I have an 8.1 liter Suburban and it's a 3D puzzle to take the pan out of the truck and then replace it. No, it is not simply removed from the transmission. It has to be moved (and rotated) around heat shields and exhaust pipes. This is not fun. This gasket retains its shape in all positions required for its final placement. job title. The metal inserts ensure that the seal is properly compressed and that the pallet does not deform during the clamping process. This job would become a mess with a flexible rubber or cork gasket. Good job Delko!
