Pulled the pan on my tranny today. Just put a new pan and gasket on so I would have a drain plug which the old pan didn't have. The new one left a puddle under the car in jut one night. Never had a leak before! Arrgh!
Tossed the gasket and installed it again with Ultra black RTV. Hopefully it will stop the leak. I'll let it it overnight before refilling the trans so the RTV can set up first.
