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

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.
ROAD TEST PROCEDURE
Perform the road test using a scan tool.
This test should be performed when traffic and road
conditions permit.
Observe all traffic regulations.
ELECTRONIC ADJUSTMENTS
Idle Speed Adjustments
Carry out the adjustments to the idle speed as detailed
in the workshop manual.
Vehicle Coding
The vehicle coding is integrated as part of the
diagnostic software. A scan tool has the function to
code the ve-hicle through the K-line.

TROUBLE CODE DIAGNOSIS - GASOLINE VEHICLE
TCM DIAGNOSTIC SYSTEM
OVERVIEW
Notice: To prevent Transmission Control Module (TCM)
damage. The ignition key must be OFF when
disconnection or reconnection the power to the TCM
(for example bttery cable, TCM pigtail connector, TCM
fuse, jumper cables, etc.).
When the TCM detects a system fault, a Diagnostic
Trouble Code (DTC) is set in the TCM. This code is
present while the fault conditions are met and is stored
as a ‘History DTC’ until cleared. Condition for setting
and clearing each TCM DTC are provided in the relevant
sections.
In the case where the vehicle type is certified for Eure
On-Board Diagnostic (EOBD) compliance, the Engine
Control Module (ECM) provides the communication linkto the EOBD scan tool to pass on any EOBD relevant
codes from the TCM. The table below contains a list of
all supported DTCs and the classification of each for
EOBD purposes. Where a type B DTC has been set in
an EOBD vehicle, the response to the fault may include
action by the ECM, including the illumination of the
Malfunction lndicator Lamp (MIL). Refer to Section 1F,
Engine Control, for details on EOBD system function,
checks and fault clearing.
CLEARING TROUBLE CODES
TCM DTCs should be cleared after repairs have been
completed. Some diagnostic tables will tell you to clear
the codes before using the chart, which will help to
find the cause of the problem more quickly. Always
note the DTCs present before clearing - this information
may be helpful in the diagnostic process.”

Circuit Description
The Transmission Control Module (TCM) Diagnistic
System Check is the starting point for any driveability
complaint diagnosis. Before using this procedure,
perform a careful visual/physical check of the
Transmission Control Module (TCM) and the
transmission grounds for cleanliness and tightness.
The TCM Diagnostic System Check is an organized
approach to identifying a problem created by an
electronic transmission control system malfunction.
TCM DIAGNOSTIC SYSTEM CHECK
Diagnostic Aids
An intermittent fault may be caused by a poor connec-
tion, rubbed-through wire insulation or a wire broken
inside the insulation. Check for poor connections or a
damaged harness. Inspect the TCM harness and con-
nections for improper mating, broken locks, improperly
formed or damaged terminals, poor terminal-to-wire
connection, and damaged harness.

5A-54 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The Transmission Range (TR) sensor is incorporated
in the inhibitor switch mounted on the side of the
transmission case. The TR sensor Indicates to the TCM
which gear position has been selected by way of a
varying resistance.
The TR sensor signal has discrete values indicating
the positions selected by the gear shift control lever
(PRND321). The Transmission Control Module (TCM)
receives that signal with a voltage varying from 0 V to
5 V. DTC P0706 sets when the TR sensor signal is not
feasi ble.
Conditions for Setting the DTC
•The engine temperature is greater than 60 °C (140 °F).
The engine speed is greater than 2000 RPM and
less than 4000 RPM.
Engine load is greater than 60 %.
DTCs P0707, P0708, P1703 and P1719 are not set.
Transmission temperature is greater than 0 °C (32 °F)
or if P0710 is present the engine coolant
temperature is greater than 60 °C (140 °F).
The TR sensor indicates that the transmission is in
a neutral state, however the engine output torque
indicates that a drive gear load is present. This
condition must be continuously present for 5
seconds.
DIAGNOSTIC TROUBLE CODE (DTC) P0706
TRANSMISSION RANGE SENSOR CIRCUIT RANGE/PERFORMANCE
Action Taken When the DTC Sets
The Malfunction Indicator Lamp (MIL) will illuminate
on the second consecutive driving cycle with the
DTC present.
The EOBD system will record operating conditions
at the time the diagnostic fails. This information will
be stored in the Failure Records buffer.
TR signal is assumed to be in the Drive position.
The transmission is limited to 2nd and R gears only.
Namely 1st, 3rd and 4th gears are inhibited.
Torque Converter Clutch (TCC) is disabled.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not oc-
curred for 30 seconds and TR is in P, R, N or D.
A history DTC will clear after 40 TCM power-up
cycles with a warm transmission (>50 °C) and
without a fault.
History DTCs can be cleared by using a scan tool.
Diagnostic Aids
Inspect the wiring for poor electrical connections
at the TCM and at the TR sensor connector. Look
for possible bent, backed out, deformed or damaged
ter-minals. Check for weak terminal tension as well.
Also, check for chafed wires that could short to bare
metal or other wiring. Inspect for broken wires inside
the in-sulation.
