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.

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.

occurred for 3 seconds.
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
The voltage measured by the TCM across the TR
sensor input terminals has been below on
acceptable level for a significant length of time.
This would typically be caused by a short to ground
in the wiring to, or within, the inhibitor switch which
has caused the signal at the TCM to read about 0
V.
Inspect the wiring for poor electrical connections
at the TCM and at the TR sensor connector. Look
for possible bent, deformed or damaged terminals.
Also, check for chafed wires that could short to bare
metal or other wiring.
In searching for a possible intermittent short or open
condition, move or massage the wiring harness
while observing the test equipment for a change.

5A-62 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The Transmission Fluid Temperature (TFT) sensor is a
thermistor located in the solenoid wiring loom within
the valve body of the transmission. This sensor is a
typical Negative Temperature Coefficient (NTC) resistor
with low temperatures producing a high resistance and
high temperatures producing a low resistance.
If the transmission fluid temperature exceeds 135 °C
(275 °F), the TCM will impose converter lock-up at lower
vehicle speeds. Favour a lower gear to increase engine
speed, and in some vehicles flashes the mode indicator
lamp. This results in maximum oil flow through the exter-
nal oil cooler and eliminates slippage in the torque
converter. Both these actions combine to reduce the
oil temperature in the transmission.
The DTC P0710 sets when the TFT sensor signal is not
feasible.
Conditions for Setting the DTC
Transmission fluid temperature sensor signal is
greater than 4.88 volts (immediate detection).
Transmission fluid temperature sensor signal is less
than 0.21 volts (immediate detection).
Transmission temperature has not changed by 2 °C
in 15 minutes since ignition on and temperature is
less than 20 °C or greater than 125 °C.
Action Taken When the DTC Sets
Transmission fluid temperature is assumed to be
120 °C (248 °F).
All shifts will be firm until the transmission has
warmed up because a high transmission fluid
temperature is assumed.
