Oil Pan Gasket, 700R4/4L60E (1983-UP) Cork

These are cork gaskets. With my 30 years experience with transmissions they seem to prevents leaks best. GM Transmission Parts did a great job with the shipment packaging. It prevented them from being folded. Other companies have folded them and this makes them take on a memory of the fold making them difficult to deal with. Thank you GM Transmission Parts for the great product, packing and the super fast shipping.
