Moroso transmission pan gaskets are manufactured from 40 Durometer rubber that’s molded over and vulcanized to a rigid steel frame. They allow for the quick removal and installation of transmission pans, requiring no removal of sealant, making them cleaner and easier to use. The extra-strength Moroso transmission pan gaskets will not leak, blow out, or get sucked in like stock or inferior-quality aftermarket gaskets. At a full 3/16 in., the Moroso transmission pan gaskets are guaranteed to outlast cork or rubber composite designs.
