I've gotta say TH 400 because I've got two of them. One in the truck, and one in storage for when the first one blows up .

The 727 i had behind a 318 was the bigest slipping only had reverse when it flet like wast of space tho that 318 was a joke as well . . . about as useless as the 302 fords and 350 chevy's . . .

I vote TH400.

I don't like the TF727 cable kickdown and the fact the bands have to be adjusted. No bands to adjust in the TH400.

I do think the TH400s tend to leak more. However mine still seems to run fine 3-4 quarts low!

Still standing firm on the TH-400 over the TF-727 but you know it all depends if your a Mopar or GM person, now if your a Ford person I would go C-6 would be Fords competitive equal !

AAAAACCCKKKK! ZOMBIE THREAD!!!!

I'm an AMC convert from the Mopar camp. I've rebuilt four TF727s and four th400s, but I am not a trans guru like gsmikie (who is banned?). I have run Powerwagons and Ramchargers for years and most of my FSJs had TH400s. I like to rebuild TH400s more. For some reason, the oil pump is always a PITA on the 727s, some pieces are a little trickier to stuff in the case and little things like that. I don't have any dyno cards or nothing to show it, but my butt dyno says the 727 doesn't suck as much power. Rebuilding 400s always seems to go smoother, and somebody ALWAYS has the parts for it in town, the 727 I sometimes have to order a planetary set or sprag clutch then wait two days.

It's been said and I agree, having run both, I say they are equal.

TH400/TF727/C6 are the top 3spd automatic transmissions, after that Allison rules the auto trans world ;-) ! ! !
