Hey everybody
Is there another seal inside the tail housing of my powerglide that would be causing it to leak fluid between the yoke seal and the yoke. I've replaced that seal and it has managed to make a little puddle over the winter.
I didn't have this problems until I got a new driveshaft made. The new yoke had a vent hole which it leaked from, so we plugged it. That slowed things down but fluid still escaped around the yoke. I figured I needed to replace that yoke seal...but apparently that was not the fix.
Thanks

Re: Powerglide tail housing leak
No, the only seal in the tailshaft is the one you see at the end. I would be checking the tailshaft busing inside the tailshaft, if they get a little worn or egg shaped form your original driveshaft being out of balance, it can cause the seal to leak. I actually had one on my th400 spin, come out and slide down the yoke causing the seal to leak. I would of never knew it came out until it started leaking. It is a easy fix and easy to check, remove the driveshaft, then the tailshaft housing and inspect and/or test fit the yoke inside, it should be snug and not wobble around. The yoke should not be scored either. A new bushing and seal are only a couple of bucks and you should be able to pick one up from any good parts store.
I am not really sure what the question is, but I am pretty sure the answer is Big Block.

Cool thanks, it's a pesky little leak that has been driving me nuts.

Re: Powerglide tail housing leak
I just went through this with my glide.
I replaced the tail shaft housing seal and then I did few other things, one put the tail shaft housing on our belt sander and trued up the end (going to the case).
Then I realized I also installed the O-ring the wrong way.
I put it on the housing first and then slid it on, but I was told to slide the O-ring over the output shaft support first, then put on the housing.
I also used some Loctite 592 on the bolt threads.
So far, no more leak.

Those who think they know it all have no way of finding out they don't.........
