NP 205 trans adapter question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is there supposed to be a gasket between the transmission and the T case adapter on a NP205 with a turbo 350? Took mine apart today to replace the coupler seals and install a fresh built t case and noticed there was no gasket there before and it looks like it might have been leaking.
Anybody have any idea?

I believe there should be one

I have a TH400 bolted to an Advance adapter and it has a gasket between the tcase and the tranny.

There should be a square cut 'O' ring between the 2

I went back out and looked in the oil pan I had under the back end of the transmission and there it was, the square cut o ring! Now the next question is can that o ring be bought at a parts store or is it going to be hard to find?

Thanks guys
