(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 indi-
cated on the automatic shift schedule.
(See page AT1±96)
(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 172 km/h (107 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 AT1±96)
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.

Front Passenger Airbag:
Visually inspect the front passenger airbag assembly (airbag
and inflater).
wUse the diagnosis check to check if there are
abnormalities.
wCheck that there are no cuts, cracks or noticeable color
changes in the front passenger airbag door.
wRemove the front passenger airbag assembly from the
vehicle and check the wiring and front passenger airbag
door for damage and corrosion due to rusting, etc.
If necessary, replace the front passenger airbag assembly.
CAUTION:
wFor removal and replacement of the steering wheel pad
or front passenger airbag assembly, see RS section and
be sure to perform the operation in the correct order.
wBefore disposing of the steering wheel pad or front pas-
senger airbag assembly must first be deployed by using
SST (See RS section).
18. INSPECT STEERING GEAR HOUSING OIL
Check the steering gear housing for oil leakage.
19. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
wJack up the front of the vehicle and support it with
stands.
wMake sure the front wheels are in a straight±ahead
position, and depress the brake pedal.
wJack up the lower suspension arm until there is about
half a load on the front coil spring.
wMove the front wheel up and down and check that the
ball joint has no excessive play.
Maximum lower ball joint vertical play:
0.3 mm (0.012 in.)
If the play is greater than maximum, replace the ball joint.
(b) Visually check the dust covers for damage.
20. I NSPECT TRANSMISSION OIL (FLUID) AND
DIFFERNTIAL OIL
Visually check the transmission and differential for oil (fluid)
leakage.
If leakage is found, check for the cause and repair.

21. REPLACE TRANSMISSION OIL (FLUID) AND
DIFFERENTIAL OIL
A. Replace manual transmission oil
(a) Remove the filler and drain plugs, and drain the oil.
(b) Reinstall the drain plug securely.
(c) Add fresh oil untill it begins to run out of the filler hole.

B. Replace automatic transmission fluid
(a) Remove the drain plug, and drain the fluid.
(b) Clean the drain plug.
(c) Reinstall the drain plug securely.
