Leaking issues in my 200 4R - any gurus available?
Hey there fellow 2004R swap guy!! As far as I know fluid will only burp out of the top vent if the tranny is over filled. But the rubber seal on the dip stick tube can give you a leak in front on the passenger's side. Have you tried wiping it down real good and clean/dry then when it does leak find the source of the leak by tracing the flow to it's origin? I've never had a problem with any pan leaks and I never used any silicone or anything on the gasket. The pan could be bent around the bolt holes if you over torque a factory pan. Most of the after market pans have heavy rails and don't bend/distort very easy.
Sounds like an annoying problem:banghead:.
