Replacing front pump seal on TH350 Transmission

Postby onespeedyrc on Wed Apr 25, 2012 4:59 pm

How much of a pain is it to replace the front seals on the a TH350 Transmission? Dropping it shouldn't be a problem, I just wonder what can of worms I'd be getting into. From the diagrams I have it looks like there is a seal behind the torque converter in the center of the pump housing, and a larger one on the pump housing. Looks like this just unbolts and slides out or is there more to it? Seems that since this car sat for 3+ years in storage, more and more leaks are cropping up. I'm going to replace the fluid and filter, any other seals or gaskets that I should look at since the trans will be out of the car? Change modulator or any other parts? Any advise is greatly appreciated!

I would do the front and rear tranny seals...as well as checking your rear main oil seal while the tranny is out.
