Dave, EPDM rubber is not suitable for use with petroleum products. The ATF has likely degraded the rubber. Nitrile rubber would be a better choice.

The leak appears to be coming from the pan gasket. I used 1/8" EPDM rubber instead of cork because the cork always weeps. Now I don't understand why the EPDM is leaking, maybe too soft or too thick. What have other people used? Dave Sontos 02573 Great time at DCS. We are looking at the auto train from Washington for the Orlando 2012 event.
