TORQUE CONVERTER CLUTCH
INSTALLATION
1. INSTALL TORQUE CONVERTER CLUTCH IN
TRANSMISSION
2. CHECK TORQUE CONVERTER CLUTCH INSTALLATION
Using calipers and a straight edge, measure between the
installed surface of the transmission and the straight edge.
Clearance:
Less than 0.1 mm (0.004 in.)
TORQUE CONVERTER CLUTCH AND
DRIVE PLATE INSPECTION
1. INSPECT ONE±WAY CLUTCH
(a) Install SST into the inner race of the one±way clutch.
SST 09350±30020 (09351±32010)
(b) Install SST so that is fits in the notch of the converter clutch
hub and outer race of the one±way clutch.
SST 09350±30020 (09351±32020)
(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 clutch and retest the clutch.
Replace the converter clutch if the clutch still fails the test. AT2±26

2. MEASURE DRIVE PLATE RUNOUT AND INSPECT RING
GEAR
Set up a dial indicator and measure the drive plate runout.
Maximum runout:
0.20 mm (0.0079 in.)
If runout exceeds 0.20 mm (0.0079 in.) or if the ring gear is
damaged replace the drive plate. If installing a new drive
plate, note the orientation of spacers and tighten the bolts.
Torque: 64 NVm (650 kgfVcm, 47 ftVlbf)
3. MEASURE TORQUE CONVERTER CLUTCH SLEEVE
RUNOUT
(a) Temporarily mount the torque converter clutch to the drive
plate. Set up a dial indicator.
Maximum runout:
0.30 mm (0.0118 in.)
If runout exceeds 0.30 mm (0.0118 in.), try to correct by reori-
enting the installation of the converter clutch.
If excessive runout cannot be corrected, replace the torque
converter clutch.
HINT: Mark the position of the converter clutch to ensure cor-
rect installation.
(b) Remove the torque converter clutch.

PROBLEM SYMPTOM CONFIRMATION
Taking into consideration the results of the customer problem analysis, try to reproduce the symptoms of
the trouble. If the problem is that the transmission does not up±shift, does not down±shift, or the shift point
is too high or too low, conduct the following road test to confirm the automatic shift schedule and simulate
the problem symptoms.
ROAD TEST
NOTICE: Do the test at normal A/T fluid operating temp.
50±805C (122±1765F).
1. D POSITION TEST (NORM PATTERN)
Shift into the D position and keep the accelerator pedal
constant at the full throttle valve opening position, and check
the following points:
(a) Check up±shift operation.
Check that 1±2, 2±3 and 3±O/D up±shift takes place, at the
shift point shown in the automatic shift schedule.
(See page AT2±116)
HINT:
(1) O/D Gear Up±shift Prohibition Control.
wCoolant temp. is 605C (1405F) or less.
wIf there is a 10 km/h (6 mph) difference between the set
cruise control speed and vehicle speed.
wO/D main switch is pushed ON.
`(During O/D OFF, indicator light lights up.)
(2) O/D Gear Lock±up Prohibition Control.
wBrake pedal is depressed.
wCoolant temp. is 605C (1405F) or less.
(b) Check for shift shock and slip.
Check for shock and slip at the 1±2, 2±3, and 3±O/ D up±
shifts.
(c) Check for abnormal noise and vibration.
Run at the D position lock±up or O/D gear and check for ab-
normal noise and vibration.
HINT: The check for the cause of abnormal noise and vibra-
tion must be performed very thoroughly as it could also be
due to loss of balance in the, torque converter clutch, etc.
± A340E (2JZÐGTE) AUTOMATIC TRANSMISSIONTROUBLESHOOTINGAT2±37

(c) Check for abnormal noise and vibration.
Run at the D position lock±up or O/D gear and check for ab-
normal noise and vibration.
HINT: The check for the cause of abnormal noise and vibra-
tion must be made with extreme care as it could also be due
to loss of balance in the propeller shaft, differential, torque
converter clutch, etc.
(d) Check kick±down operation.
While running in the D position, 2nd, 3rd and O/D gears,
check to see that the possible kick±down vehicle speed limits
for 3
" 2 and O/D " 3 kick±downs conform to those indicated
on the automatic shift schedule.
(See page AT2±116)
(e) Check for abnormal shock slip at kick±down.
(f) Check the lock±up mechanism.
(1) Drive in D position, O/D gear, at a steady speed (lock±up
ON) of about 195 km/h (121 mph).
(2) Lightly depress the accelerator pedal and check that the
engine RPM does not change abruptly.
If there is big jump in the engine RPM there is no lock ±up.
3. 2 POSITION TEST (NORM PATTERN)
Shift into the 2 position and, while driving with the accelerator
pedal held constantly at the full throttle valve opening posi-
tion, check on the following points:
(a) Check up±shift operation.
Check to see that the 1
" 2 up±shift takes place and that the
shift point conforms to the automatic shift schedule.
(See page AT2±116)
HINT: There is no O/D up±shift and lock±up in the 2 position.
(b) Check engine braking.
While running in the 2 position and 2nd gear, release the ac-
celerator pedal and check the engine braking effect.
