C4/C5 Premium Pan Gasket
Farpak is used by most professional transmission shops. If the pan comes off, a new gasket should go on. It's simply a fiber/neoprene composite gasket, not a true reusable like a silicone w/steel core. If you want it to last longer, you could apply some light grease or TransGel to the surfaces, which should reduce the sticking.
Farpak is miles ahead of a cork gasket for an automatic transmission.
