I know this might seem a bitpicky - but, I don't want to screw this up - I have learned that type 4 auto transmission is the correct type to use in an "older Ford" - I own a 66/289 mustang with a C4 auto transmission and "power assist" steering- my original owners manual spec is calling for M2C33D - every type 4 that I have seen advertised says that their transmission fluid is compatible to spec M2C33F or G - can I use a type F if it calls for these letters and not the D? - why don't they include the D? - also, my owner's manual calls for the same spec transmission fluid to be used as power steering fluid - can I do this? - or should I use a good quality power steering fluid? - like Prestone All Milage, With Conditioner.

Thanks!

 

I use type "F" in my C6 and the FMX trannys in my stangs. I also use the same, type "F" in the power steering units. No problems here. Once in a while, I need to use a power steering seal conditioner to help with some of the minor leaks (found out that Lucas PS fluid works best here). If you are concerned then go with a high quality type F fluid like royal purple or amsol. I guess they sell type F.

 

Been using type F for yrs in my c4 and off the shelf power steering fluid from local parts chain or walmart with no ill effects.

 

Type F is sometimes difficult to find - but don't use anything but Type F.

I'n one of my tci streetfighter c-4's I use dextron III/mercon and have used it in others too...works great

 

Newer versions of the tranny fluid are compatable with older specs.

 

i use type F in my C4. i wouldntuse anything else like mentioned above, i dont have a problem finding it at local auto parts stores.
