FLUID LEVEL
LEVEL CHECK AT NORMAL OPERATING TEMPERATURE
1) Stop vehicle and place it level.
2) Apply parking brake and place chocks against wheels.
3) With selector at P position, start engine.
4) Warm up engine till fluid temperature reaches normal operating
temperature (70 ± 80C / 158 ± 176F). As a guide to check fluid
temperature, warm up engine till engine coolant temperature
meter indicated around 1 unit above ªCº point.
5) Keep engine idling and shift selector slowly to L and back to P
position.
6) With engine idling, pull out dipstick, wipe it off with a clean cloth
and put it back into place.
7) Pull out dipstick again and check fluid level indicated on it. Fluid
level should be between FULL HOT and LOW HOT. If it is below
LOW HOT, add an equivalent of DEXRON-III up to FULL HOT.
Fluid specification
An equivalent of DEXRON-III
NOTE:

DO NOT RACE ENGINE while checking fluid level, even af-
ter the engine start.

DO NOT OVERFILL. Overfilling can causes foaming and
loss of fluid through breather. Then slippage and trans-
mission failure can result.

Bringing the level from LOW HOT to FULL HOT requires
0.3 liters (0.64/0.53 US/lmp.pt).

If vehicle was driven under high load such as pulling a
trailer, fluid level should be checked about half an hour af-
ter it is stopped.

LEVEL CHECK AT ROOM TEMPERATURE
The fluid level check at room temperature performed after repair or
fluid change before test driving is just preparation for level check of
normal operating temperature. The checking procedure itself is the
same as that described previously. If the fluid level is between FULL
COLD and LOW COLD, proceed to test drive. And when the fluid
temperature has reached the normal operating temperature, check
fluid level again and adjust it as necessary.
FLUID CHANGE
1) Lift up vehicle.
2) With engine is cool, remove drain plug from oil pan and drain A / T
fluid.
3) Install drain plug.

ADJUSTMENT
1) Pull inner cable by force of 2 N (0.2 kg, 0.45 lb) or less to be no
slack of inner cable with A / T throttle cable curved as shown in
the figure.
2) Fix stopper to inner cable with clearance ªcº.
Clearance ªcº : 0.8 ± 1.5 mm (0.03 ± 0.06 in.)
3)For G16 / J20 engines
a) Check clearance ªcº. If it is out of specifications, adjust it by
turning cable adjusting nut.
Clearance ªcº : 0.8 ± 1.5 mm (0.03 ± 0.06 in.)
b) Tighten lock nut securely.
For H25 engine
a) Warm up engine and transmission to normal operating tem-
perature.
b) Make sure that accelerator cable is adjusted as specified.
c) With throttle valve closed, check clearance ªcº which should
be within the following specification.
Clearance ªcº : 0.8 ± 1.5 mm (0.03 ± 0.06 in.)
If it is out of specification, adjust it by turning cable adjusting nut.

BRAKE INTERLOCK SYSTEM
SHIFT LOCK SOLENOID CONTROL
This system consists of shift lock solenoid control system and inter-
lock cable control system.
The shift lock solenoid control system is so designed that the selec-
tor lever can not be shifted from ªPº range position unless the igni-
tion switch is turned ON and the brake pedal is depressed. And the
interlock cable control system is so designed that the selector lever
cannot be shifted from ªPº range position unless the ignition switch
is turned to ªACCº or ªONº position. Also, the ignition key cannot be
pulled out of the key slot unless the selector lever is in ªPº range.
SHIFT LOCK SOLENOID CONTROL OPERATIONS
When the select lever is in ªPº range, the ignition key position is
ªONº and depressing the brake pedal cause the electric current to
flow to the solenoid. As the shift lock solenoid rod (or the lock plate)
is drawn toward the solenoid in this state, it frees the interlock cam
(or the detent pin), which then allows the select lever to be shifted
from ªPº range to any other position.
Even when the select lever is in ªPº range, if the ignition key position
is ªLOCKº or ªACCº or the brake pedal is not depressed, the electric
current does not flow to the solenoid.
In this state, the shift lock solenoid rod (or the lock plate) is pushed
away from the solenoid by spring force and it obstructs the interlock
cam (or the detent pin) movement. Thus the select lever button
does not work even when pressed and the select lever shift is pre-
vented.

SHIFT LOCK (SOLENOID) MANUAL RELEASE
Shift lock can be manually released by following procedure.
1) Remove access hole cover by unfastening screw.
2) Turn ignition key to ªACCº position and move shift lock solenoid
rod (or manual release plate) toward rear side of vehicle by using
screw driver or the like.
3) In this state, select lever can be moved to any range or position.
SYSTEM INSPECTION
1) Check to make sure that select lever cannot be moved to any
other range from ªPº range position when ignition switch key is
at ªACCº position, at ªLOCKº position (or it is removed from key-
hole of ignition switch) or brake pedal is not depressed.
2) Shift select lever to ªPº range position, release knob button and
check for the following.

Ignition key can be turned between ªLOCKº and ªACCº posi-
tions back and forth and also it can be removed from ignition
switch.
