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.

DISASSEMBLY/ASSEMBLY OF SUBASSEMBLY
OIL PUMP
CAUTION:
 Keep component parts in group for each subassembly and avoid mixing them up.
 Clean all parts with cleaning solvent thoroughly and air dry them.
 Use kerosene or automatic transmission fluid as cleaning solvent.
 Do not use wiping cloths or rags to clean or dry parts.
 All oil passages should be blown out and checked to make sure that they are not obstructed.
 Keep face and eyes away from solvent spray while air blowing parts.
 Check mating surface for irregularities and remove them, if any, and clean it again.
 Soak new clutch discs and brake discs in transmission fluid for at least 2 hours before assembly.
 Replace all gaskets and O-rings with new ones.
 Apply automatic transmission fluid to all O-rings.
 When installing seal ring, be careful so that it is not expanded excessively, extruded or caught.
 Replace oil seals that are removed and apply grease to their lips.
 Before installing, be sure to apply automatic transmission fluid to sliding, rolling and thrusting sur-
face of all component part. Also after installation, make sure to check each part for proper opera-
tion.
 Always use torque wrench when tightening bolts.

Check each lip for wear, deformation, cut, and/or hardening. If
necessary, replace.
NOTE:
 If disc lining is exfoliated or discolored, replace all
discs.
 Before assembling new discs, soak them in A/T fluid
for at least two hours.
NOTE:
 Do not apply excessive force when measuring spring
height.
 Perform measurement at several points.
