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.

Do not stake the transfer gear nut.
HINT:
Use a torque wrench with a fulcrum length of 750
mm (29.53 in.)
8. INSPECT AND ADJUST DRIVEN PINION PRELOAD
(a) Using SST(s) and a torque wrench, measure thee
initial torque of the driven pinion.

bearing spacer with a new one.
(c) If the preload is too small, repeatedly adjust the
preload by tightening the transfer gear nut 5 to 10
degrees at a time until the standard value is
obtained.
