Should I rebuild this c-4?

Five0 · 06-29-2001, 11:44 PM

I just got a c-4 transmission and it has been sitting out in the weather in a mustang with no motor and no converter attached.

The guy I got it from said that it was rebuilt about 3 to 4 years ago and he put about 500 miles on it.

I got the thing for free and he said he recommends refreshening it.
It has some rust on the input shaft.
The c-4 has an H servo and a reverse manual valve body.

Do you think after sitting so long that it would be all right to run or do you think I should rebuild it and why?

The guy that built it the first time said he will do it for $300.00, is that a good price?

The torque converter I have is a TCI street fighter. Is this a good converter?

Did it have the dipstick tube in it? That's the most important part. I've found spider nests in trannies with dipsticks missing. I wouldn't worry much about surface rust on an input shaft. That's hardened steel, pretty tough to corrode really. Freshening it up will probably save you a lot of leaks down the road, plus you'll know exactly how it's built inside. Don't tell me a C4 is difficult to rebuild, they're cakewalk compared to anything else!

$300 ain't too bad considering a rebuilt kit itself is around $100. IMHO, TCI converters are complete garbage. I've been burned twice by TCI products and will never trust their stuff again. It's B&M for me, and I've always been 100% satisfied with their products.
