Trans Leak!!!

I have a transmission leak at the tail shaft. I have replaced the the seal twice and still after sitting a couple of days it leaks. My Question is I believe I read on here somewhere (and I cant find it) that there is a difference in a 350 turbo yoke and a 700r yoke, i think it said that the 350 yoke has a hole right thru the center of it and that a 700 does not. Can anyone confirm this my yoke definitely has a hole in it. Any help would be greatly appreciated. By the way I am running the 700r

Re: Trans Leak!!!

I had replaced the o-ring and all on my TH350, and after a few months it started leaking again. I brazed it shut.

Re: Trans Leak!!!

Could be the tail shaft bushing is worn out.
