated this.

The Valve Body: A hydraulic control center that receives pressurized fluid from the main pump operated by the fluid coupling/torque converter. The pressure coming from this pump is regulated and used to run a network of spring-loaded valves, check balls and servo pistons. The valves use the pump pressure and the pressure from a centrifugal governor on the output side as well as hydraulic signals from the range selector valves and the throttle valve or modulator to control which ratio is selected on the gear set as the vehicle and engine change speed, the difference between the pressures changes, causing different sets of valves to open and close. The hydraulic pressure controlled by these valves drives the various clutch and brake band actuators, thereby controlling the operation of the planetary gear set to select the optimum gear ratio for the current operating conditions. However, in many modern automatic transmissions, the valves are controlled by electro-mechanical servos which are controlled by the electronic engine control unit (ECU) or a separate transmission control unit (TCU).

The Hydraulic & Lubricating Oil: Automatic transmission fluid (ATF), this component of the automatic transmission provides lubrication, corrosion prevention, and a hydraulic medium to convey mechanical power for the operation of the transmission. Primarily made from refined petroleum, and processed to provide properties that promote smooth power transmission and increase service life, the ATF is one of the few parts of the automatic transmission that needs routine service as the vehicle ages.

The multitude of parts, along with the complex design of the valve body, originally made hydraulic automatic transmissions much more complicated and expensive to build and repair than manual transmissions. In most cars except US family, luxury, sport-utility vehicle, and minivan models they have usually been extra-cost options for this reason. Mass manufacturing and decades of improvement have reduced this cost gap.

What Is The Torque Converter?

The torque converter is a type of fluid coupling, hydraulically connecting the engine to the automatic transmission. It takes the place of a mechanical clutch, allowing the automatic transmission to stay 'in gear' and the engine to remain running while the vehicle is stationary, without stalling. A torque converter differs from a fluid coupling, in that it provides a variable amount of torque multiplication at low engine speeds, increasing "breakaway" acceleration. This is accomplished with a third member in the "coupling assembly" known as the stator, and by altering the shapes of the vanes inside the coupling in such a way as to curve the fluid's path into the stator. The stator captures the kinetic energy of the transmission fluid, in effect using the leftover force of it to enhance torque multiplication.

What Is Torque Converter Overloading?

Overloading a converter can result in several failure modes, some of them potentially dangerous in nature:

Torque Converter Overheating: Continuous high levels of slippage may overwhelm the torque converter's ability to dissipate heat, resulting in damage to the elastomer seals that retain fluid inside the torque converter. This will cause the torque converter to leak and eventually stop functioning due to lack of transmission fluid.

Torque Converter Stator Clutch Seizure: The inner and outer elements of the one way stator clutch become permanently locked together, thus preventing the stator from rotating during the coupling phase. Most often, seizure is precipitated by severe loading and subsequent distortion of the clutch components. Eventually, galling of the mating parts occurs, which triggers seizure. A torque converter with a seized stator clutch will exhibit very poor efficiency during the coupling phase, and in a motor vehicle, fuel consumption will drastically increase. Torque converter overheating under such conditions will usually occur if continued operation is attempted.

Toque Converter Stator Clutch Breakage: A very abrupt application of power can cause shock loading to the stator clutch, resulting in breakage. When this occurs, the stator will freely counter-rotate the pump and almost no power transmission will take place. In an automobile, the effect is similar to a severe case of transmission slippage and the vehicle is all but incapable of moving under its own power.

Torque Converter Blade Deformation and Fragmentation: Due to abrupt loading or excessive heating of the converter, the pump and/or turbine blades may be deformed, separated from their hubs and/or annular rings, or may break up into fragments. At the least, such a failure will result in a significant loss of efficiency, producing symptoms similar (although less pronounced) to those accompanying stator clutch failure. In extreme cases, catastrophic destruction of the torque converter will occur.

Torque Converter Ballooning: Prolonged operation under excessive loading, very abrupt application of load, or operating a torque converter at very high RPM may cause the shape of the converter's housing to be physically distorted due to internal pressure and/or the stress imposed by centrifugal force. Under extreme conditions, ballooning will cause the converter housing to rupture, resulting in the violent dispersal of hot oil and metal fragments over a wide area.

What Are Automatic Transmission Modes & Gears?

Conventionally, in order to select the automatic transmission operating 'mode', the driver moves a selection lever (gear shifter) located either on the steering column or on the floor. In order to select transmission modes, or to manually select specific transmission gear ratios, the driver must push a button in called the shift lock button or pull the handle only on column mounted transmission shifters out. Some vehicles position transmission selector buttons for each mode on the cockpit instead, freeing up space on the central console. Automobiles conforming to United States Government standards must have the transmission modes ordered P-R-N-D-L (left to right, top to bottom, or clockwise). Prior to this standard, quadrant-selected automatic transmissions often utilized a P-N-D-L-R layout, or similar. Such a pattern led to a number of deaths and injuries owing to unintentional transmission gear selection, as well as the danger of having a transmission selector jump into Reverse gear from Low gear during engine braking maneuvers.

Automatic transmissions have various modes depending on the model and make of the transmission. Some of the common transmission gears and modes include:

Park (P): This gear selection mechanically locks the output shaft of the transmission, restricting the car or truck from moving in any direction. A parking pawl prevents the automatic transmission from rotating, and therefore the car or truck from moving, although the vehicle's non-driven road wheels may still rotate freely. For this reason, it is recommended to use the hand brake or parking brake because this actually locks the rear wheels and prevents them from moving in most cases. This also increases the life of the automatic transmission and the park pin mechanism, because parking on an incline with the automatic transmission in park without the parking brake engaged will cause undue stress on the parking pin. An efficiently-adjusted hand brake should also prevent the car or truck from moving if a worn transmission gear selector accidentally drops into reverse gear during early morning fast idle engine warm ups. It should be noted that locking the automatic transmission output shaft does not positively lock the driving wheels. If one driving wheel slips while the automatic transmission is in "park," the other will roll freely as the slipping wheel rotates in the opposite direction. Only a properly adjusted parking brake can be relied upon to positively lock both of the parking-braked wheels.

It is typical of front-wheel-drive cars for the parking brake to be on the rear non-driving wheels, so use of both the parking brake and the transmission park lock provides the greatest security against unintended movement on slopes. Unfortunately, the rear of most front wheel drive automobiles has only about half the weight on the rear wheel as is on the front wheels, greatly reducing the security provided by the parking brake as compared to either rear wheel drive vehicles with parking brake on the rear wheels which generally have near half of the total vehicle weight on the rear wheels, except for empty pickup and open bed trucks or to front wheel drive vehicles with the parking brake on the front wheels, which generally have about two thirds of the vehicle's weight unloaded on the front wheels.

A car or truck should be allowed to come to a complete stop before setting the automatic transmission into park to prevent auto trans damage. Usually, Park (P) is one of only two transmission gear selections in which the car or truck engine can be started, the other being Neutral (N). In many modern cars and trucks, the driver must have the foot brake applied before the automatic transmission can be taken out of park. The Park position is omitted on buses / coaches with automatic transmission on which a parking pawl is not practical, which must be placed in neutral with the parking brakes set.

Most car and trucks require P or N to be set on the selector lever before the internal combustion engine can be started. This is typically achieved via a normally open 'inhibitor' switch, which is wired in series with the starter motor engagement circuit, and is only closed when P or N is selected, thus completing the circuit when the key is turned to the start position.

Reverse (R): This engages reverse gear within the transmission, giving the ability for the vehicle to drive backwards. In order for the driver to select reverse gear in modern day transmissions, they must come to a complete stop, push the transmission shift lock button in or pull the shift lever forward in the case of a column shifter and select reverse. Not coming to a complete stop can cause severe damage to the automatic transmission. Many modern automatic transmissions have a safety mechanism in place, which does to some extent prevent but does not completely avoid inadvertently putting the car or truck in reverse gear when the vehicle is moving forwards. This mechanism usually consists of a solenoid-controlled physical barrier on either side of the Reverse position, which is electronically engaged by a switch on the brake pedal. Therefore, the brake pedal needs to be depressed in order to allow the selection of reverse. Some electronic transmissions prevent or delay engagement of reverse gear altogether while the car is moving.

Some transmission shifters with a transmission shift button allow the driver to freely move the transmission shifter from R to N or D, or simply moving the transmission shifter to N or D without actually depressing the button. However, the driver cannot put back the shifter to R without depressing the shift button to prevent accidental shifting, especially at high speeds, which could damage the automatic transmission.

Neutral / No Gear (N): This disengages all gear trains within the transmission, effectively disconnecting the automatic transmission from the driven road wheels, so the vehicle is able to move freely under its own weight and gain momentum without the motive force from the engine braking). This is the only other transmission gear selection in which the vehicle's engine can always be started.

Overdrive (D, OD, or a boxed D): This mode is used in some automatic transmissions to allow early computer controlled transmissions to engage the automatic overdrive. In these transmissions, Drive (D) locks the automatic overdrive off, but is identical otherwise. OD (Overdrive) in these cars and trucks is engaged under steady speeds or low acceleration at approximately 35–45 mph. Under hard acceleration or below 35–45 mph, the transmission will automatically downshift. Vehicles with this option should be driven in this mode unless circumstances require a lower gear.

Malibu LTZ, Corvette, GM trucks, Pontiac G8, Ford Falcon BF 2005-2007 and Falcon FG 2008 current in Australia with 6 speed ZF, and most newer model Ford, Lincoln, Mercury vehicles. However, seven-speed automobiles are becoming available found in Mercedes 7G gearbox, as are eight speed automobile in the newer models of Lexus and BMW cars and trucks.

Third(3): This mode limits the automatic transmission to the first three gear ratios, or sometimes locks the automatic transmission in third gear. This can be used to climb or going down hill. Some vehicles will automatically shift up out of third gear in this mode if a certain RPM range is reached in order to prevent engine damage. This transmission gear is also recommended while towing.

Second (2 or S): This mode limits the automatic transmission to the first two gear ratios, or locks the transmission in second gear on Ford, Kia, and Honda models. This can be used to drive in adverse conditions such as snow and ice, as well as climbing or going down hills in the winter time. Some vehicles will automatically shift up out of second gear in this mode if a certain RPM range is reached in order to prevent engine damage. Although traditionally considered second gear, there are other names used. Chrysler models with a three-speed automatic since the late 1980s have called this gear “3” while using the traditional names for Drive and Low.

First (1 or L Low): This mode locks the automatic transmission in first gear only. It will not change to any other transmission gear range. This, like second gear, can be used during the winter season, or for towing. As well as the above transmission modes there are also other modes, dependent on the manufacturer and model.

Some Other Transmission Modes Include:

D5: In Honda and Acura vehicles equipped with five speed automatic transmissions, this mode is used commonly for highway use and uses all five forward transmission gears.

D4: This transmission mode is also found in Honda and Acura four speed automatic transmissions or five speed automatic transmissions, and only uses the first four transmission gear ratios. According to the manufacturer manual, it is used for "stop and go traffic", such as city driving.

D3 or 3: This transmission mode is found in Honda, Acura, Volkswagen and Pontiac four speed automatic transmissions and only uses the first three transmission gear ratios. According to the manufacturer manual, it is used for "stop & go traffic", such as city driving.

S or Sport: This is commonly described as 'Sport mode'. It operates in an identical manner as 'D' mode, except that the transmission up shifts change much higher up the engine's rev range. This has the effect on maximizing all the available engine output, and therefore enhances the performance of the car or truck, particularly during acceleration. This transmission mode will also down change much higher up the rev range compared to 'D' mode, maximizing the effects of engine braking. This transmission mode will have a detrimental effect on fuel economy. Hyundai has a Norm / Power transmission switch next to the gearshift for this purpose on the Tiburon.

Winter (W): In some Mercedes-Benz, BMW and General Motors Europe models, a transmission 'Winter mode' can be engaged so that second gear is selected instead of first when pulling away from stationary, to reduce the likelihood of loss of traction due to wheel spin on snow or ice. On GM cars, this was D2 in the 1950s, and is second gear start after 1990. On Ford, Kia, and Honda automatic transmission, this feature can be accessed by moving the gear selector to 2 to start, then taking your foot off the accelerator while selecting D once the car is moving.

Brake (B): A transmission mode selectable on some Toyota models. In non-hybrid cars, this mode lets the engine do compression braking, also known as engine braking, typically when encountering a steep downhill. Instead of engaging the brakes, the engine in a non-hybrid car switches to a lower transmission gear and slows down the spinning tires. The engine holds the car back, instead of the brakes slowing it down. For hybrid cars, this mode converts the electric motor into a generator for the battery. It is not the same as downshifting in a non-hybrid car, but it has the same effect in slowing the car without using the brakes. GM called this HR (hill retarder) and GR (grade retarder) in the 1950s.

+ -, and M: This is for the 'manual transmission mode' selection of gears in certain automatics, such as Porsche Tiptronic transmission.. The M feature can also be found in Chrysler and General Motors products such as the Dodge Magnum and Pontiac G6, as well as Toyota's Camry, Corolla, Fortuner, Previa and Innova. Mitsubishi and some Audi models (TT), meanwhile do not have the M, and instead have the + and -, which is separated from the rest of the shift modes; the same is true for some Peugeot products like Peugeot 206. Meanwhile, the driver can shift up and down at will by toggling the console mounted shift lever like a semi automatic transmission. This transmission mode may be engaged either through a selector / position or by actually changing the transmission gears (e.g., tipping the gear-down paddles mounted near the driver's fingers on the steering wheel).

What Is Drive?

Drive (D): This position allows the automatic transmission to engage the full range of available forward gear trains, and therefore allows the vehicle to move forward and accelerate through its range of transmission gears. The number of gear 'ratios' an automatic transmission has depends on the model, but they initially ranged from three predominant before the 1990s, to four and five speeds losing popularity to six-speed autos, though still favored by Chrysler, Honda and Acura. Six speed automatic transmissions are now probably the most common offering Toyota Camry V6 models, the Chevrolet Malibu LTZ, Corvette, GM trucks, Pontiac G8, Ford Falcon BF 2005-2007 and Falcon FG 2008 current in Australia with 6 speed ZF, and most newer model Ford, Lincoln, Mercury vehicles. However, seven-speed automobiles are becoming available found in Mercedes 7G gearbox, as are eight speed automobile in the newer models of Lexus and BMW cars and trucks.
