I had a tranny pan leak so decided to change out the gasket today. Dropped the pan, put on the new gasket and put everything back in. First of all, I added too much fluid as I thought it called for 8 quarts but after researching a bit it seems that 5 or 6 would have been good. But anyway, it seems to be leaking worse than before. Is there something wrong with my gasket or seating surface or are these gaskets not supposed to hold in excessive amounts of fluid. Not sure what the issue is and why I can't stop this thing from leaking!
