shift shaft seal replacement

[Phill]

have replaced it twice and it keeps leaking. a friend said the shaft might be worn. any ideas or tricks anyone can suggest or does the shaft need replacing. the car is a 79 w/th350.

If you can get the shaft out (sorry not familiar w/ autos), check for scratches or nicks. Might be able smooth out w/ crocus cloth.

Are you talking about the rear output shaft seal on the trans? If so, I'm in the same boat as you. Been replaced two or three times now and starts to leak again after a few months. I even had the yoke looked at. Maybe it's time for a new one but I understand they are extremely hard to find as they are no longer made.

Nope, its the seal where the shifter cable goes hooked up to the transmission. your talking about the tailshaft seal.

Kind of a Bubba fix, but try putting an o-ring on the shaft before you install the new seal. You could also install 2 seals.

Wrap a piece of heavy paper around the end of the shaft- the flats have sharp edges and will nick the seal as it goes over them.

When i first replaced the seal the PO used silicone in place of the seal. that and a few other things lead me to believe his name was bubba or was related to bubba.

If there's any silicone stuck to the shaft that could be your leak. Make a rough spot.
