AUTOMATIC TRANSMISSION -Troubleshooting AUTOMATIC TRANSMISSION -Troubleshooting 23-51
Inspection procedure 5
Does not move (forward or reverse)
Probable cause
If the vehicle does not move forward or reverse when the selector lever is
moved to any position while the engine is idling, thecause is probably a
problem with line pressure or a malfunction of the oil pumps and valve bodies in
the power train.DAbnormal line pressure
DMalfunction of power train components
DMalfunction of oil pump
DMalfunction of valve body
DMalfunction of engine-A/T-ECU <6G7>
DMalfunction of A/T-ECU<4M4>
LRefer to the Transmission Workshop Manual.
Fluid pressure test (Refer to P.23-106.)
DMeasure the fluid pressure at each element in 1st, 2nd
and reverse.
Standard value:Refer to P.23-106.OKCheck the power train components
L
DDisassemble the transmission and check the condition of
components such as the planetary carrier, output shaft and
differential.
NG
Replace the oil pumpassembly.
L
(The oilpump cannot be disassembled.)
Disassemble, clean and re-assemble the valve body.
L
DMake sure that the mounting bolts are not loose and that
the O-ring and valve body are notdamaged or positioned
incorrectly.
DIf the extent of thedamagelooks too bad for repairs to be
carried out, replace the valve body assembly.NG
NG
Check the trouble symptoms.
Replace the engine-A/T-ECU or A/T-ECU.
Inspection procedure 6
Engine stalls during shifting
Probable cause
If the enginestalls when the selector lever is moved from N to D or R while the
engine is idling, thecause is probably a malfunction of theenginesystem, DCC
solenoid valve, valve body, or torque converter (damper clutch).DMalfunction of enginesystem
DMalfunction of DCC solenoid valve
DMalfunction of valve body
DMalfunction of torque converter (malfunction of
damper clutch)
DMalfunction of engine-A/T-ECU <6G7>
DMalfunction of A/T-ECU<4M4>
LRefer to the Transmission Workshop Manual.
Engine system check
DControl system, ignition system, fuel system, vehicle bodyNG
Repair or replace
OK
Replace the DCC solenoid valve.
L
Disassemble, clean and re-assemble the valve body.

REAR AXLE -General Information27-2
GENERAL INFORMATION
The rear axle has the following features.
DD.O.J.-type on the differential side and B.J.-type on the hub side constant velocity joints are featured
in the drive shaft.
DLarge capacity and high rigidity taper-roller type unit bearing in the wheel bearing is featured.
DThe hybrid LSD and differential lock with LSD which benefit driving on muddy and rough roads are
featured as an option.
DABS rotor to detect wheel speed is press-fitted in the drive shaft.
NOTE
The structure of normal differential and hybrid LSD is basically the same as featured in existing models.

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and passenger (from rendering
the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any SRS-related
component.
NOTE
The SRS includes the following components: SRS-ECU, SRS warning lamp, air bag module, clock spring and interconnecting
wiring. Other SRS-related components (that mayhave to be removed/installed in connectionwith SRS service or maintenance) are
indicated in the table of contents by an asterisk(*).
