1991 MITSUBISHI MONTERO clock

Remove horn pad and steering wheel. See Figs. 1-6. See
STEERING COLUMN TESTING/REMOVAL & INSTALLATION table for figure
directory on specific model. Remove knee protector and upper and lower
column covers (if necessary). On Eclipse, remove hood lock release
handle and air ducts. On all models, remove any necessary cable bands,
and remove steering column switch. To install, reverse removal
procedure.
Removal (Stealth & 3000GT)
1) Disconnect negative battery cable. Wait 30 seconds, and
then remove air bag module mounting nut from back side of module. To
remove clockspring connector from air bag module, force lock outward
and pry it using a flat screwdriver. Ensure no undue force is exerted
on connector when it is removed. Remove air bag module, and store it
face up. See Fig. 7.
CAUTION: Wait at least 30 seconds after disconnecting battery cable
before continuing servicing.
2) Remove steering wheel and knee protector. Remove upper and
lower column covers. Remove air ducts. Remove right and left steering
column switches.
WARNING: DO NOT hammer on steering wheel. Collapsible steering column
mechanism may be damaged.
Installation
1) To install, reverse removal procedure. Before installing
steering wheel, center clockspring by lining up NEUTRAL mark of
clockspring with mark on steering column. To complete installation,
reverse removal procedure. DO NOT reconnect negative battery cable
until air bag module is installed.
2) After installation is complete, turn ignition on from
passenger side of vehicle. Supplemental Restraint System (SRS) light
on dash should come on for approximately 7 seconds. If SRS light does
not come on, stays on or flashes, repair air bag system.

fluid to bring level to lower mark of dipstick if necessary. Recheck
fluid level after transmission is at normal operating temperature.
TRANSFER CASE
Drain plug is located on bottom of transfer case. Change
drain plug gasket whenever fluid is changed. On 3000GT, lubricant
level should be approximately .5" (13 mm) below fill hole on side of
transfer case. On all others models, lubricant level should be to
bottom of fill hole on side of transfer case.
HYDRAULIC CONTROL PRESSURE ADJUSTMENTS
LINE PRESSURE CHECK (EXCEPT MONTERO & PICKUP)
1) Set parking brake. Place shift lever in Neutral position.
Attach engine tachometer. Remove line pressure port plug located above
front transaxle shaft, forward of governor pressure port plug. On
Precis, line pressure port is located below bell housing, at front of
transaxle oil pan. Using appropriate adapter, attach pressure gauge.
2) Start engine, and bring to operating temperature. With
gear selector in Drive position, bring engine speed to 2500 RPM. Pull
throttle control cable (if equipped) wide open at transaxle side.
3) Line pressure should be 98-100 psi (6.9-7.0 kg/cm
) on
Mirage, or 124-127 psi (8.7-8.9 kg/cm) on all others. If line
pressure is not to specification, proceed to LINE PRESSURE ADJUSTMENT.
LINE PRESSURE ADJUSTMENT (EXCEPT MONTERO & PICKUP)
1) Drain transaxle fluid. Remove oil pan. Disconnect throttle
control cable from throttle cam. Remove oil temperature sensor (if
equipped). Disconnect solenoid connector. On some models, it may be
necessary to push solenoid wire harness connector and grommet into
transaxle case.
2) Remove oil filter screen and plate. Noting location and
length of bolts, remove valve body. DO NOT drop internal parts. Adjust
line pressure by turning regulator valve adjusting screw.
3) Turn adjusting screw counterclockwise to increase pressure
or clockwise to decrease pressure. One complete turn of adjusting
screw changes line pressure as follows.
* 3.7 psi (.26 kg/cm
) on Mirage with F3A21 Transaxle
* 5.4 psi (.39 kg/cm) on Precis
* 54 psi (3.8 kg/cm) on all others
4) After adjustment, reverse removal procedure to install.
Refill transaxle.
LINE PRESSURE (MONTERO)
1) Remove plug from line pressure take-off port located
behind transmission shift control lever. Install Hydraulic Pressure
Meter (MD998330) with Adapter (MD998206).
2) Place vehicle on dynamometer. Apply parking brake and
start engine. With brake applied, place transmission in Drive. Note
pressure at idle. Pressure should be 74-85 psi (5.2-6.0 kg/cm
).
3) Raise engine RPM to stall speed (2100-2400 RPM). Note lin\
e
pressure. Pressure should be 156-185 psi (11.0-13.0 kg/cm
).
4) Shift transmission into Reverse with brake applied. At
idle, pressure should be 112-130 psi (7.9-9.1 kg/cm
). Raise engine
RPM to stall speed (2100-2400 RPM). Note line pressure. Pressure
should be 227-285 psi (16.0-20.0 kg/cm
). If readings are not to

specification, use the following trouble shooting guide.
* Hydraulic Pressure High In All Ranges
Check throttle cable adjustment. If adjustment is okay, check
for throttle valve or regulator valve failure.
* Hydraulic Pressure Low In All Ranges
Check throttle cable adjustment. If adjustment is okay, check
for throttle valve, regulator valve, transmission oil pump or
overdrive clutch failure.
* Hydraulic Pressure Low In Drive Position
Check for fluid leaks in Drive hydraulic circuit. Check for
forward clutch or overdrive clutch failure.
* Hydraulic Pressure Low In Reverse Position
Check for fluid leaks in Reverse hydraulic circuit. Check for
transmission No. 3 brake failure, forward clutch failure or
overdrive clutch failure.
LINE PRESSURE (PICKUP)
1) Incorrect throttle pressure setting will cause incorrect
line pressure readings even though line pressure adjustment is
correct. Always inspect and correct throttle pressure adjustment
before adjusting line pressure.
2) Approximate adjustment, measured from valve body to inner
edge of adjusting nut, is 15/16". However, due to manufacturing
tolerances, adjustment can be varied to obtain correct line pressure.
3) Adjusting screw may be turned with an Allen wrench. One
complete turn of adjusting screw changes closed throttle line pressure
approximately 1 2/3 psi. Turn adjusting screw counterclockwise to
increase pressure or clockwise to decrease pressure.
THROTTLE PRESSURE (PICKUP)
1) Throttle pressures cannot be accurately tested. If a
malfunction exists, adjustment should be measured.
2) Insert Gauge Pin (C-3763) between throttle lever cam and
kickdown valve. Push in on tool to compress kickdown valve against its
spring.
3) As force is being exerted to compress spring, turn
throttle lever screw with Allen wrench until head of screw touches
throttle lever tang with gauge pin, and throttle valve bottoms. Ensure
adjustment is made with spring fully compressed and valve bottomed in
valve body.
KICKDOWN BAND
PICKUP
1) Locate kickdown band adjusting screw on left side of
transmission case. Loosen lock nut, and back off nut 5 turns. Ensure
adjusting screw turns freely in transmission case.
2) Using torque wrench, tighten adjusting screw to 72 INCH
lbs. (8 N.m). Back off adjusting screw 2 7/8 turns. Hold adjuster
screw in this position, and tighten lock nut to 30 ft. lbs. (41 N.m).
LOW-REVERSE BAND
PICKUP
1) Raise vehicle, drain transmission, and remove oil pan.
Loosen adjusting screw lock nut, and back off nut 5 turns. Ensure
