CAUTION: Vehicle is equipped with Supplemental Restraint System (SRS).
When servicing vehicle, use care to avoid accidental air bag
deployment. SRS-related components are located in steering
column, center console, instrument panel and lower panel on
instrument panel. DO NOT use electrical test equipment on
these circuits. If necessary, deactivate SRS before servicing
components. See AIR BAG SERVICING article in APPLICATIONS &
IDENTIFICATION.
DESCRIPTION
Automatic transmission is a 4-speed electronically controlled
transmission. Solenoids that control shift changes are located in
valve body. Solenoids are controlled by a Transmission Control Module
(TCM). TCM receives information from various input devices and uses
this information to control shift solenoids for transmission shifting
and lock-up solenoid for torque converter lock-up.
An Overdrive (OD) switch is mounted on the shift lever. When
OD switch is depressed to ON position, transmission will shift into
4th gear when shift lever is in "D" position, and OD OFF light on
instrument panel will go off. When OD switch is released to OFF
position, transmission will shift into 3rd gear, and OD OFF light on
instrument panel will illuminate.
A pattern select switch is located near shift lever on center
console. Pattern select switch contains a NORMAL and a HOLD operating
position. When pattern select switch is depressed (HOLD position) with\
shift lever in Drive position, transmission starts in 2nd gear.
Upshifts and downshifts will occur at a higher vehicle speed than with
switch in NORMAL position. See MITSUBISHI R4AW3 & V4AW3 OVERHAUL
article. Indicator light on instrument panel indicates pattern select
switch is in HOLD position.
Transmission is equipped with a shift lock and key interlock
system. Shift lock system prevents shift lever from being moved from
Park unless brake pedal is depressed. Key interlock system prevents
ignition key from being moved from ACC to LOCK position on ignition
switch unless shift lever is in Park. See MITSUBISHI SHIFT LOCK
SYSTEMS article.

DESCRIPTION
Shift interlock system inhibits shift selector lever movement
from "P" to drive ranges unless brake pedal is depressed. Key
interlock system prevents ignition switch turning to LOCK position
unless shift selector lever is in "P" position.
TESTING
KEY INTERLOCK SYSTEM
1) With ignition switch in LOCK position and brake pedal
depressed, ensure selector lever cannot be moved from "P" to any other
position. Ensure selector lever button cannot be pushed. With ignition
switch in ACC position, brake pedal depressed and selector lever
button pushed, ensure selector lever can be moved from "P" position to
any other position. Ensure selector lever moves smoothly.
2) Ensure ignition key cannot be turned to LOCK position at
all selector lever positions other than "P". Ensure ignition key turns
smoothly to LOCK position when selector lever is set to "P" and
selector lever button is released. If key interlock system is not as
specified, adjust key interlock cable. See KEY INTERLOCK CABLE under
ADJUSTMENTS.
SHIFT LOCK SYSTEM
1) With ignition switch in ACC position, brake pedal released
and selector lever button pushed, ensure selector lever cannot be
moved from "P" to any other position. With ignition switch in ACC
position, brake pedal depressed and selector lever button pushed,
ensure selector lever can be moved from "P" position to any other
position.
2) With selector lever in "R" position, ignition switch in
ACC position, brake pedal released and selector button pushed, ensure
selector lever can be moved from "R" to "P" position. If shift lock
system is not as specified, adjust shift lock cable. See SHIFT LOCK
CABLE under ADJUSTMENTS.
ADJUSTMENTS
KEY INTERLOCK CABLE
3000GT
Remove front console assembly. Move selector lever to "P".
Loosen nut securing key interlock cable. Gently press lock cam "A"
down while pushing cable to take up slack. See Fig. 1. Tighten nut to
specifications to secure cable. See TORQUE SPECIFICATIONS.

The following

COMPUTER RELEARN PROCEDURES
1998 Mitsubishi Montero
GENERAL INFORMATION
Computer Relearn Procedures
All Models
* PLEASE READ THIS FIRST *
The following general procedures are to be used if
driveability problems are encountered after power loss or battery has
been disconnected. These procedures may provide an aid in eliminating
these problems.
To reduce the possibility of complaints, after any service
which requires battery power to be disconnected, vehicle should be
road tested.
COMPUTER RELEARN PROCEDURES
Vehicles equipped with engine or transmission computers may
require a relearn procedure after vehicle battery is disconnected.
Many vehicle computers memorize and store vehicle operation patterns
for optimum driveability and performance. When vehicle battery is
disconnected, this memory is lost. The computer will use default data
until new data from each key start is stored. As computer memorizes
vehicle operation for each new key start, driveability is restored.
Vehicle computers may memorize vehicles operation patterns for 40 of
more key starts.
Customers often complain of driveability problems during
relearn stage because vehicle acts differently then before being
serviced. Depending on type and make of vehicle and how it is
equipped, the following complaints (driveability problems) may exist:
* Harsh Or Poor Shift Quality
* Rough Or Unstable Idle
* Hesitation Or Stumble
* Rich Or Lean Running
* Poor Fuel Mileage
These symptoms and complaints should disappear after a number
of drive cycles have been memorized. To reduce the possibility of
complaints, after any service which requires battery power to be
disconnected, vehicle should be road tested. If a specific relearn
procedure is not available, the following procedure may be used:
Automatic Transmission
* Set parking brake, start engine in "P" or "N" position.
Warm-up vehicle to normal operating temperature or until
cooling fan cycles.
* Allow vehicle to idle for one minute in "N" position. Select
"D" and allow engine to idle for one minute.
* Accelerate at normal throttle position (20-50%) until vehicle
shifts into top gear.
* Cruise at light to medium throttle.
* Decelerate to a stop, allowing vehicle to downshift, and use
brakes normally.
* Process may be repeated as necessary.
Manual Transmission

Page 269 of 1501

MITSUBISHI MONTERO 1998 Service Manual * Place transmission in Neutral position.
* Ensure emergency brake has been set and all accessories
are turned off.
* Start engine and bring to normal operating tempera
