1. Check operation of reverse clutch
a. Install seal ring onto drum support of oil pump cover and install
reverse clutch assembly. Apply compressed air to oil hole.
b. Check to see that retaining plate moves to snap ring.
c. If retaining plate does not contact snap ring:
●D-ring might be damaged.
●Oil seal might be damaged.
●Fluid might be leaking past piston check ball.
2. Remove snap ring.
3. Remove drive plates, driven plates, retaining plate, and dish
plates.
4. Set Tool on spring retainer and remove snap ring from reverse
clutch drum while compressing return springs.
●Set Tool directly over springs.
●Do not expand snap ring excessively.
