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.

Circuit Description
The driving mode selector switch is located on the
center console and allows the driver to select the
driving mode.
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.
The DTC P0790 sets when an intermittent connection
in the mode selector switch (mode switch) circuit has
been detected. The mode switch input is rapidly
changing states. The switching frequency is greater
than 8.3 Hz.
Conditions for Setting the DTC
The mode switching frequency is greater than 8.3
Hz.
The above condition must be continuously present
for 4 state changes.
Action Taken When the DTC Sets
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 the changes
in switch setting.
DIAGNOSTIC TROUBLE CODE (DTC) P0790
NORMAL/PERFORMANCE SWITCH CIRCUIT MALFUNCTION
Conditions for Clearing the DTC
The DTC will clear after 3 seconds without the fault.
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
This fault is caused by too many changes in the
mode input signal over a period of time.
Typical causes would be an intermittent connection
in the switch or wiring or an intermittent short to
ground in the wiring.

FRAME AND UNDERBODY 9N-7
SSANGYONG MY2002
ON-VEHICLE SERVICE
ALIGNMENT CHECKING
An accurate method of determining the alignment of
the underbody uses a measuring tram gauge. The tram
gauge set used to perform the recommended
measuring checks must include a vertical pointer able
to reach 457 mm (18 inches).
Two types of measurements can be made with a tram
gauge: direct point-to-point measurements and
measurements calculated on a horizontal plane (datum
line) parallel to the underbody. Point-to-point
measurements are generally taken on steering and
suspension engine compartment parts and simply
require the vertical pointers to be set equally.
For horizontal plane measurements, the vertical pointers
must be set as specified for each point to be measured.
Dimensions-to-gauge holes are measured to the center
of the holes and flush to the adjacent surface metal
unless otherwise specified. It is recommended that
the diagonal dimensions to the cross-body be checked
on both sides in order to verify the dimensional
accuracy of the vehicle underbody.
FLOOR PAN INSULATORS
The floor pan insulators have been designed for the
higher floor pan temperatures that result from the use
of the catalytic converter in the exhaust system.
Therefore, when servicing a vehicle, it is essential that
any insulators that may have been disturbed or removed
be reinstalled in the original sequence and location.
Also, if an insulator needs to be replaced, use only
the insula-tion specified for that location on the floor
pan.
When servicing or replacing interior insulators, observe
the following instructions.
•Install the insulators in the original position and
sequence. Butt the pieces together in order to
avoid gapping or overlapping.
If it is necessary to replace an insulator, use only
the specified insulation.
Use the original part to determine the amount of
re-placement material required and as a template
for cutting and fitting the new piece to the floor
pan.
When installing the insulator, do not enlarge any
cut-outs or holes that are used for the attachment
of interior parts such as the instrument panel or
the floor console.
