2003 SSANGYONG MUSSO low oil pressure

AUTOMATIC TRANSMISSION 5A-65
If the gear lever is incorrectly adjusted, the transmission may shift gears on bumpy road surfaces.
6 Transmission Oil Temperature Sensing FaultAll shifts will be firm until the transmission has warmed up, because a high transmission oil temperature is
assumed.
If a fault is undetected, the temperature is likely to be evaluated as being lower than actual, resulting in softer shifts with ‘end bump ’ (very firm feel at the end of the shift).
7 Mode Setting Fault All shifts will occur as if the mode is set to ‘NORMAL ’ .
The mode indicator will always be off indicating that ‘NORMAL ’ mode is selected.
The mode indicator will not respond to changes in switch setting.
If a fault is undetected, the mode as indicated by the mode indicator is not likely to respond to the mode switch.
8 Battery Voltage Sensing Fault
If the battery voltage is low then shifts to first gear are inhibited.9 the battery voltage is high (>16.5V) then the transmission goes into limp home (LHM) mode.
If a fault is undetected, the transmission is likely to incorrectly evaluate an ON/OFF solenoid fault resulting in limp home mode (LHM) operation.
9 ON/OFF Solenoid Fault (Solenoids 1,2,3 and 4)
The transmission adopts its limp home mode (LHM) operation, described above. However, if solenoid 1 is faulty then
the fourth gear LHM strategy will be adopted independent of vehicle speed.
If a fault is undetected, the operation of the transmission is dependent on which solenoid is actually faulty. The
characteristics for different solenoid fault conditions are listed in table 6.1.2.
10 ON/OFF Solenoid Fault (Solenoids 6,7)
If solenoid 6 is found faulty it is always disabled resulting in high line pressure being applied continuously.
If solenoid 7 is found faulty it is disabled resulting in the transmission being locked always.The transmission does not go into LHM.
11 Variable Pressure Solenoid Fault The transmission adopts its LHM operation.
If a fault is undetected, the transmission shift feel is likely to be poor for all shifts.
12 Software Fault
The transmission adopts the third gear LHM strategy of operation, independent of vehicle speed. The operation of
the TCU under this condition is difficult to predict. Its operation may be erratic.
If a fault is undetected, the operation of the TCU is likely to be erratic.
13 Power Supply Fault
The transmission adopts the third gear LHM strategy of operation, independent of vehicle speed. If there is an
intermittent power supply connection, the TCU will power-up in fourth gear and then shift to the appropriate gear to
satisfy the conditions present. The power supply is not monitored for fault evaluation.
All faults except for solenoid faults can be recovered without having to turn the TCU off and back on. However, in
general the recovery requires that no faults are present for a period of time (approx. 3 or 30 seconds). Recovery from
a fault will not clear the fault from the keep alive memory
14 Transmission Sump Temperature Exceeding 135°C
The converter lockup clutch will be applied at lower speeds, causing a shudder through the vehicle.
The mode indicator will flash in some vehicles.
These faults can be due to the transmission oil overheating or due to an incorrect signal received from the temperature
sensor.

Oil Filter and Pan Assembly Notice
1. Replace the filter whenever rebuilding a transmission where a significant amount of mechanical damage hasoccurred.
2. To aid the assembly of the pan gasket, use a small amount of Vaseline at the pan/gasket interface. This ensures that the gasket remains on the pan ridge. Do not over torque pan bolts as this may distort the pan and cause leaks.
3. Ensure that the internal line pressure plus in the valve body is fitted.
To assemble the oil filter and pan assembly (refer to figures 8.63 and 8.64), proceed as follows.
1. Lubricate the oil filter sealing ring with automatic transmission fluid.
2. Carefully assemble the oil filter to the valve body. The spigot must not lean on one side while being fitted. Refer to figure 8.63.
3. Secure the oil falter assembly with the retainer.
4. Check that the magnet is located in the dimple in the comer of the oil pan.
5. Assemble the gasket on the pan lip. The gasket must be free of any distortion when installed.
6. Fit the oil pan assembly to the transmission case and tighten the securing bolts to specification and sequence (refer to figure 8.65). Do not over torque.

5. Unscrew the bolts and remove the clutch cover, pressure
plate and clutch disc. NoticeBe careful not to drop the pressure plate and clutch disc.Installation Notice
Tightening Torque 21 - 27 Nm
6. Installation should follow the removal procedure in the reverse order. Notice
Before installation, clean oil and grease on the flywheel surface.
Do not clean the clutch disc and release bearing insolvent.

5D1-22 TRANSFER CASE (PART TIME 4408) Cleaning Procedure Notice Before cleaning, check the magnet for thepresence of metal particles which indicate internalchipping of the transfer case.
1. Using cleaning solvent, clean the residual oil and dirtdeposits.Notice
During cleaning, be careful not to damage the metal surfaces.
2. After cleaning, dry the parts with low pressure (Max. 20 psi) compressed air.
3. Lubricate the ball bearings and needle bearings with transfer case oil after cleaning. NoticeProtect the lubricated bearings from dust.
Inspection Procedure
1. Visually check the all removed parts. Notice
Always replace the hose coupling, O-ring and oil seal with new parts.
2. Inspection Terms Burr : Local rise of material forming protruding sharp
edge
Chip : An area from which a small fragment has been
broken off or cut
Crack : Surface break of line nature indicating partial or
complete separation of material.
Excessive wear : Heavy or obvious wear beyond
expectations considering conditions of operation.
Indentation : Displacement of material caused by localized
heavy contact.
Galling : Breakdown of metal surface due to excessive
friction between parts. Particles of the softer materialare torn loose and welded to the harder material.
Nick : Local break or notch, usually displacement of
material rather than loss.
Scoring : Tear or break in metal surface from contact
under abnormal pressure.
Step wear : Heavy wear that produces a step that can
be seen or felt between adjacent contact and noncontactsurfaces.
Uneven wear : Condition of localized, unevenly distributed
wear Includes hollows, shiny spots, uneven polish and other visual indications.
