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.
