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. FEATURES
1) Advantages
Early Downshift with Hard Braking and Skip Shifts ▶
When heavy braking is detected, the transaxle downshifts early and skips gears to provide increased
engine braking to provide gear selection for tip-in.
Gear Hold going Uphill/Downhill ▶
If the accelerator pedal is released when traveling uphill, upshifts are prevented to reduce busyness on
grades. If the accelerator pedal is released when traveling downhill, upshifts are prevented to enhance
engine braking.
Drive and Reverse Engagement ▶
A soft engagement feature avoids harsh take up of drive when selecting Drive or Reverse. This is
achieved by limiting engine speed and engine torque which results in a rapid, but progressive
engagement of either Drive or Reverse when moving from the Park or Neutral positions. Drive and
Reverse engagements from either Park or Neutral are performed in less than 2.2 seconds. There is no
drive engagement prevention strategy implemented on the transaxle system as there is sufficient engine
strategy to protect the system. However, reverse engagement is prevented until engine speed is less
than 1,400 rpm and the accelerator pedal position is less than 12% and vehicle speed is less than 10
km/h.
Converter Clutch Lock-Up In All Gears ▶
The transaxle features converter clutch lock-up in all gears. This feature provides improved fuel economy
and vehicle performance. It also improves transaxle cooling efficiency when towing heavy loads at low
speeds, e.g. in city driving or hill terrain.
Embedded Memory Module (EMM) ▶
The embedded memory module (EMM) is
matched to the transaxle’s valve bodies during
transaxle assembly to ensure refined shift quality.
The EMM is used to store data such as valve body
calibration data and valve body serial number.
Upon installation, the TCU will download the data
from the EMM and utilize this data in the operation
of the transaxle.

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. -
