Classic/Antique Car Repair: Transmission pan gasket, pan gasket, bolt holes

Question
Hello
     I have a 1972 Plymouth Fury with a A727 Tranny.
Pan gasket leakes,have changed it twice,still leaks.
Have tried gaskets with and without gasket sealer.
Pan is not bent,I'm going nuts what can I do.
Thank You
Les

Answer
It is either bent, has a hole in it or there is something above it leaking and running down to the gasket mating surface appearing to be the pan. The most common cause of a pan gasket that continues to leak is from overtightening the pan at some time or other. This draws the metal up around the bolt holes and when installed leaves a slight gap between the bolt holes. This can be corrected using a hammer and a straight edge.
