Diff Housing seal or gasket

I believe the seam between the Differential housing and the transmission is leaking on my 2001 GP with this 4t65e tranny. I am planning to remove the housing and inspect but I'd like to find a replacement "o ring " or gasket before I pull it off. I've spent some time trying to find one but I cannot. Can someone provide some insight on this ? Is it a gasket or an "o ring" and where can I get one? This is not an HD housing. I like to resolve this leak this weekend.
Thanks!
 


I have the seals here, it is a square cut oring. Send me an email if you dont have any luck finding one local but most trans shops should have them and even the dealer may have one but probably want too much for it. Shipping is going to cost more than the seal from me so you may want to consider that
 
Thanks Trannyman thats what I needed to know. I though I had seen a diagram with it as an o ring somewhere. There are two tranny shops in town here I will check on. Since I want to get this done Friday I'll check locally. Thanks again !
