I am completely stumped on my 727 transmission. I cant get the pan gasket to stop leaking. I have redone it about 8 times now. I have tried rubber and cork gaskets, silicone, permatex #2, and permatex HiTac. I have tried a brand new mopar pan and I am torqueing the bolts correctly with a torque wrench at 150 inch pounds. This last time I used permatex HiTac and a thick cork gasket and let it set for a week. I filled it up and it didnt leak. I ran the car for 15 minutes and the pan now leaks on two sides. I have looked at the flange and cant see any cracks, and it will leak in different places on the gasket depending on further tightening. Any ideas please ??
