OPERATION OF CLUTCH, BRAKE AND ONE-WAY CLUTCH
:Operating :Free at coast down :Operating at Lock-up
(1*): Down-shift only in the L range and 2nd
gear - no up-shift.
(2*): Down-shift only in the L range and 3rd gear - no up-shift.
SPEED CHANGE AND LOCK-UP PATTERN
If you select a speed range and a lock-up pattern as shown below by specifying respective positions of transmission
shift lever, transfer shift lever and pattern select switch, the transmission control computer controls speed change and
lock-up operations based on the specified pattern in accordance with the degree of throttle opening and vehicle speed.

: The lock-up operation is available.
( ): Transmission is shifted at high speed to prevent overrun.

STALL TEST
The object of this test is to check the overall performance of the
transmission and engine by measuring the maximum engine
speeds at the "D" and "R" ranges.
NOTE:
(1) Perform the test at normal operation fluid temperature
(50 – 80
C or 122 – 176F).
(2) Do not continuously run this test longer than 5
seconds.
MEASURE STALL SPEED
1) Chock the four wheels.
2) Mount an engine tachometer.
3) Fully apply the parking brake.
4) Step down strongly on the brake pedal with your left foot.
5) Star t the engine.
6) Shift into the "D" range. Step all the way down on the
accelerator pedal with your right foot. Quickly read the
highest engine rpm.
7) Perform the same test in the "R" range.
EVALUATION
1) If the engine speed is the same for both ranges but lower
than the specified value:
• Engine output is insufficient.
• Stator one-way clutch is not operating properly.
NOTE:
If more than 600 rpm below the specified value, the torque
converter could be faulty.
2) If the stall speed in only "D" range is higher than specified:
• Line pressure too low
• Forward clutch slipping
• No. 2 one-way clutch not operating properly
3) If the stall speed in only "R" range is higher than specified:
• Line pressure too low
• Direct clutch slipping
• No. 3 brake slipping
4) If the stall speed in the "R" and "D" ranges are higher than
specified:
• Line pressure too low
• Improper fluid levelStall speed 2450
150rpm

TIME LAG TEST
If the shift lever is shifted while the engine is idling, there will be
a cer tain time elapse or lag before the shock can be felt. This is
used for checking the condition of the forward clutch, direct
clutch, No. 3 brake, and No. 2 one-way clutch.
NOTE:
(1) Perform the test at normal operation fluid temperature
(50 – 80
C or 122 – 176F).
(2) Be sure to allow one minute interval between tests.
(3) Make three measurements and take the average value.
MEASURE TIME LAG
1) Fully apply the parking brake.
2) Start the engine.
Check idling speed (A/C OFF)
3) Shift the shift lever from "N" to "D" range. Using a stop
watch, measure the time it takes from shifting the lever until
the shock is felt.
4) In same manner, measure the time lag for "N"
"R".
EVALUATION
1) If "N" "D" time lag is longer than specified:
• Line pressure too low
• Forward clutch malfunction
• No. 2 one-way clutch not operating properly
2) If "N"
"R" time lag is longer than specified:
• Line pressure too low
• Direct clutch malfunction
• No. 3 brake malfunction
3) If both time lag is longer than specified:
• Line pressure too low"N" range 695 – 745 rpm
Time lag Less than 0.7 seconds
Time lag Less than 1.2 seconds

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.
