d. If retaining plate does not contact snap ring:
 D-ring might be damaged.
 Seal ring might be damaged.
 Fluid might be leaking past piston check ball.
2. Remove snap ring (1) using suitable tool (A).
3. Remove retaining plate, drive plates, driven plates and dish
plates.
4. Set Tool on spring retainer assembly, and remove snap ring
from reverse clutch drum while compressing spring retainer
assembly.
