FLUSHING THE TRANSMISSION FLUID COOLER AND LINE
The fluid cooler and lines may be flushed under the
following condition. This will help prevent more trouble
after the transmission is repaired.
1. W hen an abnormal amount of debris is found.
2. W hen an abnormal wear or chips on gears and shafts is found while overhauling.
3. W hen there is abnormal clutch facing wear and oil contamination found.

Procedures
1. Block the wheels.
2. Disconnect the negative battery cable.
3. Raise the vehicle and support it with suitable safet
y
stands.
4. Disconnect the fluid cooler lines at the transmission case and fluid cooler.
5. Flush and back-flush the fluid cooler and lines using solvent and compressed air.
Note:
DO NOT exceed (200 kPa/2.0 kgf/cm
2/28 psi) air
pressure, or damage may result to oil cooler.

6. Remove all remaining solvent from the system with
compressed air.
7. Flush the cooling system again with Automatic Transmission Fluid (ATF).
After the final flush, connect all lines.
Cooler line joint connector torque :
44 N·m (4.5 kgf·m/33 lb·ft)
8. Replenish the ATF.
9. Start the engine to test the system for the free flow o
f
fluid. If the flow is restricted, the cooler assembly o
r
lines must be replaced.
Repeated cleaning and flushing may not remove all the debris from the fluid cooler circuit.
Move the select lever through the various ranges and return to neutral.
Check for fluid level.
If the fluid level is below the specified range, ATF must be added.
10. Connect the negative battery cable.
11. Remove the safety stands.

AUTOMATIC TRANSMISSION
REASSEMBLY
Assembly cautions
• Use your bare hands or vinyl gloves to reassemble the
transmission. Do not use ordinary work gloves (loosen
threads from the gloves may fall into the transmission
and cause problems).
• Before installing the drive plates, immerse them in the
recommended automatic transmission fluid (BESCO
ATF III). If the drive plate is new, it must be immersed
for at least two hours to ensure oil penetration and
saturation of the facing.
•
Apply ATF to all sliding and contact surfaces before
assembly. Also apply ATF to seal rings and O-rings.
Assemble the parts carefully to avoid damaging them.
• Replace any snap ring that appears worn, bent out o
f
shape, or damaged.
• If any part contacting the transmission case is damaged,
it must be replaced with a new part.
• Be careful not to damage the plates during reassembl
y
(oil leakage from the plate will result).
• If you are reusing a seal, remove the old adhesive agent
and clean the surface with cleaning oil before applying
the new adhesive agent.
• W ait at least two hours after installing the oil seals
before installing the plates.
• Do not replace O-rings, snap rings, bearings, and/o
r
bearing races with inferior substitutes.

7D-12 TRANSFER CASE
Removal
NOTE: Before removing transmission and transfer
assembly from vehicle, change the transfer mode to
2W D using the 4W D push button switch on dash panel.
1. Disconnect battery ground cable.
2. Raise and support vehicle with suitable stands. Drain
transfer case fluid.
3. Remove rear propeller shaft and front propeller shaft.
NOTE: Apply alignment marks on the flange at both front
and rear sides.
4. Disconnect harness connectors and clip.
Connector: transfer switch, 2W D-4W D actuator,
speed sensor.
NOTE: Avoid turning the vehicle ignition switch to the ON
position when the 2W D-4W D connector is removed
(battery connected).
If the ignition switch must be turned to the ON position,
the controller must first be removed (memory must be
cleared because the CHECK 4W D INDICATOR will
light).
5. Remove transfer case assembly from the vehicle.
Installation

1. Apply a thin coat of molybdenum disulfide grease to
the input shaft spline as shown in the figure.
