Trans Help!

[nolidnoworries]

OK just dropped the pan on my recently rebuilt th350 and it full of black sludge. There are fine metal fragments in there too. It would not move when I put it in drive but reverse seemed to work fine. But I also noticed the cable going from the carb to the trans had came off too (the one with the orange clamp in pic). IYO which is the likely culprit, internal damage or this cable just wasnt hooked up?

That would be clutch material and the cable not being hooked up had nothing to do with the failure. On a TH350 the cable is a kickdown cable unlike a 700R4 which is a TV cable (throttle pressure).

ah got it thx, is that normal for a recent rebuild? i dont even think it has 100 miles on it yet. I bought the truck that way so im not 100 percent sure but the trans is spotless so it cant have been in there long.

Someone may have rebuilt the trans but never flushed the trans cooler and now all the crap from a previous explosion that was in the lines and cooler have ruined this rebuilt trans. This is just my speculation. It could also be that someone rebuilt the trans but used the same convertor from the bad trans on the rebuilt unit and that will wipe out a fresh trans as well.

That's really, really bad for a trans that has supposedly been rebuilt recently.

I've changed lots of trans fluid/filters and that's probably worse than any I've seen, even ones that hadn't had the pan off in 100K+.


I'd bet money that there's an internal failure that is causing this debris and the loss of forward gears.
