Dexron III <> Dexron VI


Recommended Posts

Hi all

Does it mean you have to replace Dexron III with Dexron VI if the car still under warranty?

(In case you have to fill up or just replaced a gasket and have to refill ?)


So it is also not clear if you can mix the two Dexron even if the transmission filled up with Dexron III at the factory.

One of the links has text that definitely says that Dextron VI *must* be used in all transmissions and other equipment that previously used Dextron III, except some transfer cases and such. For anything other than a transmission, check with your owner's manual and/or dealer (have your VIN number ready when you call your dealer). But transmissions are unequivocal: for top-off, refilling, or flushing, Dextron VI must be used, and Dextron III must *not* be used.
