Here is some pics of the case for my soon to be 6 speed 4L80E, first as I got it from the trans guy, basically lopped off with a plasma cutter and "Cleaned up" with a die grinder:

I cleaned up the casting snots on the top of the case because they were provoking me:

Had the machine shop throw it on the mill and clean up the front to make it even and parallel:
