The Cometic AFM transmission oil pan gasket for GM 4L80E (.060") uses a chemically blown nitrile synthetic rubber bonded to an aluminum core to seal the oil pan. AFM material offers about 85% recovery, strong torque retention, and temperature resistance above 205°F. The gasket is designed to seal without additional sealants or re-torquing, simplifying installation and long-term sealing performance.
