REMOVAL
1) Pull out dipstick and lift up vehicle.
2) With engine cooled, remove drain plug from oil pan and drain
A / T fluid.
3) Install drain plug with gasket.

4) Remove exhaust pipe bracket and disconnect front propeller
shaft from front differential (if equipped).
5) Remove oil pan bolts.
6) Remove oil pan.
7) Remove oil tubes.
8) Remove solenoid valve No.1 (shift solenoid valve A and B) or so-
lenoid valve No.2 (TCC solenoid valve).
OPERATION CHECK
Whenever shift solenoid valves and TCC (lock-up) solenoid valve
are removed from transmission, verify their valve function physical-
ly before they are reinstalled.
1) Apply oiler to solenoid valve and give compression by hands
and then check to be sure that transmission fluid from oiler does
not come out of holes in solenoid valve when battery voltage is
not conducted.
2) Under the same conditions as above, conduct battery voltage
and then make sure that fluid comes out with vigor.
NOTE:

If fluid does not come out with vigor in above step 2 in-
spection, do not re-use that solenoid valve.

Figure at the left shows shift solenoid valve check.
Check TCC solenoid valve also in the same way.

INSTALLATION
Reverse removal procedure to install solenoid valves and noting
the following points.

For details of solenoid valve installation, refer to ªUnit Repairº
section. Use new gasket and O-ring.

Install oil tubes in such order as shown in figure.

For details of oil pan installation, refer to ªUnit Repairº section.
Use new oil pan gasket.

Tighten universal joint flange bolts & nuts and exhaust pipe brack-
et bolts to specified torque.

Fill A / T fluid and check fluid level according to procedure de-
scribed in ªCHANGING FLUIDº previously.

Check for fluid leakage after warming up A / T.

OIL COOLER PIPES
REMOVAL
1) Lift up vehicle.
2) Make sure to wash dirt off from around pipe joints.
3) With engine is cool, loosen oil cooler pipe union bolts with oil out-
let union locked and remove oil cooler pipes from oil outlet
unions and hoses.
NOTE:
To avoid fluid leakage, plug open ends of oil outlet unions
and hoses right after they are disconnected.
INSTALLATION
1) Use new union gaskets and connect oil cooler pipes to oil outlet
unions.
2) Connect hoses to pipes and clamp them securely.
3) Tighten union bolts to specified torque with oil outlet union
locked.
Tightening Torque

4) Tighten pipe bolt securely.
5) Check A / T fluid level according to procedure described in ªFluid
Levelº section.
Add if necessary.
6) Check for fluid leakage after warming up A / T.

1) Drain transfer oil for 4WD vehicle or A / T fluid for 2WD vehicle.
NOTE:
If 4WD automatic transmission is overhauled later on,
draining A / T fluid at this point will facilitate work.

2) Before removing propeller shaft, give match marks on joint
flange and propeller shaft as shown in left figure.
3) Remove universal joint flange bolts and take out rear propeller
shaft.
4) Likewise, take out front propeller shaft. (if equipped)
5) Remove nut from the end of select cable and bracket to set
cable free.
6) Remove select cable bracket by removing its 2 bolts.
7) Remove exhaust No.1 and No.2 pipe.
8) Remove transmission stiffener (right side) if equipped.
9) Unclamp and disconnect oil cooler hoses from pipes.
NOTE:
To avoid leakage of transmission fluid, plug open ends of
oil cooler pipes and hoses right after they are discon-
nected.
10) Remove torque converter housing lower plate.
11) Holding drive plate stationary with special tool or the like, re-
move torque converter mounting bolts with wrench.

12) Remove engine to transmission nuts.
13) Disconnect connectors from VSS, output speed sensor, input
speed sensor, TR switch, shift & TCC solenoid valves and oth-
er electrical parts, and release their wire harness from clamps.
14) Apply transmission jack and take off rear mounting member by
removing its bolts.
15) With transmission (and transfer if equipped) assembly held up
on jack, move them to the rear and lower them including torque
converter.
WARNING:
Transmission (and transfer if equipped) assembly may
tilt rearward on jack. It is recommended to use an auxil-
iary arm of jack for the purpose of safety.
AFTER DISMOUNTING
WARNING:
Be sure to keep transmission (and transfer if equipped) as-
sembly horizontal throughout the work. Should they be
tilted, torque converter may fall off and cause personal inju-
ry and A / T fluid may flow out.
1) Remove breather hoses.
2) Remove transfer by removing its bolts, if equipped.
