If you are going far enough to change the cork gasket, I'd get a set of damper springs and pins for the hydro. You may have to do a "trunion repair" also. Check your driveline while you are at it--may need new rubber discs/couplers. There is a lot of work just to change the gasket, you can do all the other while you have it apart with not much more work.
