DEXRON III transmission fluid is a type of automatic transmission fluid used in General Motors vehicles. It is also recommended for use in other makes and models of vehicles.

If you are looking for a DEXRON III transmission fluid equivalent, there are several products that you can choose from.

By the end of 2006, all DEXRON-III licenses had run out and would not be renewed. After that date, General Motors will only support the use of DEXRON-VI fluids.

Is DEXRON 6 Compatible With DEXRON 3?

The expiration of DEXRON-III licenses in 2006 has led to many questions about the compatibility of DEXRON-VI fluids with DEXRON-III fluids. The answer is yes; DEXRON-VI fluids are compatible with DEXRON-III fluids.

DEXRON-VI fluids can replace DEXRON-III fluids in any vehicle that requires DEXRON-III fluid, including all GM vehicles manufactured after 2006.
