im having difficulty finding the correct seal for a 00 jimmy 4wd. automatic transmission, extension housing seal,i removed the seal and discarded it. All parts stores are giving me the wrong seal. Anyone go through this before when replacing this seal? Anyone have a part number on this seal?

 

I use this site when I need a good exploded parts diagram and a GM part number. https://nemigaparts.com/cat_spares/epc/chevrolet/54s-t/

 

ill check that site and post all progress!

 

If the seal you are talking about is the paper seal between the tail housing and transfer case, nobody in my town had it and I didn't want to wait for prob. the wrong one to be ordered in.
I made my own. with the lost art of tapping out a gasket using bulk gasket material and a small ball peen hammer
