TORQUE CONVERTER CLUTCH
AND DRIVE PLATE
INSPECTION
1. INSPECT TORQUE CONVERTER CLUTCH
ASSEMBLY
(a) Inspect the one-way clutch.
(1) Set SST into the inner race of the one-way
clutch.
SST 09350-32014 (09351-32010)
(2) Install SST so that it fits in the notch of the
converter hub and outer race of the one-way
clutch.
SST 09350-32014 (09351-32010, 09351-
32020)
(3) Stand the torque converter up and turn the
SST.
Standard:
If the one-way clutch is turned clockwise,
it rotates freely and if turned
counterclockwise, it locks.
(b) Determine the condition of the torque converter
clutch assembly.
(1) If the inspection result of the torque converter
clutch assembly satisfies the following
conditions, replace the torque converter clutch
assembly.
Malfunction item:
A metallic sound is emitted from the
torque converter clutch assembly during
the stall test or when the shift lever is
moved to the N position.
The one-way clutch is free or locked in
both directions.
The amount of powder in the ATF is
greater than the sample shown on the
illustration (see the sample).
HINT:
The sample shows the auto fluid of
approximately 0.25 liters (0.26 US qts, 0.22
Imp. qts) that is taken out from the removed
torque converter clutch.
(c) Exchange the ATF in the torque converter clutch.
(1) If the ATF is discolored and/or has a foul odor,
completely stir the ATF in the torque converter
clutch and drain it with the torque converter
facing up.

(d) Clean and check the oil cooler and oil pipe line.
(1) If the torque converter clutch is inspected or the
ATF is exchanged, clean the oil cooler and oil
pipe line.
HINT:
• Spray compressed air of 196 kPa (2 kgf/cm
2, 28 psi) from the inlet hose.
• If plenty of fine powders are identified in the
ATF, add new ATF using a bucket pump and
clean it again.
(2) If the ATF is cloudy, inspect the oil cooler
(radiator).
(e) Prevent deformation of the torque converter clutch
and damage to the oil pump gear.
(1) When there is any damage on the end of the
bolt for the torque converter clutch and on the
bottom of the bolt hole, replace the bolt and the
torque converter clutch.
(2) All of the bolts must be same length.
(3) Bolts with washers must be used.
2. INSPECT DRIVE PLATE & RING GEAR SUB-
ASSEMBLY
(a) Set up a dial indicator with a roller instrument and
measure the drive plate runout.
(b) Check for damage of the ring gear.
Maximum runout:
0.20 mm (0.0079 in.)
If runout is not within specification or ring gear is
damaged, replace the drive plate.

(b) Place SST on the piston return spring, and
compress the piston return spring with a press.
SST 09387-00060
(c) Using a screwdriver, install the snap ring.
(d) Be sure that the end gap of the snap ring is not
aligned with the spring retainer claw.
NOTICE:
• Stop the press when the spring seat is
lowered to the place 1 to 2 mm (0.039 to 0.078
in.) from the snap ring groove.
• This prevents the spring seat from being
deformed.
