7. BASIC INSPECTION
(a) Check the ATF level.
HINT:
The vehicle must have been driven so that the engine and
transaxle are at normal operating temperature.
ATF temperature: 70 − 80°C (158 − 176°F)
(1) Park the vehicle on a level surface, set the parking
brake.
(2) With the engine idling and the brake pedal de-
pressed, shift the shift lever into each gear from the
P position to L position smoothly and return to the
P position.
(3) Pull out the transaxle dipstick and wipe it clean.
(4) Push it back fully into the pipe.
(5) Pull it out and check that the fluid level is in the HOT
range.
If the level is at the low side of the hot range, add fluid.
Fluid type: ATF type T or equivalent
NOTICE:
Do not overfill.
(b) Check the transfer oil level.
(1) Park the vehicle on a level surface, set the parking
brake.
(2) Pull out the transfer dipstick and wipe it clean.
(3) Push it back fully into the pipe.
(4) Pull it out and check the oil level, as shown in the il-
lustration.
Oil grade: API GL−5
Oil viscosity: SAE 75W−90

(d) Replace the ATF.
NOTICE:
Do not overfill.
(1) Using a 10 mm hexagon wrench, remove the drain
plug, gasket and drain the fluid.
(2) Install a new gasket and the drain plug securely.
(3) Add new fluid through the filler pipe.
Fluid type: ATF type T or equivalent
Drain and refill: 3.3 liters (3.5 US qts, 2.9 lmp. qts)
(4) Start the engine and shift the selector into all the
positions from P through L and then shift into the P
position.
(5) With the engine idling, check the fluid level. Add
fluid up to the COOL level on the dipstick.
(6) Check the fluid level with the normal fluid tempera-
ture 70 − 80°C (158 − 176°F) and add as neces-
sary.
NOTICE:
Do not overfill.
(e) Replace the transfer oil.
(1) Using a 10 mm hexagon wrench, remove the drain
plug and drain the oil.
(2) Install the drain plug.
(3) Add new oil through the filler pipe.
Recommended oil:
Oil grade API GL−5
Viscosity SAE 75W−90
Capacity: 0.7 liters (0.7 US qts, 0.6 lmp. qts)
(4) Check the oil level and add as necessary.
NOTICE:
Do not overfill.

(f) Check the fluid leaks.
Check for leaks in the transmission and transfer.
If there are leaks, it is necessary to repair or replace O − rings,
FIPG’s, oil seals or other parts.
(g) Inspect and adjust the throttle cable.
(1) Check that the throttle valve is fully closed.
(2) Check that the inner cable is not slack.
(3) Loosen the adjustment nuts.
(4) Adjust the outer cable so that the distance between
the end of the boot and stopper on the cable is as
standard.
Standard boot and cable stopper distance:
0 − 1 mm (0 − 0.04 in.)
(5) Tighten the adjusting nuts.
(6) Recheck the adjustments.
(h) Adjust the shift control cable.
(1) Loosen the nut on the lever.
(2) Push the manual lever fully toward the right side of
the vehicle.

10. Center Differential Control Clutch:
HYDRAULIC TEST
(a) Preparation.
(1) Warm up the ATF.
(2) Remove the test plug and connect SST (See page AX−18 for the location to connect SST).
SST SST 09992−00094 (09992−00111)
CAUTION:
Perform the test at normal operating ATF temperature 50 − 80°C (122 − 176°F)
The line pressure test should always be carried out in pairs. One should observe the conditions
of wheels or wheel stoppers outside the vehicle while the other is performing the test.
(b) Measure the center differential clutch control pressure.
(1) Start the vehicle and open the accelerator open 50 % or more and check that the center differen-
tial clutch control pressure is in the range from more than 294 kPa (3.0 kgf/cm
2, 42 psi).
(2) Fully close the accelerator and check that the SST registers 9.8 kPa (0.1 kgf/cm
2, 1.4 psi) or less.
CAUTION:
Confirm safety of the road before checking.
Take care to avoid slip when you start the vehicle on a paved road.
Check the pressure at normal driving ATF temperature 50 − 80°C (122 − 176°F).
Reference:
To measure center differential control pressure to be measured with the solenoid opened by applying voltage
to it, refer to the following:
Prepare a sub−assembly for checking as follows:
Prepare a supply connector (Part No. 90980−10629, or 90980−11143)
Connect a harness of 2 − 3 m (6.6 − 9.8 ft) to terminal 1 of the connector.
Place a bulb of 24W in between the harness.
Connect a harness of 2 − 3 m (6.6 − 9.8 ft) to terminal 3 of the connector.
Connect the inspection’s sub−harness assembly to the solenoid connector of the transfer.
Connect terminal 1 of the sub−harness to the battery’s positive (+) terminal, and terminal 3 of the sub−
harness to the battery’s negative (−) terminal.
Measure the center differential control pressure at idling and when performing the stall test (When 1st
gear).

CIRCUIT DESCRIPTION
The rear speed sensor detects the rear wheel speed based on
revolution of the transfer drive gear.
Its construction is the same as that of the front speed sensor
(See page DI−206).
The center differential clutch is controlled by the ECM based on
the signals from the front speed sensor and rear speed sensor
signals.
