CLUTCH
(a) Place the oil pump onto the torque converter clutch, and
then place the O/D direct clutch assembly onto the oil
pump.
(b) Using SST and a dial indicator, measure the O/D direct
clutch piston stroke while applying and releasing com-
pressed air (392-785 kPa, 4-8 kgf/cm
2 or 57-114 psi).
SST 09350-30020 (09350-06120)

(c) Remove the piston return spring.
6. REMOVE OVERDRIVE DIRECT CLUTCH PISTON
(a) Place the oil pump onto the torque converter clutch and
then place the O/D direct clutch onto the oil pump.
(b) Hold the O/D direct clutch piston, apply compressed air
to the oil pump to remove the O/D direct clutch piston.
(c) Remove the O/D direct clutch piston.
HINT: If the piston is at an angle and cannot be removed,
press down on the side jutting out and again apply com-
pressed air, or else wind vinyl tape around the piston end
and remove it with needle nose pliers.
(d) Remove the 2 O-rings from the piston.
7. REMOVE RING GEAR FLANGE
(a) Using a screwdriver, remove the snap ring.
(b) Remove the ring gear flange.
8. REMOVE RETAINING PLATE

(b) Place SST on the spring retainer, and compress the re-
turn spring with a shop press.
SST 09350-30020 (09350-07040)
(c) Install the snap ring with SST. Be sure the end gap of the
snap ring is not aligned with the spring retainer claw.
SST 09350-30020 (09350-07070)
5. INSTALL PLATES, DISCS AND FLANGE
(a) Install the plates and discs.
Install in order: P = Plate D = Disc
P-D-P-D
(b) Install the flange, the flat end facing downward.
(c) Using a screwdriver, install the snap ring.
6. CHECK PISTON STROKE OF OVERDRIVE DIRECT
CLUTCH
(a) Place the oil pump onto the torque converter clutch, then
place the O/D direct clutch assembly onto the oil pump.
(b) Using SST and a dial indicator, measure the overdrive di-
rect clutch piston stroke while applying and releasing
compressed air (392-785 kPa, 4-8 kgf/cm
2 or 57-114
psi).
SST 09350-30020 (09350-06120)
Piston stroke:
1.45-1.70 mm (0.057-0.067 in.)
If the piston stroke is less than the limit, parts may have
been assembled incorrectly, so check and reassemble
