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.
REMOVAL
Preparation:
Diconnect negative (–) battery cable.
1. Transfer Control Lever Knob
2. Front Console

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)

3) Make sure of proper operation of shift lock through checks
as follows:
a. Selector lever shall not be moved out of "P" position with
ingition key in "Lock" position.
b. Selector lever can be moved out of "P" position with
ignition key in "ON" position only when brake pedal is
depressed.
c. Ignition key can be turned to "LOCK" position only when
selector lever is in "P" position (key can be pulled out).
If (a) and (c) fail, readjust cable. If (b) fails, readjust
connector wiring and brake pedal switch.
