Transmission leak from changing rear main seal? 900 1993

posted by  someone claiming to be sonnyjim on  Fri Jun 23 23:03 CST 2006 [RELATED]

I just had my rear main seal replaced to stop a pretty bad oil leak. Now I'm getting a quarter-sized spot of tranny fluid leak every morning. I had a complete re-seal done on the tranny just 2 yrs ago and haven't had to top off the fluid since. I just want to know the facts so I won't get screwed when I take it back. What seal did they probably mess up?

I agree with Steve, the cooler lines are a very likely suspect, especially since that's the connection which would have been removed when removing the transmission to replace your rear main seal.

The other possibility is that the tailshaft bushing and seal are shot- common to all AW70/71 transmissions and a likely wear item.

It can leak from the front seal, the lines, anywhere. You first need to locate the source of the leak. I strongly suspect it is leaking from the cooler line connections.
