In many new automatic transmissions, it is common to have clutch pistons that are known as molded or bonded rubber. In these cases, the entire piston needs to be changed, instead of just changing the seals on your piston during an overhaul. At Oregon Performance Transmission, we do carry full sets of molded pistons for all makes and models. If you need individual pistons we do carry these as well. Browse below through our complete selection of parts. For many applications, we are now carrying the new high performance blue pistons. The blue material bonded pistons work for all uses and do handle higher temperatures than the standard black rubber counterpart.
