TH350 external seals/gaskets
1 Attachment(s)
Good morning. Looking for a little help from the transmission gurus out there. I am cleaning up my TH350 to go back into my project. It was working well a year ago so I think the internal components are fine. Obviously there is a problem with some. Oil leakage (spent yesterday scraping crud, decreasing today). Hard to pinpoint the exact location. My question is which seal/gaskets should I change to cover all my bases? Was thinking input and output shafts, shift selector, oil pan. Anything else you would replace?
Thanks for the advice! |

I would replace the speedometer driven gear "bullet". They wear over time and leak.

Kick down cable and dipstick seals

If it were me in that position, I would replace pan gasket, tail shaft housing gasket, tail shaft slip yoke seal, modulator o-ring, dipstick o-ring, and speedometer o-ring. I think you can do all of these without much disassembly. New filter too. Probably get a good gasket kit and use the pieces needed.

looks like most of that came from the engine
