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.

3) If selector lever is in “P” range, shift selector lever to other
than “P” range with releasing shift lock referring to “SHIFT
LOCK SOLENOID MANUAL RELEASE” in this section.
4) Install cable end (1) and cable casing cap (2) to key interlock
cam (3) and its bracket (4), then install cable (5) to selector
pad (6).
5) With selector lever set at “P” position, turn ignition key to
“ACC” position and then check for following conditions.
With knob button released, ignition key can be turned from
“ACC” position to “LOCK” position.
With knob button pressed, ignition key cannot be turned from
“ACC” position to “LOCK” position.
6) Install steering column referring to Section 3C.
7) Install steering column hole cover.
8) Install center console.
9) Connect negative cable at battery and enable air bag sys-
tem, referring to “ENABLING AIR BAG SYSTEM” in Section
10B (if equipped).

7B-80 AUTOMATIC TRANSMISSION (4 A/T)
12) Disconnect couplers from solenoid valves, and transmission
temperature sensor.
Remove transmission temperature sensor.
13) Remove valve body assembly (1).
14) Remove solenoid harness assembly.
15) Remove accumulator pistons and springs.
To remove C0 (1), C2 (2) and B1 (3) accumulator pistons
and springs, position a rag on pistons to catch each piston.
To remove pistons, force low-pressure compressed air (1 kg/
cm
2, 15 psi, 100 kPa, max) into hole (4) as shown in figure,
and pop each piston into the rag.
To remove B0 and C1 accumulator pistons and springs,
remove each snap ring and accumulator spacer, then
remove spring and piston.
16) Remove torque converter housing (1).
a) Remove housing bolts.
b) Remove housing while tapping around it lightly with a plas-
tic hammer. CAUTION:
Be careful not to let manual valve fall off when removing
valve body assembly.
NOTE:
There are three kinds of bolts (bolts A, B and C) fixing
valve body assembly.
2. Bolt A
3. Bolt B
4. Bolt C
NOTE:
Do not push accumulator pistons with fingers or any-
thing before removing them. Pushing them may cause
compressed fluid in accumulator to spew out of hole and
get to your face and clothes.
NOTE:
Never reuse bolts A shown in figure.
