Casting numbers on top of the bellhousing flange and the suffix number on the block deck in front of the passenger side head. The casting numbers will tell you which block casting you have. The suffix will tell you what HP rating it had, what it was likely installed in, and what transmission was mated to it.
The automatic transmission housing / case is a single casting, so the bell housing cannot be detached separately.
Pull the torque convertor out, they are on the front of the tranny inside the bell housing.
It’s a 6L90E 6 speed GM automatic.
