Changing tranny filter for first time by myself. 1992 300D. New filter comes with one cork gasket on small hole and two on large hole. Do all three get installed, or does it depend on which transmission it's going on? What confuses me is I don't think I saw any gaskets come off the large hole on the old filter.

Thanks.
