C6 1977 ATF

My C6 -77 Dipstick shows ESP-M2C138-CJ. What kind of ATFshould I use? Dexron II ?
Thanks!

You may wish to try searching for this via the search bar at the top of the forum. It's been beat to death a million times.

I tried but it was almost impossible for me to analyse all answers. I found a lot of different opinions, even answers
like " I have always used Type F in all my aut transmissions without any problems".
That's why I would appreciate some direct answers here. Thanks!

In general, I would suggest that if you see someone contradicting all the rest of the answers with "I've done that for years, no problems" - who are you going to believe, Ford engineers or someone you know nothing about? Me, I figure using stuff compatible with factory specs has kept my truck alive 40 years. Use the Dexron. I think anything compatible with Dexron III is compatible with II. But, I'm just another anonymous guy on the internet!

M2C33-F = F TYPE; M2C138CJ = Dex/Merc

C4 & C6 used type F thru 1976, Mercon from 1977.

Type "F" will typically give you firmer shift. "I've used it for years" in C6 trannys and power steering systems

Being that the C6 was never upgraded with better clutches Type F is generally the better fluid. FYI Mercon was phased out a long time ago so don't accidentally put the wrong fluid in. Most bottles say not for use in applications requiring Type F and this warning extends to the C6 also. You can still readily get Type F.

Nope, you want a low to zero friction modified fluid. I suggest type F.
