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.
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 suitable tool (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 assemb ly from reverse clutch drum.
CAUTION:
Do not remove return springs from spring retainer.
6. Install seal rings to drum support of oil pump assembly (1), and set reverse clutch drum (2). Then apply compressed air into the
oil hole at the location as shown in the figure to remove reverse
clutch piston (3) from reverse clutch drum (2).
CAUTION:
Do not flow air in too quickly or reverse clutch piston (3)
and ATF could jump out. Carefull y flow air in little by little
while protecting with lint-free cloth.

• Make sure that check balls are not fixed.
• Apply compressed air to check ball oil hole opposite from return spring. Make sure there is no air leakage.
• Apply compressed air to oil hole on return spring side to make sure
that air leaks past ball.
Reverse Clutch Drum Check for deformation or damage. Replace if necessary.
ASSEMBLY 1. Install D-ring (1) and seal lip (2) on reverse clutch piston (3). CAUTION:
