1. Check operation of reverse clutch
a. Install seal rings to drum support of oil pump assembly, and set reverse clutch assembly.
b. Apply compressed air into the oil hole at the location as shown
in the figure.
c. Check to see that retaining plate moves to snap ring.
d. If retaining plate does not contact snap ring:
• D-ring might be damaged.
• Seal lip might be damaged.
• Fluid might be leaking past piston check ball.
2. Remove snap ring (1) using a flat-bladed screwdriver A.
3. Remove retaining plate, drive plates, driven plates and dish
plates.
4. Set Tool A on spring retainer assembly, and remove snap ring
(1) from reverse clutch drum while compressing spring retainer
assembly.
CAUTION:
Set SST directly over return springs.
5. Remove spring retainer assembly from reverse clutch drum.
CAUTION:
