I moved the cross member and got the pan off today. It had a cork gasket that my friends probably put on when they helped me with putting this transmission in. In my opinion this was supposed to happen. The transmission was used with 55,000 miles on it. It came out of a Cadillac, that had been sitting a while. The pan had a bit of sludge in it, so needed to be cleaned. I've changed the transmission filter and cleaned the pan. I hope to get it mounted on tomorrow.
