Transmission to transfer case gasket - GM part number?

[mrweelr]

I want to replace the gasket between the transmission and transfer case before I put the t-case back in my truck. Does anyone know what the GM part number for this gasket is?

Thanks,

The seal is an o-ring type seal that goes betweenthe adapter and the tail section of the trans.

The gasket is a flat paper type gasket that goes between the x-case and the adapter.

If you are jsut swappingthe X-case then it is only the gasket you need.,
If you are swapping in a new trans and using your old adapter you will need both.

I always get them at the dealership. However, you can also buy some rubberized gasket material and use the gasket to trace a new one and cut with an x-acto knife.
