DIFFERENTIAL SIDE OIL SEAL
REPLACEMENT
1) Lift up vehicle and drain transmission oil.
2) Remove drive shaft joints from differential gear of transmis-
sion.
Refer to Section 4 for procedure to disconnect drive shaft
joints.
For differential side oil seal removal, it is not necessary to
remove drive shafts from steering knuckle.
For 4WD vehicle, remove transfer referring to Section 7D.
3) Remove differential side oil seal (1) by using flat end rod or
like.
4) Install new differential side oil seal by using special tool.
Special tool
(A) : 09940-53111
(B) : 09913-75510
5) Install drive shaft referring to Section 4.
6) Refill A/T fluid referring to “FLUID CHANGE” in this section. NOTE:
For oil seal installation, press-fit oil seal so that transmis-
sion case end face is flush with oil seal end face.

AUTOMATIC TRANSMISSION (4 A/T) 7B-69
TRANSMISSION CONTROL MODULE (TCM)
REMOVAL
1) Disconnect negative cable at battery.
2) If the vehicle is equipped with air bag system, disable air bag
system. Refer to “DISABLING AIR BAG SYSTEM” in Sec-
tion 10B.
3) Disconnect couplers from TCM (1) and ECM (2).
4) Loosen bolt and nuts and remove TCM (1) together with
ECM (2) from vehicle.
INSTALLATION
Reverse removal procedure noting the following.
Connect ECM and TCM couplers securely.
If the vehicle is equipped with air bag system, be sure to
enable air bag system after TCM and ECM are back in
place. Refer to “ENABLING AIR BAG SYSTEM” in Section
10B. CAUTION:
TCM and ECM consist of highly precise parts, so when
handling it (or them), be careful not to expose to exces-
sive shock.
NOTE:
When replacing TCM with used one, all learned contents
which are stored in TCM memory should be erased refer-
ring to “LEARNING CONTROL INITIALIZATION” in this
section.

7B-70 AUTOMATIC TRANSMISSION (4 A/T)
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.

SHIFT LOCK SOLENOID MANUAL RLEASE
Without using brake pedal, shift lock can be moved by pushing
shift lock solenoid cam (1) with screw driver or like through hole
(2). (To shift selector lever from “P” range to any other position,
turn ignition switch to “ACC” or “ON” position.)
INSPECTION
1) Check to make sure that selector lever cannot be moved to
any other range from “P” range position when ignition switch
key is at “ACC” position, at “LOCK” position (or it is removed
from keyhole of ignition switch) or brake pedal is not
depressed.
2) Shift selector lever to “P” range position, release knob button
and check for the following.
Ignition key can be turned between “LOCK” and “ACC” posi-
tions back and forth and also it can be removed from ignition
switch.
With shift lock solenoid cam (1) moved in arrow direction and
ignition key turned to “ACC” position, selector lever can be
shifted from “P” range position to any other range.
With shift lock solenoid cam moved in arrow direction and
ignition key turned to “LOCK” position, selector lever can not
be shifted from “P” range position to any other range.

7B-72 AUTOMATIC TRANSMISSION (4 A/T)
When ignition switch is turned “ON” and brake pedal is
depressed, selector lever can be shifted from “P” range posi-
tion to any other range.
3) With ignition lever shifted to any position other than “P”
range, check that ignition key cannot be turned “LOCK” posi-
tion and it cannot be removed from ignition switch unless it is
at “LOCK” position.
KEY INTERLOCK CABLE (IF EQUIPPED)
1. selector lever 3. key inter lock cable
2. knob button 4. key cylinder
NOTE:
Don’t bend interlock cable excessively when removing and installing it, or system will not operate
correctly.
