I have TH350 tranny that leaks after a drive when car is off. Filler tube is sealed and kickdown cable is connected. Any ideas?. Thanks.

 

Where exactly is it leaking from? Have you tried looking underneath to try and pinpoint the spot or is it just to hard to find an exact spot?

 

TH350's like to leak from the selector shaft seal. Sometimes guys will change the seal but not the bushing and it still leaks.

 

[X(] the pan gasket is often a culprit, the gasket hardens or compresses over time and sometimes just needs to be tightened up or replaced if its time to service it anyway. selector shafts and tail shafts are other common leak areas youll have to wipe it down and watch to determine its exact location kurt

 

I think it is coming from the pan gasket. I tightened the bolts so we will see what happens. Thanks for all the help.

 

Found the leak coming from the filler tube. I tried a few different o rings but its still leaking. Any ideas?
