AUTOMATIC TRANSMISSION AND DIFFERENTIAL
If any of these phenomena are noted,
it is attributable to excessively small
brake band clearance: Loosen the
adjust screw by turning it counter-
clockwise.
3) When accelerating, direct shift up
from 1 st to 3rd occurs:
........ Excessively large clearance.
When shifting up from 2nd to 3rd, tire
slip occurs:
. : ...... Excessively small clearance.

screw
2) Adjustment of the adjusting screw
1) Using a socket wrench, immobi-
lize the end of the 10 mm screw
projecting on the left side of the trans-
mission case, and loosen the nut with
a double-end wrench.
In the case of occurrence of problems
1) and 2) mentioned previously, per-
form the adjustment by loosening or
tightening the nut within a range of
3/4 turn from this state.
NOTE:
Tool No.

Socket wrench
00 not loosen excessively; otherwise,
the band strut on the servo piston will
drop off.
2) In case of the occurrence of prob-
lem 3) mentioned previously, perform
the adjustment as follows:
Adjusting procedure: Tighten adjust
screw to 9 N·m (0.9 kg-m, 6.5 ft-Ib)
torque, then back off two turns.
NOTE:
Do not tighten the adjusting screw
with an excessively large torque.
3) With the adjusting screw immobi-
lized, tighten the lock nut to 26±2 N·m
(2.7±0.2 kg-m, 20±1.4 ft-Ib) torque.
11) Inspection, Removal and
Installation of the Transfer
Solenoid (4WD Models)
If the 4WD pilot lamp on the instru-
ment panel remains off even when the
4WD pushbutton switch has been de-
pressed, check the transfer solenoid
and wiring.
If the 4WD mode is not achieved with
the lamp illuminated, the solenoid
may be malfunctioning. Check the
solenoid and transfer valve as follows.
• Removal and installation of
solenoid (transfer valve)
• Removal
1) Open the hood.
2) Disconnect the battery ground
cable.
3) Remove the spair tire.
4) Loosen the pitching stopper (to a
position just before it comes oft).
5) Disconnect the 4WD selector sole-
noid harness. (Keep the disconnected
harness suspended.)

solenoid harness
6) Remove the uppercover. [This is
necessary for removing the exhaust
pipe (F).]
7) Remove the exhaust pipe (F).
8) Remove the intermediate side
cable clamp. .
9) Drain the torque converter oil
(one liter).
(The oil will not come out of the case
when the valve is removed, if one liter
of oil has been drained. Measure the
drained amount so that the amount to
be added after completing the inspec-
tion can be easily determined.)

10) Remove the rear crossmember.
(To ensure safety, support the oil pan
with a transmission jack.)
11) Remove the side cable from the
body clip. (Move it downward as far
as possible.)
12) Push the transmission to the left.
(Insert a piece of wood between the
clearance thus achieved.)
13) Remove the solenoid valve.

• Installation
Reverse the sequence of removal pro-
cedure.
12) Disassembly, Inspection
and Assembly of the
Transfer Section
(4WD Model)
I) Disassembly
1) Completely drain the AFT.
2) Remove the transfer solenoid.
Refer to the Removal and Installation
of the Transfer Solenoid for details.
3) Remove the temperature switch
harness from the clamp.
4) Remove the eight 8 mm bolts and
extract the transfer section and exten-
sion ASSY as a unit from the inter-
mediate case.
NOTE:
a. Be careful not to drop the internal
component parts.
b. Place a container to collect the
remaining oil.
