HYDRAULIC TEST
PREPARATION
1) Warm up the transmission fluid.
2) Remove the transmission case test plug and mount the
hydraulic pressure gauge.
Oil pressure gauge: 5-8840-0093-0
NOTE:
Perform the test at normal operating fluid temperature (50
– 80
C or 122 – 176F).
MEASURE LINE PRESSURE
1) Fully apply the parking brake and chock the four wheels.
2) Start the engine and check idling rpm.
3) Shift into "D" range, step down strongly on the brake pedal
with your left foot and, while manipulating the accelerator
pedal with the right foot, measure the line pressures at the
engine speeds specified in the table.
4) In the same manner, perform the test in "R" range.
EVALUATION
1) If the measured values at all ranges are higher than
specified.
• Pressure control solenoid defective.
• Primary regulator valve defective.
2) If the measured values at all ranges are lower than
specified.
• Primary regulator valve defective.
• Oil pump defective.
• Pressure control solenoid defective.
3) If pressure is low in "D" range only:
• "D" range circuit fluid leakage.
4) If pressure is low in "R" range only:
• "R" range circuit fluid leakage. Engine

TRANSIMISSION FLUID LEVEL AND
CONDITION
Park vehicle on level ground and set parking brake.
With the engine idling, move the shift lever through all
positions from "P" to "L", then return to position "P".
Check to see If the level of fluid comes to "HOT" range
of about 80
C (176F) on the dipstick gauge.
If the level of fluid is too low, replenish to bring it to
maximum level in "HOT" range.
Inspection of fluid condition
If the ATF is black or smells burnt, replace it.
ATF REPLACEMENT
NOTE:
Do not overfill.
1) Remove the drain plug from oil pan and drain the
fluid.
2) Reinstall the drain plug securely.
3) With the engine OFF, add new fluid through the filler
tube.
4) Star t the engine and shift the selector into all
position from "P" through "L", and then shift into "P".
5) With the engine idling, check the fluid level. Add fluid
up to the "COLD" level on the dipstick.
6) The ATF level must be checked again for correct
level with the "HOT" level.
NOTE:
To prevent fluid leaks, the drain plug gasket must be
replaced each time this plug is removed.

PATTERN SELECT SWITCH INSPECTION
Inspect that there is continuity between each terminals.
OVERDRIVE OFF SWITCH INSPECTION
Inspect that there is continuity between terminals 2 and 4.
SOLENOID INSPECTION
1. Resistance check
• Using an ohmmeter, check the resistance between each
terminals (S1/S2/SL) and body.
• Using an ohmmeter, check the resistance between
terminals (STH) and (STHG).

NOTE:
If the pressure contorl solenoid resistance is not within
specification, replace the valve body assembly.
2. Operation Check
Check the solenoid operation by blowing into an oil hole as
shown in the figure.

INSTALLATION
To install, follow the removal steps in the reverse order, noting
the following points;
Adjustment of select lever and control rod
1) Place the vehicle on a level surface.
NOTE:
If the vehicle is not on a level surface, the shift select cable
set position will vary with the movement of the engine. To
prevent possible misadjustment of the cable, the vehicle
must be placed on a level surface.
2) Install the shift control rod (1) to the transfmission select
lever (2), and then place the lever in the "N" position.
3) Set select lever in the "N" position.
4) Push select lever forward and secure it (using a rubber
band (3), etc.) so that pin comes into contact with the wall
of detent plate.
5) Install the shift control rod (1) to the selector lever arm (4).
NOTE:
Do not apply to threaded portions.
6) After adjustment, operate select lever on a trial basis to
makes sure of its smooth operation and no abnormal
indication in each position.
Adjustment of shift lock cable
1) Set ignition key in "LOCK" position and selector lever in "P"
position.
2) Adjust cable screw cap on selector lever side to provide a
gap (slack for cable) of 1–2mm between rod on steering
lock side and stopper.
Adjust cap as follows:
a. Pull screw cap (1) in arrow direction to put off slack of
inner cable.
b. With cable kept as (a), adjust gap between nut (2) and
bracket to 5mm (0.2in).
c. Lock inner cable by tur ning nut (3) while holding nut (2) in
place.
NOTE:
Clean the rod threads and do not apply oil to the threaded
portions.Nꞏm(kgꞏm / lbꞏft)
