Hello. I have a 1998 C280 w/90000 miles AT fluid leak. I?ve replaced
the pan gasket and filter because I had noticed small leaks on my
garage floor. Its still getting wetness around the seal near the pan.
I can?t notice it coming from anywhere else. Levels are properly
filled. Could replacing the pan itself be the next step to getting a
tight seal? It operates great, just trying to stop the leak in my
garage. Any suggestions?

Did you wipe it down very thoroughly? ATF can hang around for a while
once it escapes. If you resealed the pan, and did a nice careful job,
then that shouldn't be the problem.

How about the shift selector? Look where it enters the Tranny?

You have to clean it up like crazy and then WATCH IT and figure out
where the leak is.

There's no shortcut.

The wiring from the ECU where it enters the transmission (via a plug) is
also a favourite spot for leaks.
