TORQUE CONVERTER CLUTCH
AND DRIVE PLATE
INSPECTION
1. INSPECT ONE-WAY CLUTCH
(a) Install SST in the inner race of the one-way clutch.
SST 09350-32014 (09351-32010)
(b) Install SST so that it fits in the notch of the converter clutch
hub and outer race of the one-way clutch.
SST 09350-32014 (09351-32020)
(c) With the torque converter clutch held upright, inspect the
clutch locks when turned counterclockwise, and rotates
freely and smoothly clockwise.
If necessary, clean the converter and retest the clutch. Replace
the converter clutch if the clutch still fails the test.
2. MEASURE DRIVE PLATE RUNOUT AND INSPECT
RING GEAR
Set up a dial indicator, measure the drive plate runout.
Maximum runout: 0.20 mm (0.0079 in.)
If the runout is not within the specification, replace the drive
plate. If installing a new drive plate, note the orientation of
spacers and tighten the bolts.
Torque: 88 N´m (900 kgf´cm, 65 ft´lbf)
3. MEASURE TORQUE CONVERTER CLUTCH SLEEVE
RUNOUT
Temporarily mount the torque converter clutch to the drive
plate. Set up a dial indicator, measure the torque converter
clutch sleeve runout.
Maximum runout: 0.30 mm (0.0018 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 clutch to ensure the correct
installation.

EVALUATION
ProblemPossible cause
If there is no 1 - 2 up-shift.
Governor valve is defective

1 - 2 shift valve is stuck
If there is no 2 - 3 up-shift.
1 - 2 shift valve is stuck
If there is no 3 - O/D up-shift
(throttle valve operating less than 86%).
3 - O/D shift valve is stuck

Solenoid valve or circuit defective
If the shift point is defective.

Throttle cable out of adjustment

Throttle valve, 1 - 2 shift valve, 2 - 3 shift valve, 3 - O/D shift valve etc. are
defective
(2) In the same way, check the shock and slip at 1 " 2, 2 " 3 and 3 "O/D up-shifts.
EVALUATION
ProblemPossible cause
If the shock is severe.

Line pressure is too high

Accumulator is defective

Check ball is defective
(3) Run in the 3rd gear or O/D of the D position, check the abnormal noise and vibration.
HINT:
Check for the cause of abnormal noise and vibration must be made with extreme care as they could also
be due to unbalance in the drive shaft, differential, tires and torque converter clutch, etc.
(4) While running in the 3rd gear or O/D of the D position, check that the possible kick-down vehicle
speed limits for the 3 " 1, 3 " 2 and O/D "2 kick-down conform to those indicated in the auto-
matic shift schedule (See page SS-30).
EVALUATION
ProblemPossible cause
If the possible kick-down vehicle speed limit is defective.

Throttle cable out of adjustment

Throttle valve, 1 - 2 shift valve, 2 - 3 shift valve, 3 - O/D shift valve etc. are
defective
(5) Check the abnormal shock and slip at kick-down.
(6) While running at about 60 km/h (37 mph) in the O/D of the D position, release your foot from the
accelerator pedal and shift into the L position. Then check if the 2 "1 down-shift point conforms
to that indicated in the automatic shift schedule (See page SS-30).
(b) Inspect the lock-up mechanism.
(1) Drive in the D position at a steady speed (Lock-up ON) of about 70 km/h (43 mph).
(2) Lightly depress the accelerator pedal and check that the engine speed does not change abruptly.
If there is a big jump in engine RPM, there is no lock-up.
(c) 2 position test.
(1) While running in the 2nd gear of the 2 position, release the accelerator pedal and check the en-
gine braking effect.
EVALUATION
ProblemPossible cause
If these is no engine braking effect.
2nd coast brake is defective.
(2) Check the abnormal noise during acceleration and deceleration.
(3) Check the shock during up-shift and down-shift.
(d) L position test.
(1) While running in the L position, check that there is no up-shift to 2nd gear.
(2) While running in the L position, release the accelerator pedal and check the engine braking ef-
fect.

EVALUATION
ProblemPossible cause
If these is no engine braking effect.
1st & reverse brake is defective.
(3) Check for abnormal noise during acceleration and deceleration.
(e) R position test.
Shift into the R position and, while running at full throttle, check for slipping.
(f) P position test.
Stop the vehicle on a gradient (more than 5°) and, after shifting into the P position, release the parking
brake. Then check that the parking lock pawl prevents the vehicle from moving.

2. INSPECT KEY INTERLOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minals.
Standard resistance: 12.5 - 16.5 W
If the resistance is not as specified, replace the solenoid.
(c) Apply battery positive voltage between terminals. Check
that the solenoid operation sound is heard.
If the operation is not as specified, replace the solenoid.
