Doing a rebuild on my C6 that will be going behind the 514 crate. Lower gears, new kit (clutches, etc), reverse valve body, blah, blah, blah. What tranny fluid do I need to use is this thing??? Does it make a difference what year the tranny is??

Thanks,
Chad

Zzzzzzzzzzzzzzzzzziiiiiiiip. (putting my flame suit on)...... Personally if you're going to use it in HARD racing situations, I'd recommend type F. My .002

hmmm, i seem to like B&M Trickshift. I don't race with a slush box, buy i had a 74 F350 dump that liked to smoke fluid. i tryed it and it did not burn up fluid for a year or so. It passed the high cost of cheap help test.

I looked at the B&M and damn$$$$$$$. Anyway, I have seen F, ATF, ATF+3, Dex III, etc, and even mobil synthetic F. do I use F or ATF or are they the same??? Help???

Use the Type F. I have had very good luck with Havoline Type F. Even run it in my Powerglide.

John Winters (of JW trans and converters) explained it too my like this:

Use type F for anything that has performance type clutches. The clutch material on these are actually softer, but they have more "bite". I confirmed this on my last rebuild. The new Alto red and Raybestos Blue Plate clutches were soft enough that you could scratch the material off with your fingernail. Plus I use a Kevlar lined band that is downright fragile. I could barely scratch the oem clutches or band. The soft material will lock up quicker and it can absorb the shock better. The Type F fluid helps as it is not a slippery as Dex/Mercon.

Any trans that has oem or std rebuild clutches use Dex/Mercon (Ford oem prior to 80 uses Type F also). The slippery fluid works with the harder clucth material. Dex/Mercon lets things slip a little more so Grandpa doesn't spill his coffee when his Lincoln changes gears. The factory wanted the smoother, drawn out (and slipping) shifts.

Later,

So is ATF the same as F?? Any suggestions as far as using a synthetic??
