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

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.

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,

David Cole
