Dexron II vs Dexron III

[GH1]

My service manual calls for Dex II but it doesn't seem to be readily available, can Dex III be used? What about Dex/Merc?

Essentially it's just coolant / antifreeze though.

No it's not, it's ATF.

Sorry, brain freeze.

Dexron is the trade name for a group of technical specifications of automatic transmission fluid created by General Motors (GM). The name is a registered trademark of GM, which licenses the name and specifications to companies which manufacture the fluid and sell it under their own brand names.
