AUTOMATIC TRANSMISSION 5A-3
SSANGYONG MY2002
N - Neutral allows the engine to be started and oper-
ated while driving the vehicle. The inhibitor switch
allows the engine to be started. There is no power
transferred through the transmission in Neutral. But
the final drive is not locked by the parking pawl, so
thewheels are free to rotate.
D - Overdrive range is used for all normal driving
conditions. 4th gear (overdrive gear) reduces the
fuel consumption and the engine noise. Engine
braking is applied with reduced throttle.
First to second (1 → 2), first to third (1 → 3), second
to third (2 → 3), second to fourth (2 → 4), third to
fourth (3 → 4), fourth to third (4 → 3), fourth to
second (4 → 2), third to second (3 → 2), third to
first (3 → 1) and second to first (2 → 1) shifts are
all available as a function of vehicle speed, throttle
position and the time change rate of the throttle
position.
Downshifts are available for safe passing by
depress-ing the accelerator. Lockup clutch may be
enabled in 3rd and 4th gears depending on vehicle
type.
3 - Manual 3 provides three gear ratios (first through
third) and prevents the transmission from operating
in 4th gear. 3rd gear is used when driving on long
hill roads or in heavy city traffic. Downshifts are
available by depressing the accelerator.
2 - Manual 2 provides two gear ratios (first and
second). It is used to provide more power when
climbing hills or engine braking when driving down
a steep hill or starting off on slippery roads.
1 - Manual 1 is used to provide the maximum engine
braking when driving down the severe gradients.When NORMAL mode is selected upshifts will occur
to maximize fuel economy. When POWER mode is se-
lected, upshifts will occur to give maximum
performance and the POWER mode indicator light is
switched ON.
When WINTER mode is selected, starting in second
gear is facilitated, the WINTER mode indicator light is
switched ON and the POWER mode indicator light is
switched OFF.
Indicator Light
The indicator light is located on the instrument panel.
Auto shift indicator light comes ON when the ignition
switch ON and shows the gear shift control lever
position.
POWER mode indicator light comes ON when the
POWER mode is selected and when the kickdown
switch is depressed.
WINTER mode indicator light comes ON when the
WINTER mode is selected.
CONTROL SYSTEMS
BTRA M74 4WD automatic transmission consists of
two control systems. One is the electronic control
system that monitors vehicle parameters and adjusts
the transmission performance. Another is the hydraulic
control system that implements the commands of the
electronic control system commands.
ELECTRONIC CONTROL SYSTEM
The electronic control system comprises of sensors, a
TCM and seven solenoids. The TCM reads the inputs
and activates the outputs according to values stored
in Read Only Memory (ROM).
The TCM controls the hydraulic control system. This
control is via the hydraulic valve body, which contains
seven electromagnetic solenoids. Six of the seven
solenoids are used to control the line pressure, operate
the shift valves and the torque converter lock-up clutch,
and to turn ON and OFF the two regulator valves that
control the shift feel.
The seventh solenoid is the proportional or Variable
Pressure Solenoid (VPS) which works with the two regu-
lator valves to control shift feel.
Transmission Control Module (TCM)
The TCM is an in-vehicle micro-processor based trans-
mission management system. It is mounted under the
driver’s side front seat in the vehicle cabin.
The TCM contains:
Processing logic circuits which include a central mi-
croprocessor controller and a back-up memory
system.
Input circuits.
Driving Mode Selector
The driving mode selector consists of a driving mode
selector switch and indicator light. The driving mode
selector is located on the center console and allows
the driver to select the driving mode.
The driving modes available to be selected vary with
vehicle types. Typically the driver should have the
option to select among NORMAL, POWER and
WINTER modes.

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.
