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.
