So I pulled the trans and bell housing. This bell housing zig zags on the passenger side like this:

So, looks like the bell housing gasket is not wide enough for the 1438 bell housing to seal all the way. In the picture below the black part of the gasket was exposed to outside while the copper part was mated. So when cool it didn't leak but once warmed up it would drip. I'm thinking its time to ditch the paper gasket and make my own using RTV.

The engine has a rear main seal. The transmission has an input shaft seal. I am under the impression that the bell housing is merely an adaptor from the engine to the transmission, and does not contain lubricant. Therefore a gasket is unnecessary. Am I mistaken?

I'm pretty sure the back of the bell housing sees the same level of oil as the rest of the transmission.
The oil will flow through the bearings and in the photo above the hole to the right of the bottom most stud goes clear through into the trans.
