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 level surface, the shift
select cable set positions will vary with the movement of
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 transmission
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 (“R” position side) and
s e c u r e i t ( u s i n g a r u b b e r b a n d ( 3 ) , e t c . ) s o t h a t t h e p i n
comes into contact with the wall of the detent plate.
5. Install the shift control rod (1) to the selector lever arm

6. After adjustment, make sure that the selector lever
operates normally, and that each selector position is
properly indicated. (The red mark shows through the
window.)
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 – 2 mm between
rod on steering lock side and stopper.
Adjust cap as follows:
a. Pull screw cap (1) in arrow direction to remove
inner cable slack.
b. With cable kept as (a), adjust gap between nut (2)
and bracket to 5 mm (0.2 in).
c. Lock inner cable by turning nut (3) while holding nut
(2) in place.

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.

SELECTOR LEVER
INSPECTION
1. Make sure that when the selector lever is shifted from "P" to
"L", a "clicking" can be felt at each shift position. Make sure
that the gear corresponds to that of the position plate
indicator.
2. Check to see if the shifter lever can be shifted as shown.
