DIAGNOSIS
OIL LEAK DIAGNOSIS
Most fluid oil leaks are easily located and repaired by
visually finding the leak and replacing or repairing the
necessary parts. On some occasions a fluid leak may be
difficult to locate or repair. The following procedures may
help you in locating and repairing most leaks.
Finding the Leak
1. Identify the fluid. Determine whether it is engine oil,
automatic transmission fluid, power steering fluid,
etc.
2. Identify where the fluid is leaking from.
2.1 After running the vehicle at normal operating
temperature, park the vehicle over a large sheet
of paper.
2.2 Wait a few minutes.
2.3 You should be able to find the approximate loca-
tion of the leak by the drippings on the paper.
3. Visually check around the suspected component.
Check around all the gasket mating surfaces for
leaks. A mirror is useful for finding leaks in areas that
are hard to reach.
4. If the leak still cannot be found, it may be necessary
to clean the suspected area with a degreaser, steam
or spray solvent.
4.1 Clean the area well.
4.2 Dry the area.
4.3 Operate the vehicle for several miles at normal
operating temperature and varying speeds.
4.4 After operating the vehicle, visually check the
suspected component.
4.5 If you still cannot locate the leak, try using the
powder or black light and dye method.
Powder Method
1. Clean the suspected area.
2. Apply an aerosol-- type powder (such as foot powder)
to the suspected area.
3. Operate the vehicle under normal operating condi-
toins.
4. Visually inspect the suspected component. You
should be able to trace the leak path over the white
powder surface to the source.
Black Light and Dye Method
A dye and light kit is available for finding leaks, Refer to
the manufacturer ’s directions when using the kit.
1. Pour the specified amount of dye into the engine oil fill
tube.
2. Operate the vehicle normal operating conditions as
directed in the kit.
3. Direct the light toward the suspected area. The dyed
fluid willappear as a yellow path leading to the
source.
Repairing the Leak
Once the origin of the leak has been pinpointed and
traced back to its source, the cause of the leak must be
determined n order for it to be repaired properly. If a gas-
ket is replaced, but the sealing flange is bent, the new
gasket will not repair the leak. Thebent flange must be
repaired also. Before attempting to repair a leak, check
for the following conditions and correct them as they
may cause a leak.
Gaskets
DThe fluid level/pressure is too high.
DThe crankcase ventilation system is malfunctioning.
DThe fasteners are tightened improperly or the threads
are dirty or damaged.
DThe flanges or the sealing surface is warped.
DThere are scratches, burrs or other damage to the
sealing surface.
DThe gasket is damaged or worn.
DThere is cracking or porosity of the component.
DAn improper seal was used (where applicable).
Seals
DThe fluid level/pressure is too high.
DThe crankcase ventilation system is malfunctioning.
DThe seal bore is damaged (scratched, burred or
nicked).
DThe seal is damaged or worn.
DImproper installation is evident.
DThere are cracks in the components.
DThe shaft surface is scratched, nicked or damaged.
DA loose or worn bearing is causing excess seal wear.

DIAGNOSIS
BASIC KNOWLEDGE REQUIRED
You must be familliar with some basic electronics to
use this section of the Service Manual. They will help
you to follow diagnostic procedures.
Notice: Lack of the basic knowledge of this transmis-
sion when performing diagnostic procedures could re-
sult in incorrect diagnostic performance or damage to
transmission components. Do not, under any circum-
stances, attempt to diagnose a transmission problem
without this basic knowledge.
Notice: If a wire is probed with a sharp instrument
and not properly sealed afterward, the wire will corrode
and an open circuit will result.
Diagnostic test probes are now available that allow
you to probe individual wires without leaving the wire
open to the environment. These probe devices are
inexpensive and easy to install, and they permanently
seal the wire from corrosion.
Special Tools
You should be able to use a Digital Volt Meter (DVM),
a circuit tester, jumper wires or leads and a line
pressure gauge set. The functional check procedure
is designed to verify the correct operation of electronic
components in the transmission. This will eliminate the
unnecessary removal of transmission components.
FUNCTIONAL CHECK
PROCEDURE
Begin with the Functional Check Procedure which pro-
vides a general outline of how to diagnose automatic
transmission. The following functional check procedure
will indicate the proper path of diagnosing the transmis-
sion by describing the basic checks and then referenc-
ing the locations of the specific checks.
Check the fluid level according to the Fluid Level
Service Procedure.
Check the transmission fluid leak.
Check if the transmission fluid is not burnt by smell.
Notice: The specific fluid used in this transmission
turns brown during normal operation. Brown fluid
does not indicate a transmission fault.
Ensure that the transmission is not in Limp Home
Mode (LHM).
Check the battery terminals and the earth connec-
tions for corrosion or looseness.
Check that the cooler flow is not restricted.
Check all electrical plug connections for tightness.
Use on-board diagnostic tool or a scan tool to see
if any transmission trouble codes have been set.
DIAGNOSTIC INFORMATION AND PROCEDURES
Refer to the appropriate “Diagnostic Trouble Code
(DTC)” information and repair the vehicle as
directed. After repairing the vehicle, perform the
road test and verify that the code has not set again.
Perform the Electrical/Garage Shift Tests.
Perform the Road Test Procedure in this section.
Inspect the oil and check for metal or other contami-
nants in the oil pan.
TRANSMISSION FLUID LEVEL
SERVICE PROCEDURE
This procedure is to be used when checking a concern
with the fluid level in a vehicle. A low fluid level will
result in slipping and loss of drive/ reverse or delay on
engagement of drive/ reverse when the vehicle is cold.
The vehicle is first checked for transmission diagnostic
messages on the scan tool. If the oil level is low, it is
possible to register a vehicle speed signal fault.
The vehicle is to be test driven to determine if there is
an abnormal delay when selecting drive or reverse, or
loss of drive. One symptom of low fluid level is a
momentary loss of drive when driving the vehicle around
a corner. Also when the transmission fluid level is low,
a loss of drive may occur when the transmission fluid
temperature is low.
If there is no loss of drive when the vehicle is driven
warm and a vehicle speed signal fault is registered,
then fluid should be added to the transmission.
When adding or changing transmission fluid use only
Castrol TQ 95 automatic transmission fluid. The use of
incorrect fluid will cause the performance and durability
of the transmission to be severely degraded.
Fluid Level Diagnosis procedure
1. If the vehicle is at operating temperature allow the
vehicle to cool down for two hours, but no greater
than four hours. Or if the vehicle is at cool status,
start the engine and allow the engine to idle for
approximately 5 minutes or, if possible, drive the
vehicle for a few kilometers. This will allow the
transmission to be within the correct temperature
range. Transmission fluid level should be checked
at temperature 50 - 60 °C (82 - 140 °F).
Caution: Removal of the fluid filler plug when
the transmission fluid is hot may cause injury if
fluid drains from the filler hole.
2. With the brake pedal pressed, move the gear shift
control lever through the gear ranges, pausing a
few seconds in each range. Return the gear shift
control lever to P (Park). Turn the engine OFF.
3. Park the vehicle on a hoist, inspection pit or similar
raised level surface. The vehicle must be control
level to obtain a correct fluid level measurement.

AUTOMATIC TRANSMISSION 5A-39
SSANGYONG MY2002
4. Place a fluid container below the fluid filler plug.
5. Clean all dirt from around the fluid filler plug.
Remove the fluid filler plug. Clean the filler plug
and check that there is no damage to the ‘O’ ring.
If fluid drains through the filler hole the transmis-
sion may have been overfilled. When the fluid
stops draining the fluid level is correct. Install
the fluid filler plug and tighten it to 33 Nm (24
lb-ft).
If fluid does not drain through the filler hole, the
transmission fluid level may be low. Install the
filler pump into the filler hole. Lower the vehicle
with the filler pump still connected and partially
fill the fluid through the filler hole.
Start the vehicle in P (Park) with the parking
brake and the brake applied. With the engine
idling, move the gear shift. control lever through
the gear ranges, pausing a few seconds in each
range and adding the fluid until gear application
is felt.
Return the gear shift lever to P (Park).
Turn the engine OFF and raise the vehicle. When
the three minutes passed after the engine
stopped, remove the filler pump.
Check if the fluid level is aligned with the bottom
of the filler hole. If not, add a small quantity of
fluid to the correct level. Install the fluid filler
plug and tighten it to 33 Nm (24 lb-ft).
If fluid does not drain through the filler hole al-
though adding a total of 1.5 liters, the transmission
should be inspected for fluid leaks and any leaks
should be fixed before setting the transmission
fluid level.
6. When the fluid level checking procedure is com-
pleted, wipe any fluid around the filler plug with a
rag or shop towel.
Fluid Level Set After Service
1. Depending on the service procedure performed,
add the following amounts of fluid through the filler
plug hole prior to adjusting the fluid level:
Converter empty 8.0 liters (8.5 quarts)
Converter full 3.8 liters (4.0 quarts)
2. Follow steps 1 through 4 of the Fluid Level Diagnosis
Procedure.
3. Clean all dirt from around the fluid filler plug.
Remove the fluid filler plug. Clean the filler plug
and check that there is no damage to the ‘O’ ring.
4. Lower the vehicle with the filler pump still connected
and start the vehicle in P (Park) with the parking
brake and the brake applied. With the engine idling,
move the gear shift control lever through the gear
ranges, pausing a few seconds in each range and
adding the fluid until gear application is felt.Then add an additional 0.5 litres of fluid. Return
the gear shift lever to P (Park). Turn the engine OFF
and raise the vehicle. Install the fluid filler plug and
tighten it to 33 Nm (24 lb-ft).
5. Drive the vehicle at 3.5 to 4.5 kilometers with light
throttle so that the engine does not exceed 2500
rpm.
This should result in the transmission temperature
being in the range 50 - 60 °C (82 - 140 °F). With the
brake applied, move the shift lever through the gear
ranges, pausing a few seconds in each range at
the engine idling.
6. Return the gear shift lever to P (Park).
Turn the en-gine OFF and raise the vehicle on the
hoist, if applicable, ensuring the vehicle is level.
When the three minutes passed after the engine
stopped, remove the filler plug.
Check if the fluid level is aligned with the bottom of
the filler hole. If not, add a small quantity of fluid to
the correct level. Install the fluid filler plug and
tighten it to 33 Nm (24 lb-ft).
7. Wipe any fluid around the filler plug with a rag or
shop towel.
FLUID LEAK DIAGNOSIS AND
REPAIR
The cause of most external leaks can generally be lo-
cated and repaired with the transmission in the vehicle.
Methods for Locating Leaks
General Method
1. Verify that the leak is transmission fluid.
2. Thoroughly clean the suspected leak area.
3. Drive the vehicle for approximately 25 km (15 miles)
or until the transmission reaches normal operating
temperature (88 °C, 190 °F).
4. Park the vehicle over clean paper or cardboard.
5. Turn the engine OFF and look for fluid spots on the
paper.
6. Make the necessary repairs to correct the leak.
Powder Method
1. Thoroughly clean the suspected leak area.
2. Apply an aerosol type powder (foot powder) to the
suspected leak area.
3. Drive the vehicle for approximately 25 km (15 miles)
or until the transmission reaches normal operating
temperature (88 °C, 190 °F).
4. Turn the engine OFF.
5. Inspect the suspected leak area and trace the leak
path through the powder to find the source of the
leak.
6. Make the necessary repairs.

SSANGYONG MY2002
Dye and Black Light Method
1. Add dye to the transmission through the transmission
fluid filler plug. Follow the manufacturer’s recommen-
dation for the amount of dye to be used.
2. Use the black light to find the fluid leak.
3. Make the necessary repairs.
Repairing the Fluid Leak
Once the leak point is found the source of the leak
must be determined. The following list describes the
potential causes for the leak:
Fasteners are not torqued to specification.
Fastener threads and fastener holes are dirty or
corroded.
Gaskets, seals or sleeves are misaligned, damaged
or worn.
Damaged, warped or scratched seal bore or gasket
surface.
Loose or worn bearing causing excess seal or sleeve
wear.
Case or component porosity.
Fluid level is too high.
Plugged vent or damaged vent tube.
Water or coolant in fluid.
Fluid drain back holes plugged.
ELECTRICAL / GARAGE SHIFT
TEST
This preliminary test should be performed before a hoist
or road test to make sure electronic control inputs are
connected and operating. If the inputs are not checked
before operating the transmission, a simple electrical
condition could be misdiagnosed as a major
transmission condition.
A scan tool provides valuable information and must
be used on the automatic transmission for accurate
diagnosis.
1. Move gear shift control lever to P (Park) and set
the parking brake.
2. Connect scan tool to Data Link Connector (DLC)
terminal.
3. Start engine.
4. Turn the scan tool ON.
5. Verify that the appropriate signals are present.
These signals may include:
ENGINE SPEED
VEHICLE SPEED

6. Monitor the A/C COMPRESSOR STATUS signal
while pushing the A/C switch.
The A/C COMPRESSOR STATUS should come
ON when the A/C switch is pressed, and turn
OFF when the A/C switch is repushed.
7. Monitor the GEAR SHIFT LEVER POSITION signal
and move the gear shift control lever through all
the ranges.
Verify that the GEAR SHIFT LEVER POSITION
value matches the gear range indicated on the
instrument panel or console.
Gear selections should be immediate and not
harsh.
8. Move gear shift control lever to neutral and monitor
the THROTTLE POSITION signal while increasing
and decreasing engine speed with the accelerator
pedal.
THROTTLE POSITION should increase with en-
gine speed.

SSANGYONG MY2002
Dye and Black Light Method
1. Add dye to the transmission through the transmission
fluid filler plug. Follow the manufacturer’s recommen-
dation for the amount of dye to be used.
2. Use the black light to find the fluid leak.
3. Make the necessary repairs.
Repairing the Fluid Leak
Once the leak point is found the source of the leak
must be determined. The following list describes the
potential causes for the leak:
Fasteners are not torqued to specification.
Fastener threads and fastener holes are dirty or
corroded.
Gaskets, seals or sleeves are misaligned, damaged
or worn.
Damaged, warped or scratched seal bore or gasket
surface.
Loose or worn bearing causing excess seal or sleeve
wear.
Case or component porosity.
Fluid level is too high.
Plugged vent or damaged vent tube.
Water or coolant in fluid.
Fluid drain back holes plugged.
ELECTRICAL / GARAGE SHIFT
TEST
This preliminary test should be performed before a hoist
or road test to make sure electronic control inputs are
connected and operating. If the inputs are not checked
before operating the transmission, a simple electrical
condition could be misdiagnosed as a major
transmission condition.
A scan tool provides valuable information and must
be used on the automatic transmission for accurate
diagnosis.
1. Move gear shift control lever to P (Park) and set
the parking brake.
2. Connect scan tool to Data Link Connector (DLC)
terminal.
3. Start engine.
4. Turn the scan tool ON.
5. Verify that the appropriate signals are present.
These signals may include:
ENGINE SPEED
VEHICLE SPEED
THROTTLE POSITION
ACCEL. PEDAL POSITION
TRANSMISSION GEAR STATE
GEAR SHIFT LEVER POSITION
TRANSMISSION FLUID TEMPERATURE
CLOSED THROTTLE POSITION LEARN
OPEN THROTTLE POSITION LEARNT
CLOSED ACCEL. PEDAL POSITION LEARNT

6. Monitor the A/C COMPRESSOR STATUS signal
while pushing the A/C switch.
The A/C COMPRESSOR STATUS should come
ON when the A/C switch is pressed, and turn
OFF when the A/C switch is repushed.
7. Monitor the GEAR SHIFT LEVER POSITION signal
and move the gear shift control lever through all
the ranges.
Verify that the GEAR SHIFT LEVER POSITION
value matches the gear range indicated on the
instrument panel or console.
Gear selections should be immediate and not
harsh.
8. Move gear shift control lever to neutral and monitor
the THROTTLE POSITION signal while increasing
and decreasing engine speed with the accelerator
pedal.
THROTTLE POSITION should increase with en-
gine speed.
