Installation
6-friction drum: remove the cushion spring that rides on the apply piston. Start with the steel plate, then an externally splined friction plate lining up, then an internally splined friction plate lining up. Keep alternating and end with an internally splined plate; every friction plate faces lining up (7 internal and 7 external plates). Install the pressure plate and snap ring.
7-friction drum: remove the cushion spring. Start with an externally splined friction plate lining up, then an internally splined plate lining up, and keep alternating, ending with an internally splined plate; every friction plate faces lining up (9 internal and 9 external plates). Install the pressure plate and snap ring.
Pre-soak the frictions for at least 30 minutes in the ATF type the OE recommends. Clearance is checked between the pressure plate and the top friction plate in 3 places.
