The Cometic AFM transmission oil pan gasket for GM Turbo 400 (.075") is built from a chemically blown nitrile rubber bonded to an aluminum core to provide strong torque retention and temperature resistance. AFM material recovers substantially under load, creates an excellent seal between pan and block, and does not require sealants or re-torquing, offering dependable oil pan sealing for transmission service applications.
