AUTOMATIC TRANSMISSION (4 A/T) 7B-59
INSTALLATION
1) Using flat tip screwdriver, turn transmission range sensor to
have the match marks (1) line up (transmission range sensor
“N” range).
2) Turn selector lever (1) to “N” range (to have the automatic
transmission to “N” range).
3) Install transmission range sensor (1) to transmission case.
Tightening torque
Transmission range sensor bolt
(a) : 18 N·m (1.8 kg-m, 13.0 lb-ft)
4) Move selector lever in cabin to each range and check the
continuity of each terminal of transmission range sensor
referring to “INSPECTION”.
5) Connect transmission range sensor coupler.
6) Check that the engine can only be started in “N” and “P”
range, but can not in “D”, “2”, “L” or “R” range. Also, check
that backup lamp come ON at “R” range.

LEARNING CONTROL INITIALIZATION
When one or more operations such as shown below are per-
formed, all learned contents which are stored in TCM memory
should be erased after the operations.
Replacing transmission with new or used one.
Repairing transmission partially by replacing any brake com-
ponent parts with new and/or used brake disc(s), plate(s)
and/or flange.
Repairing transmission partially by replacing any clutch com-
ponent parts with new and/or used clutch disc(s), plate(s)
and/or flange.
Replacing TCM with used one.
1) Turn ignition switch ON, leaving engine OFF.
2) Using service wire, connect diagnosis switch terminal (2)
with ground terminal (3) of monitor connector No.2 (1).
3) Shift selector lever from “D” range to “2” range 3 times
repeatedly within 10 seconds with diagnosis switch terminal
(2) kept on connecting with ground.
4) Check DTC referring to “DTC CHECK” in this section and
confirm that only DTC No.12 is displayed.
If not, repeat Step 1) to Step 3) and check again.
BRAKE INTERLOCK SYSTEM (IF EQUIPPED)
SHIFT LOCK SOLENOID CONTROL
This system consists of shift lock solenoid control system and
interlock cable control system.
The shift lock solenoid control system is so designed that the
selector lever can not be shifted from “P” range position unless
ignition switch is turned ON and the brake pedal is depressed.
And interlock cable control system is so designed that select lever
cannot be shifted from “P” range position unless ignition switch is
turned to “ACC” or “ON” position. Also, ignition key cannot be
pulled out of key slot unless selector lever is in “P” range. NOTE:
 “O/D OFF” lamp lights during initializing.
 Diagnostic trouble code(s) (DTC(s)) also are erased by
performing this initializing procedure.
 After initializing is achieved, DTC No.12 is stored in
TCM. If initializing is failed, DTC No.52 is stored in
TCM.

INSPECTION
Inspect clutch cable and replace it for any of the following condi-
tions.
Excessive cable friction
Frayed cable
Bent or kinked cable
Broken boots
Worn end
INSTALLATION
1) Apply grease to cable end hook and also joint pin before
installing cable.
“A” : Grease 99000-25010
2) Hook cable end with pedal by using screwdriver or long nose
pliers from cabin inside, then join inner cable wire joint pin in
release lever.
3) Install clutch cable (2) to bracket (3) by turning cable cap (1)
about 90° as shown.
4) Screw in joint nut and adjust free travel of pedal to specifica-
tion by turning nut.
5) Check clutch for proper function with engine running.
NOTE:
Take care that cable grommet (4) has specific installing
direction as shown in the figure.

CLUTCH 7C-7
CLUTCH PEDAL HEIGHT
Adjust clutch pedal (1) height with adjusting bolt (2) located on
pedal bracket (3) so that clutch pedal height is same as brake
pedal (4) height.
Height difference
“a” : 0 mm (0 in.)
CLUTCH PEDAL FREE TRAVEL
1) Confirm that clutch pedal height is specification.
2) Depress clutch pedal (1), stop the moment clutch resistance
is felt, and measure distance (clutch pedal free travel). Free
travel should be within the following specification.
Pedal free travel
“b” : 15 – 20 mm (0.6 – 0.8 in.)
3) If free travel is out of specification, adjust it with cable joint
nut (1).
Release lever free travel (Reference)
“c” : 0 – 2 mm (0 – 0.08 in.)
4) After checking clutch pedal free travel, also check clutch for
proper function with engine running.
