ATF 4 Vs Dexron VI | Similarities and Differences
ATF 4 or ATF+4 and Dexron VI both are full synthetic automatic transmission fluids. The ATF 4 is engineered and developed for the Chrysler transmissions and the Dexron VI is developed and designed for the GM automatic transmissions.
However, both of them are similar transmission fluids but they have some differences in their composition. And here we are going to point out some basic similarities and differences between ATF 4 Vs Dexron VI.
Hopefully, after reading this article, you won’t have any confusion about these two transmission fluids. So let’s get started by knowing the basics.
What is ATF 4?
ATF 4 is a transmission fluid trademark used by Chrysler that is specially designed and developed for the Chrysler transmissions. This is a synthetic automatic transmission fluid that comes with special type additives to increase the transmission performance as well as increase its lifetime.
ATF 4 also known as ATF+4 and ATF+, ATF+2 and ATF+3 are some previous versions of this fluid. All the ATF+4 currently available in the market (from Mobil, Pennzoil, etc.) are meets the Chrysler Material Standard MS-9602.
What is Dexron VI?
In 2004, GM released the Dexron VI which is the upgraded version of the Dexron III transmission fluid. This is also a synthetic automatic transmission fluid that is specially engineered for the 6-speed GM automatic transmissions.
The viscosity level of this Dexron transmission fluid is a little lower (6.4 cSt at 100 °C) than the previous Dexron III. So it helps to increase the transmission performance, seal the leakage and increase the durability of the transmission.
ATF 4 Vs Dexron VI
The main difference between ATF 4 and Dexron VI is that ATF 4 is designed for the Chrysler automatic transmissions whereas the Dexron VI is designed for the GM automatic transmissions. Although both of them are synthetic transmission fluids, but the ATF 4 comes with special type additives for better performance.
Compatibility
ATF 4 is mainly compatible with the Chrysler transmission but they can be used on other automatic transmissions. The specialty of this transmission fluid is its additives. 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
The price range of both ATF 4 and Dexron VI is almost the same for several brands. But for some brands, ATF4 is a little bit pricy than the Dexron VI. However, it’s good to use ATF 4 if your car manufacturer recommends using it.
Related Questions and Answers about ATF 4 and Dexron VI
Is ATF 4 Compatible with Dexron?

Is ATF+4 Synthetic?
Yes, ATF+4 is a full synthetic automatic transmission fluid that is made according to MS-9602 Fluid Material Standard.
Can I Mix ATF 4 and Dexron VI?
Yes, as both of them are synthetic automatic transmission fluids, so you can mix them. But for the better ATF4 performance, it’s not a good idea to mix it with Dexron VI.
Is Dexron VI Compatible with ATF+4?
Yes.
ATF+4 Vs Dexron III
The main difference between ATF+4 and Dexron III is that the ATF+4 is a full synthetic transmission fluid designed for Chrysler transmission. And the Dexron III is a conventional automatic transmission fluid that is engineered for the GM pre-2005 automatic transmissions.
Final Words
It is always important to use the right type of transmission fluid according to your vehicle’s user manual. This will help to get the best transmission performance as well as keep the transmission condition good for a long time. So either ATF 4 or Dexron VI, use the specific transmission fluid that recommends by your car manufacturer.
