DexronDEXRON is a registered trademark of General Motors Corporation. Since the beginning of 2007, GM have only supported only the use of
DEXRON-VI fluids for use in Hydra-Matic transmissions; all DEXRON-III licenses expired at the end of 2006, and will not be
renewed. The
DEXRON-III licensing system therefore no longer exists so these fluids are not
regulated in any way, but we have categorised the oils that met the earlier DEXRON quality standards in the categories below.

The DEXRON VI specification (GMN 10060) defines both a performance level and
specific additives that provide improved shift feel, friction
durability and oxidative stability compared to earlier specified fluids. |
