Rear axle assembly
The rear axle installed in this car is a removable
axle, called IRDA (Independent Rear Differential
Axle). The rear differential carrier is installed
directly on the sub frame, and there is an
independent suspension that allows each wheel
on the same axle to move vertically independentl

joint.
E-coupling control unit (E-Coupling ECU)
The E-coupling unit is a control unit which determines

3) General Instructions
Before lifting up the vehicle with a lift, correctly support the lifting points.
When using a jack, park the vehicle on a level ground and place the wheel chocks under the tires.
Position the jack under the frame and lift up the vehicle and then support with chassis stand before
service work.
Make sure to disconnect the negative (-) cable from the battery to prevent any damage to electric
systems.
If you have to work on vehicle, cover the seats and floor with protection covers to avoid any
damage and contamination.
Brake fluid and anti-freeze can damage the painted surface of body. So carefully handle them
during service work.
To improve the efficiency of service work, use only recommended and specified tools.
Use only Ssangyong genuine spare parts.
Never reuse the cotter pin, gasket, O-ring, oil seal, lock washer and self-locking nut. Replace them
with new ones. If reused, normal functions cannot be maintained.
Store the disassembled parts as a set based on disassembly order and unit.
Pay particular attention not to miss or mix the fasteners.
If necessary, especially for inspection, clean the removed parts completely.
Apply the oil or grease on the running and sliding surfeces before installation. Use the specified
sealant and gasket to prevent leakage if necessary.
Tighten the fasteners to the specified tightening torque.
As a final stage of service work, check if the serviced system is working properly and the problem
has been eliminated clearly. (1)

1. OVERVIEW
Engine power reaches the transaxle via a torque converter with integral converter lock-up clutch. The six
forward gears and one reverse gear are obtained from a single planetary set, followed by a double
planetary set. This type of gear-set arrangement is commonly known as Lepelletier type gear-set.
The Model M11 6 speed automatic transaxle is electronically controlled. The control system is
comprised of the following components:
External transaxle control unit (TCU)
Internal embedded memory module (EMM)
Input and output speed sensors
Valve body unit comprised of four ON/OFF solenoid valves and six variable bleed solenoids (VBS)
Torque converter -

TCU controls the oil pressure for various internal clutches and bands to select the gear. It also controls
the electronic elements, shift pressure and torque converter slip. If the system is defective, TCU provides
FMEC (Failure Mode Effect Control) to maintain the functionality of transaxle. This keeps the basic
function of transaxle (gear selection) even when there are failure in controls and power supply.
There are selector shaft position sensor (inhibitor switch) and oil temperature sensor in transaxle. In
manual mode, TCU receives the information from TGS (Transmission Gear Selector) through PCB
(Printed Circuit Board) when driver selects the manual shift mode. TCU communicates with other
electric control modules through CAN. In order to ensure a safe driving state and to prevent damage to
the automatic transmission, TCU switches to Limp-Home mode in the event of critical faults.

2) Transaxle Cooling
The transaxle cooling system ensures rapid warm-up and constant operating temperature resulting in
reduced fuel consumption and refined shift quality.
It also includes a cooler by-pass within the hydraulic system to allow sufficient lubrication to the transaxle
drivetrain in the event of a blockage in the transaxle cooler.
3) Shift Strategy
Gear Change ▶
Transaxle gear change is controlled by the
TCU. The TCU receives inputs from various
engine and vehicle sensors to select shift
schedules and to control the shift feel and
torque converter clutch (TCC) operation at each
gear change.
Coast down ▶
Coast down down shifts occur at 0% pedal
when the vehicle is coasting down to a stop.
Torque Demand ▶
Torque demand down shifts occur
(automatically) when the driver demand for
torque is greater than the engine can provide at
that gear ratio. If applied, the transaxle will
disengage the TCC to provide added
acceleration.

4. LIMP HOME MODE
When the transaxle is defective ▶
In the event of a system fault, the TCU also provides for failure mode effect control (FMEC) to maintain
maximum functional operation of the transaxle.
In the event of a total loss of control or electrical power, the basic transaxle functions (Park, Reverse,
Neutral and Drive) are retained. The 4th and reverse gear ratios with the torque converter clutch in the
unlocked state are the retained gear states the hydraulic system supports without any electrical
assistance.
The TCU communicates with other vehicle electronic control modules by the controller area network
(CAN). If a major fault develops, the transaxle may automatically operate in a "limp home" (failure)
mode to enable the vehicle to be driven to an authorized dealer for repair.
The TCU also provides for transaxle diagnostics, which meet the requirements of OBD II legislation,
monitoring all components which may effect vehicle emissions. 1.

When the transaxle overheats ▶
Limp home mode may also be engaged if the battery charge falls below 8V.
If the transaxle overheats, the shift patterns will automatically change to enable improved transaxle
cooling.

Towing the automatic transaxle equipped vehicle ▶
Flat-bed equipment is the best method of moving a disabled vehicle to avoid any damages.
For AWD vehicle: The vehicle must be towed with a wheel lift and dollies or flatbed equipment with
all the wheels off the ground.
For 2WD vehicles: It is acceptable to tow the vehicle with the rear wheels on the ground without
dollies and the front wheels off the ground. When being towed by a commercial towtruck and wheel
dollies are not available, the front of the vehicle should be lifted, not the rear. -
