On mine, I was not able to remove the AVIAD pan with the motor in place, the rear would not clear the frame rails and crank at the same time. Was a real pain several times.

Tom Lucas (FE specialties) replaced my RMS once (it didn't leak afterwords),and I believe he had to move/lift the motor a bit to get the pan off. And he did it as described above: dropped the crank a bit, and slipped it on without removing the tranny.
