The Dexron family of automatic transmission fluids is one of the most common ATFs on the market. Dexron 3 and Dexron 4 are two members of this family. So, what’s the difference between them?

The most significant difference between Dexron 3 and Dexron 4 is that Dexron 4 contains more additives than Dexron 3. These additional additives help to improve the overall performance of the fluid and provide better protection for your transmission.
