3) Run at "D" range lock-up or OD gear and check for
abnormal noise and vibration.
NOTE:
The check for the cause of abnormal noise and vibration
must be made with extreme care as it could also be due to
loss of balance in the propeller shaft, differential, the
torque converter, etc. or insufficient bending, rigidity, etc.
in the power train.
4) While running in "D" range, 2nd, 3rd gears and OD, check
to see that the possible kick-down vehicle speed limits for 2
1, 3 1, 3 2, OD 3 and OD 2 kick-downs
conform to those indicated on the automatic shift diagram.
5) Check for abnormal shock and slip at kick-down.
6) While running in "D" range, OD gear or "lock-up", shift to
"2" and "L" ranges and check the engine braking effect at
each of these ranges.
7) Also check to see that downshift is made from 3
2 or
from OD to 3 and then to 2 immediately and that 2
1
downshift point is within the limits shown in the diagram
when tested by releasing the accelerator pedal and shifting
into position of "L" while driving in the third gear or in
overdrive.
EVALUATION
(1) If there is no engine braking effect in the "2" range:
• Second coast (No. 1) brake is defective.
(2) If there is no engine braking effect in the "L" range:
• First and reverse (No. 3) brake is defective
(3) Also check to see that downshift is made from 3
2 or
from OD to 3 and then to 2 immediately and that 2
1
downshift point is within the limits shown in the diagram
when tested by releasing the accelerator pedal and shifting
into "L" position while driving in the third gear or in
overdrive.

NEUTRAL START SWITCH INSPECTION
Inspection
With a circuit tester, make a continuity test on the neutral star t
switch with the moving piece set in each position.
Continuity
Removal
Preparation:
Disconnect negative (–) battery cable.
1. Remove rear sound cover.
2. Remove the rear side ATF cooler pipe from the
transmission elbow.
3. Disconnect neutral star t switch connector.
4. Unstake the lock washer, and then remove the shaft nut.
5. Remove the neutral start switch.
Installation
To install, follow the removal steps in the reverse order, noting
the following points;
Adjustment
1) Loosen the neutral star t switch bolt and set the shift
selector to the "N" range.
2) Align the groove and neutral basic line.
3) Hold in position and tighten the bolt.Te r m i n a l

Look-up solenoid (Normal open type)
THROTTLE POSITION SENSOR
INSPECTION
1. Turn the starter switch to the "ON" position.
2. Measure the voltage between throttle position sensor
connector terminals 2 (output) and 3 (ground).
NOTE:
• Do not remove the sensor connector.
• Make sure that power source (4.75-5.25V) is measured
between terminals 1 and 3 before measurement at step
2).
ATF TEMPERATURE SENSOR
INSPECTION
1. Disconnect the front side ATF cooler pipe from the elbow
and remove the elbow.
2. Remove the ATF temperature sensor from the transmission
case.
3. Place the ATF temperature sensor in a container of ATF.
4. Measure the resistance between each terminals.
5. If either of the measured values exceeds the specified,
replace the ATF temperature sensor.

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)

NOTE:
1. 2 or 3 people are reguired removal and installation of the
valve body assembly and pressure control solenoid.
2. The check valve assembly (1) and the C0 accumulator
piston springs (2) will fall from the transmission case during
removal of valve body assembly.
Protect these parts from damage.
The B0 (3), C2 (4), and B2 (5) accumulator piston and
springs may also fall free and must be protected.

INSTALLATION
To install, follow the removal steps in reverse order, noting the
following points;
1. Reinstall the par ts removed with the valve body assembly
to their assigned positions in the transmission case (check
valve assembly, C0 accumulator pistons, etc). Install the
valve body assembly to the transmission case.
Refer to
“REASSEMBLY OF MAJOR COMPONENTS (2).”
