my governor cap has a slow leak on it. instead of getting a new seal for it would i just be able to pull it off, take out the o-ring, and then use RTV on it to seal it? none of the local stores have the seal for it. i am hoping this will be a good substitute or not.

Pro Built Automatics

The o-ring can be found in any transmission shop or ask the parts man at the auto parts store for one that fits a TH350, as they always used a o-ring type of seal and the 700R4 did not. If you want to use silicone, use the type that works with transmission fluid. The RTV type does not work here.

i just had my governor cover off yesterday. i was surprised to find no o-ring. the rebuilder used sealer instead. they also didnt use the square cut o-ring on the tailhousing. i know it was leaking there. that o-ring i found at o'reilys auto parts. the governor o-ring i had in a re-calibration kit.
this tranny has had a mystery leak for a long, long time. when i keep finding that they didnt use o-rings, i understand why.

For the ultra black silicone it says it can be used for transmission pans. So I would guess it could work for this cap.

DID YOU finally fix the leaking fluid under the car. Was it the Pan? gasket ? or dip stick tube? Or Shaft seal ?
