This helps to lubricate the gears and belts perfectly that helps to run the transmission smoothly. Also, it helps to increase transmission durability.

Dexron VI is a widely used full synthetic ATF which is originally developed for the GM automatic transmissions. This fluid is also compatible with a wide range of automatic transmissions and you can also use it where Dexron III is used.

Function

Both transmission fluid functionality is also the same. They run the transmission smoothly, improve friction stability, and help to improve performance and durability. These fluids lubricate the gears very well for smooth shifting and prevent clutch damage.

Price
