AND DRIVE PLATE
INSPECTION
1. INSPECT ONE±WAY CLUTCH
(a) Install SST into the inner race of the one±way clutch.
SST 09350±32014 (09351±32020)
(b) 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)
(c) With the torque converter clutch standing on its side,the
clutch locks when turned counterclockwise, and rotates
freely and smoothly clockwise.
If necessary, clean the converter and retest the clutch.
Replace the converter if the clutch still fails the test.
2. MEASURE DRIVE PLATE RUNOUT AND INSPECT
RING GEAR
(a) Set up a dial indicator, and measure the drive plate run-
out.
(b) Check the damage of the ring gear.
Maximum runout: 0.20 mm (0.0079 in.)
If the runout is not within specification or ring gear is damaged,
replace the drive plate.
Torque: 83 N´m (850 kgf´cm, 61 ft´lbf)

3. MEASURE TORQUE CONVERTER CLUTCH SLEEVE
RUNOUT
(a) Temporarily mount the torque converter clutch to the drive
plate. Set up a dial indicator and measure the torque con-
verter clutch sleeve runout.
Maximum runout: 0.30 mm (0.0118 in.)
If the runout is not within the specification, try to correct by reori-
enting the installation of the converter.
HINT:
Mark the position of the converter to ensure the correct installa-
tion.
(b) Remove the torque converter clutch.

1. FUNCTION OF COMPONENTS
FUNCTIONOPERATION
O/D Direct Clutch (C0)Connects overdrive sun gear and overdrive carrier
O/D Brake (B0)Prevents overdrive sun gear from turning either clockwise or
counterclockwise
O/D One±way Clutch (F0)When transmission is being driven by engine, connects overdrive sun
gear and overdrive carrier.
Front Clutch (C1)Connects input shaft and intermediate shaft
Rear Clutch (C2)Connects input shaft and front and rear planetary sun gears
No.1 Brake (B1)Prevents front and rear planetary sun gears from turning either clockwise
or counterclockwise
No.2 Brake (B2)Prevents outer race of F1 from turning either clockwise or counterclockwise, thus
previnting front and rear planetary sun gears from turning counterclockwise
No.3 Brake (B3)Prevents front planetary carrier from turning either clockwise or counterclockwise
No.1 One±way Clutch (F1)When B2 is operating prevents front and rear planetary sun gears from turning
counterclockwise
No.2 One±way Clutch (F2)Prevents front planetary carrier from turning counterclockwise

AUTOMATIC TRANSAXLEOPERATION ±
AX±5
Power from the engine transmitted to the input shaft via the torque converter is then transmitted to the
planetary gears by the operation of the clutch.
By operation of the brake and one±way clutch, either the planetary carrier or the planetary sun gear
are immobilized, altering the speed of revolution of the planetary gear unit.
Shift change is carried out by altering the combination of clutch and brake operation.
Each clutch and brake operates by hydraulic pressure; gear position is decided according to the throttle
opening angle and vehicle speed, and shift change automatically occurs.
The conditions of operation for each gear position are shown on the following illustrations:
