HYDRAULIC TEST
PREPARATION
1) Warm up the transmission fluid.
2) Remove the transmission case test plug and mount the
hydraulic pressure gauge.
Oil pressure gauge: 5-8840-0093-0
NOTE:
Perform the test at normal operating fluid temperature (50
– 80
C or 122 – 176F).
MEASURE LINE PRESSURE
1) Fully apply the parking brake and chock the four wheels.
2) Start the engine and check idling rpm.
3) Shift into "D" range, step down strongly on the brake pedal
with your left foot and, while manipulating the accelerator
pedal with the right foot, measure the line pressures at the
engine speeds specified in the table.
4) In the same manner, perform the test in "R" range.
EVALUATION
1) If the measured values at all ranges are higher than
specified.
• Pressure control solenoid defective.
• Primary regulator valve defective.
2) If the measured values at all ranges are lower than
specified.
• Primary regulator valve defective.
• Oil pump defective.
• Pressure control solenoid defective.
3) If pressure is low in "D" range only:
• "D" range circuit fluid leakage.
4) If pressure is low in "R" range only:
• "R" range circuit fluid leakage. Engine

"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.
