Ok, I recently rebuilt the tranny in my car, and everything operates good, but I've run into a little problem. I don't have any leaks. It's strange enough that the tranny isn't leaking, not even the tailshaft seal, but the rear main seal isn't leaking either, which is just mind boggling. I know the motor has oil in it, and I know I put fluid in the tranny, so what could be wrong?
