Special Tools
- Inspect the check ball is free by shaking the coast clutch piston (221).
- Inspect the valve does not leak by applying low-pressure compressed air.
- Coat the overdrive clutch piston inner and outer seals (222, 223) with ATF and install them on the overdrive
clutch piston (224).
- Coat the inner surface of the overdrive and coast clutch housing with ATF.
- Press the overdrive clutch piston (224) in the overdrive and coast clutch housing (225), being careful not to damage
the O-ring.
- Coat the coast clutch piston inner and outer seals (219, 220) with ATF and install them on the coast
clutch piston (221).
- Coat the inner surface of the overdrive clutch piston with ATF.
- Press the coast clutch piston (221) into the overdrive clutch piston (224).
- Place the overdrive coast clutch spring (218) on the coast clutch piston (221).
Important: Be sure the end gap of the retaining ring is not aligned with the spring retainer claw.
- Using the bridge and legs of the

(3) with the forcing screw of the
J 23327
(2) and J 21420-2 (1) plate,
which is part of
J 23327
, compress the overdrive and coast clutch spring (218).
