AUTOMATIC TRANSMISSION AND DIFFERENTIAL
j. Replace gaskets, seals, lock washers,
staking nuts, servo apply pipe and
servo release pipe with new ones
whenever they are disassembled.
k. Drain A TF and differential gear oil
into a saucer so that the conditions
of fluid and oil can be inspected.
2 TORQUE CONVERTER
SECTION
As torque converter is welded all
around
it, it
is impossible to disassem-
ble it.
1) Removal
1) Remove oil pan drain plug and
drain the A TF .
NOTE:
Check the volume and state (color,
smell, etc.) of the A TF.
2) Take out the torque converter
ASSY from converter housing taking
care of the following.
a. Prepare the appropriate saucer
under converter housing to receive
the ATF which pours out from the
torque converter ASSY, turbine
shaft and/or oil pump drive shaft.
b. When taking out torque converter,
turbine shaft and oil pump drive
shaft may come out together.
In this case take them out straight
and gradually not to bend them.
2) Inspection
1) Check the one-way clutch func-
tion of stator with the spline of stator
shaft engaged into stator and replace
if defective.
It is normal that when turning stator
shaft counterclockwise, one-way
clutch is engaged, and when clockwise,
the clutch is released.
2) Check for the exterior damage, oil
leakage, bend and depression, and
replace if defective.
3) Completely take off the rust on
the pilot and/or sleeve of converter.
4) If the ATF is soiled or excessively
deteriorated, wash the interior of
torque converter as follows.
a. Take off the remained ATF in
torque converter.
b. Pour 0.5 Q (0.5 US qt, 0.4 Imp qt)
of gasoline. (unleaded gasoline or
kerosene)
c. Blow in the compressed air to wash
the interior and then drain the
gasoline.
d. Pour 0.5
Q
(0.5 US qt, 0.4 Imp qt)
of ATF.
e. Blow in the compressed air and
drain the A TF.
3) Installation
Install torque converter straight onto
shaft while turning it slowly.
3 DISASSEMBLING THE
ENTIRE AUTOMATIC
TRANSMISSION
1) Transfer Section
(4WD Models)
1) Remove the rear engine mount
(rubber cushion) and place the transfer
unit on a work bench with the oil pan
facing down.
Fig. 7-64 Transfer unit
2) Remove the solenoid from the
transfer unit by turning it by hand.
NOTE:
a. Be sure to remove the solenoid
first.
b. Ensure that the harness is detached
from the clamp before separating
the transfer unit from the engine.
c. Remove the "0" ring together with
the harness.

3) Remove the temperature switch
with a wrench.
NOTE:
Ensure that the harness is detached
from .the clamp in advance.

switch
4)
Remove the extension ASSY.
To do this, remove the eight
8
mm
bolts and extract the transfer section
together with the extension ASSY.
NOTE:
a. Place a container to receive A TF
remaining in the extension.
b. Be careful not to drop the rear
drive gear thrust plate and transfer
drive gear ASSY.
c. Remove the washer from the bear-
ing bore on the upper side of the
intermediate case.
d. Do not place the opening of the
extension ASSY down, as this may
cause the rear shaft ASSY to drop.
2) Transmission Case Section
1) Remove the rear extension ASSY.
(4WD)
2) Drain AFT. (AFT should be
drained when the transmission is dis-
mounted from the vehicle.)
3)
Carefully pull the turbine output
shaft and oil pump drive shaft straight
out.
If they are hard to remove by hand,
wrap their splines with a cloth or vinyl
tape and extract them using pliers. Be
careful not to damage the splines.
4) Disconnect the oil cooler pipe
from the transmission case.
5) Remove the lead wire clips.
To do this, remove the nuts which
secure the transmission case to the
final reduction case, and remove the
