4L60E Rear Seal Question
For you A4 gurus, I have just put a shift kit, Yank 3000 converter and other Sonnax parts, plus a D44 in my '95. The trans has just over 50k on it. Should I change the tailshaft seal even though the original one doesn't leak? Is there a trick to installing the new one, or do you simply install it like any other seal? I don't want to cause a problem where none seems to exist.
Thanks for any help!

Re: 4L60E Rear Seal Question (AJR)
It should be real easy to replace the seal if you have a seal puller (looks something like a claw hammer). Just be careful not to damage the sleeve bearing that supports the drive shaft , when you remove the seal. Simply drive the new one in , being careful not to distort the seal. There is a seal driver tool that makes it easy , but not required if you are careful.
I wouldn't change the seal if it's not leaking with just 50,ooo miles. It's your choice either way. :cheers:

The trans is in? The 44 is in? And it's all buttoned up? No way! No one knows better, what is involved than YOU. Besides, remember what they say about what, "ain't broke".

The trans is in but the C beam and the rest of the drive train are not in yet. Car is still up on jack stands.
I appreciate the insight. I agree with "if it ain't broke", but I'm not a trans expert and I have no feel for the life of these, so I bought one just in case. I would rather not change, but didn't want to put it back together and have it start leaking in 10k.
I had evidence of a slight leak when I tore her apart, but it looked like it was coming from the VSS, not the tailshaft, so I replaced that "O" ring.
Anyway, thanks for taking the time to reply. I welcome everyone's input.

Re: 4L60E Rear Seal Question (AJR)
Since it's not buttoned up, yet, we're back to the original question. IF you decide to do it, do it right. Pull the tailshaft housing and replace the slip yoke bushing. Also, inspect, and polish or replace the slip yoke if it has a groove worn into it from the old seal. Since it isn't too late, it would probably be the smart thing to do.
