3) Run at "D" range lock-up or OD gear and check for
abnormal noise and vibration.
NOTE:
The check for the cause of abnormal noise and vibration
must be made with extreme care as it could also be due to
loss of balance in the propeller shaft, differential, the
torque converter, etc. or insufficient bending, rigidity, etc.
in the power train.
4) While running in "D" range, 2nd, 3rd gears and OD, check
to see that the possible kick-down vehicle speed limits for 2
1, 3 1, 3 2, OD 3 and OD 2 kick-downs
conform to those indicated on the automatic shift diagram.
5) Check for abnormal shock and slip at kick-down.
6) While running in "D" range, OD gear or "lock-up", shift to
"2" and "L" ranges and check the engine braking effect at
each of these ranges.
7) Also check to see that downshift is made from 3
2 or
from OD to 3 and then to 2 immediately and that 2
1
downshift point is within the limits shown in the diagram
when tested by releasing the accelerator pedal and shifting
into position of "L" while driving in the third gear or in
overdrive.
EVALUATION
(1) If there is no engine braking effect in the "2" range:
• Second coast (No. 1) brake is defective.
(2) If there is no engine braking effect in the "L" range:
• First and reverse (No. 3) brake is defective
(3) Also check to see that downshift is made from 3
2 or
from OD to 3 and then to 2 immediately and that 2
1
downshift point is within the limits shown in the diagram
when tested by releasing the accelerator pedal and shifting
into "L" position while driving in the third gear or in
overdrive.

"2" RANGE TEST
Shift into "2" range and, while driving with the accelerator pedal
held constantly at the specified point (throttle valve opening
50% and 100%), push in one of the pattern selectors (only for
4x4) and check on the following points.
1) At each of the above throttle openings, check to see that
the 1
2 up-shift takes place and that the shift points
conform to those shown on the automatic shift diagram.
NOTE:
There is no OD and no lock-up in the "2" range.
2) While running in the "2" range and 2nd gear, release the
accelerator pedal and check the engine's braking effect.
3) Check for 2
1 down-shift and abnormal noise at
acceleration and deceleration, and for shock at upshift and
down-shift.
"L" RANGE TEST
1) While running above 90 km/h (56 mph) in the "D" range,
release your foot from the accelerator pedal and shift into
the "L" range.
Then check to see that the 2
1 and 3 2 down-shift
occurs at the specified point shown on the automatic shift
diagram.
2) While running in the "L" range, check to see that there is no
up-shift to 2nd gear.
3) While running in the "L" range, release the accelerator
pedal and check the engine braking effect.
4) Check for abnormal noise during acceleration and
deceleration.
"R" RANGE TEST
Shift into the "R" range and, while starting at full throttle, check
for slipping.
"P" RANGE TEST
Stop the vehicle on a grade (more than 9%) and after shifting
into the "P" range, release the parking brake. Then check to
see that the parking lock pawl holds the vehicle in place.

TRANSIMISSION FLUID LEVEL AND
CONDITION
Park vehicle on level ground and set parking brake.
With the engine idling, move the shift lever through all
positions from "P" to "L", then return to position "P".
Check to see If the level of fluid comes to "HOT" range
of about 80
C (176F) on the dipstick gauge.
If the level of fluid is too low, replenish to bring it to
maximum level in "HOT" range.
Inspection of fluid condition
If the ATF is black or smells burnt, replace it.
ATF REPLACEMENT
NOTE:
Do not overfill.
1) Remove the drain plug from oil pan and drain the
fluid.
2) Reinstall the drain plug securely.
3) With the engine OFF, add new fluid through the filler
tube.
4) Star t the engine and shift the selector into all
position from "P" through "L", and then shift into "P".
5) With the engine idling, check the fluid level. Add fluid
up to the "COLD" level on the dipstick.
6) The ATF level must be checked again for correct
level with the "HOT" level.
NOTE:
To prevent fluid leaks, the drain plug gasket must be
replaced each time this plug is removed.

BRAKE SIGNAL INSPECTION
Check that the brake light comes on when the brake pedal is
depressed.
VEHICLE SPEED SENSOR INSPECTION
1. Connect the Vehicle speed sensor connector terminal (1) to
the battery ( +) terminal and terminal (2) to the battery (-)
terminal.
2. Connect a resistance of 1.3k ohm to 5k ohm (1.4W or
more) between terminals (1) and (3).
NOTE:
Be extremely careful not to connect the battery (+) terminal
to the terminal (3)
This may damage the vehicle speed sensor.
3. Rotate the shaft of the vehicle speed sensor slowly and
measure the voltage at both ends with a digital tester.
Replace the sensor when the result of inspection is found
abnormal.
INPUT AND OUTPUT REVOLUTION
SENSOR INSPECTION
Use an ohmmeter to measure the resistance between
terminals 1 and 2.The voltage, with one rotation of shaft, fluctuates four
times in the following range: 10 to 14V
2V or less.
Standard resistance 560 – 680
(20C)
610 – 740
(40C)

3) Make sure of proper operation of shift lock through checks
as follows:
a. Selector lever shall not be moved out of "P" position with
ingition key in "Lock" position.
b. Selector lever can be moved out of "P" position with
ignition key in "ON" position only when brake pedal is
depressed.
c. Ignition key can be turned to "LOCK" position only when
selector lever is in "P" position (key can be pulled out).
If (a) and (c) fail, readjust cable. If (b) fails, readjust
connector wiring and brake pedal switch.
