Replacing transmission

[orangeGMC]

I am going to be swapping out my TH350 for a rebuilt one. I would like to know if there are any gaskets that go between trans/engine and trans/adapter and adapter/transfer case? I have a 350 with TH350 to NP203. I don't want to get my hole project held up over something as simple as gaskets. Also does anybody have a parts breakdown diagram?

there arent any gaskets between the motor and trans i know for sure but not sure if there are between the adapter.

Technician a says

there is a gasket between th t-case and the adapter plate- some guys use silocone, there is an o-ring that goes in the back of the transmission and the adapter plate and nothing between the engine and transmission.

Do you know if local parts stores would have these? Or part numbers?
