"The Dexron VI is backward compatible for all older transmissions so it would probably be good to use in the Fieros that have automatics."
Although Dexron VI maybe backwards compatible in some transmissions like those installed in the Fiero, it is not backwards compatible in all transmissions. The service spec for the Allison transmission in my motorhome specify Dexron III and states the new Dexron transmission fluids are not compatible. Allison has their own specification (TES 295) for synthetic ATF for their transmissions. Just read the specs before changing the fluids.
Yes, The statement from GM covers GM transmissions and some others. You have to check others.
Mobil 1, Valvoline and others No longer make DEXRON III only ATF. If you want/need DEXRON®-III or a MERCON®, they have "multi-brand" ATF like Mobil ATF™ D/M
|Mobil ATF D/M is recommended by ExxonMobil for use in applications requiring: |
GM DEXRON® IIIH transmission fluid
Ford MERCON® transmission fluid
Allison C-4 transmission fluid
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
