|LanceM||Don't want this to sound like anything other than a question, but did you put the seal in the right way? If you put it in backwards it will leak, don't ask how I know.....|

thanks for the info... I believe there were a bunch of posts about proper yokes with or without holes and if they mated up to the wrong tranny there would be an issue... I think Im recalling it correctly. I'll have to check that out. I'd hate to mess with the drive train after actually being happy with the setup.
Yeah the color is cool, I bought the truck with the body work done, it has some pearl in it so it really kicks at night and sorta has a deeper look under different artificial lights.
I reallize this is slightly off forum topic, but here's my paint codes given to me by the guy who painted the truck in case anyone is interested...

th350 rear seal leak
I have a '77 and have had the same problem - I bought a 700 R$ and replaced 3 new seals and checked the run out. All was OK. It still leaked. The TCI guy ( sold me the 700R4) said the check my yoke. I didn't believe him but I just took it off and it has a small hole in the center of it!!!! The shaft seal is dry. Maybe you should check yours too. I amgoing to eposy the hole and see if it leaks too.
Good luck. Bill77C10
BTW - nice color on your truck- mine is almost exactly the same shade of blue -a custom Sikkens Color - go figure.

Seal Leak Saddness
ANY recommendations on a good tranny book would be appreciated. I don't mind reading/learning. I guess I was being hopeful that replacing the seal was going to fix my problem and it did not. Other than that, I like the 350turbo. Lots of Giddy Yup.

Did you check to see if there were grooves worn in the slip yoke?
If so, either a repair sleeve can be installed (if you can find one) or a new yoke is in order.
If the yoke is OK, did you happen to apply a small amount of transmission fluid to the surface of the yoke, and inner surface of the seal?
If not, you could have prematurely worn the seal.

when you removed the output shaft flange did you check wear the seals runs to see if there were any tram lines i,e worn flange
was the flange a good fit on the splines i.e tight or loose ?

T-350 rear seal leak
I have a th350 in my 69 gmc with a 350 ci motor. A few months back I notice tranny fluid leaking from the rear seal. I replaced the seal. After a few days it started leaking again. I figured maybe since I hadn't replaced the bushing at the same time that that was possibly the problem.
So I took off the tailstock of the tranny and replaced the bushing and the seal. Reassembled, and again I have the same leak.
With the truck sitting up it still manages to drip leak, suffice to say I'm not driving it AGAIN since I don't want to fry the tranny.
Is this a symptom of a bearing on the output shaft or something... my manual glances over alot of trannys and doesn't get specific enough for me to know if it is the problem AND if it is difficult to fix without investing in a special set of tools.
Is it worth the trouble fixing? Should I think about slapping a different tranny in to get better gas mileage?
Any advice would be appreciated!
