I was gonna say shifter. If the fluid cooler lines are nearby they might be dripping down too.

It just may be. Will the trans have to come out to replace it?

That's encouraging! What holds the shaft that goes through the seal in? I believe that needs to be out so the seal puller can be used. Right??
