Protrans Fluid
 

What type of trans fluid does ProTrans recommend for their MoPar 904 trannys? Also has anybody seen a performance gain using synthetic fluid over non-synthetic? Jim

Pro Trans recommends half Type F

Dave told me straight Type F. 904 all aluminun straight cut..... I'll check @ Vegas and edit my post if I'm wrong again.

I got my ProTrans from Joel's on Joy, in Detroit and was told to use Type F, No synthetic's at all ! The Smiths have also said the same ! Mine have been perfect, in the SS and the Stk 'r........John

I have only used type F in mine, FYI, I believe type F is being phased out and being replaced by type FA. I have bought all the type F I can find ...

What is the difference in type F and type FA ? Jim

My trans man told me I should run Mopar + 3 (likely now +4) in my 904 when I ran it a few years back. Surely not a ProTrans, but a slightly worked 904 with a Dynamic converter. He said the +3 had a better friction coefficient. I think that is also why Type F is recommended.

Sounds like the FA should work...no?

I totally missed the SS/F - SS/FA joke part of your answer. I though it was actual tech speak...
