PURPOSE
Procedures are now available for W6DGA TC−SST Mechatronic Assembly (valve body and transmission
control module) replacement. This TSB provides the necessary steps to complete diagnosis, replace the
Mechatronic Assembly, and program the new electronic control unit.
Until now, authorized repairs for the TC−SST were limited to replacement of axle seals, transmission oil
pan and gasket, and the external oil filter. With the addition of Mechatronic Assembly replacement,
dealers no longer have to replace the transmission assembly to address the most common TC−SST
symptoms.
This TSB covers the following subjects:
1. An overview of the TC−SST operation (page 2).
2. Diagrams of the transmission showing selected replacement parts (page 4).
3. A Customer Interview Worksheet to be used by dealer service personnel to identify specific
transmission concerns (page 6).
!! IMPORTANT !! You are required to submit a completed customer interview sheet to Techline
for parts release.
4. Transmission troubleshooting instructions (page 7).
5. Mechatronic assembly replacement instructions including TCM programming (page 14).
6. A Quality Control Checklist to verify proper repair (page 41).
7. Part number information (page 42).
Diagnosis and repairs for DTCs and other symptoms not covered by this TSB may require transmission
replacement. For TC−SST diagnosis and repairs not covered by this TSB, contact Techline for assistance.
NOTE: Unlike most Mitsubishi electronic control units, a new Mechatronic assembly’s TCM is not
programmed with operating software. When a new Mechatronic assembly is installed, the
technician must program it following the steps provided in this TSB.
Repairs to the TC−SST are limited to the following:
D
Mechatronic assembly replacement and programming
D
Teach−in procedure for all model years (2008 Lancer Evolution is unique)
D
External oil filter/housing replacement
D
Axle seal replacement
D
Oil pan and pan seal replacement

TC−SST OPERATION OVERVIEW
The Mitsubishi TC−SST is an automated, 6−speed manual transmission. It contains the mechanical
gearing, hydraulic control (valve body) and the transmission control module (TCM). The valve body and
TCM are known as the Mechatronic Assembly. They are permanently attached to each other and cannot
be replaced separately.
The TC−SST distributes power in a manner similar to any other manual transmission. It uses gears with
brass synchronizers controlled by shift rails and forks to transmit power to the drive wheels. However, the
TC−SST uses two gear shafts; one for odd numbered gears and one for even numbered gears. The
automated portion of the transmission incorporates hydraulic servos to move the shift forks that engage
the gears, magnetic sensors to inform the TCM of shift fork positioning, other sensors to monitor clutch
pack speed, a valve body to direct hydraulic oil flow to appropriate points, and wet clutches (one per shaft)
to engage or disengage the odd or even gear shaft at the correct time.
The wet clutch system performs a similar function to a torque convertor in an automatic transmission. The
clutches are fully disengaged to allow the vehicle to idle, or engaged one at a time, allowing engine torque
to be transmitted through the gears on either the odd or even gear shaft.
The advantages of using the twin clutch setup are:
D increased shift speed
D reduced torque loss during shifts
D improved fuel economy
Shift Pattern
The driver can select either “Automatic Mode” or “Manual Mode” using the shift lever.
Automatic Mode
Shift knob
Manual Mode
Shift Lever Position
In automatic mode, the transmission shifts gears based
on shift mapping programmed into the transmission
control module, similar to a conventional automatic
transmission. In the manual mode, sequential gear
shifting is performed using either the floor shifter (+ for
upshifts, — for downshifts), or the steering column
mounted paddle shifters (right hand for upshifts, left hand
for downshifts).
Paddle Shift Operated

Shifting gears switches to manual mode.
NOTE: Returns to automatic mode when
vehicle speed drops to 6.25 mph (10 km/h).
If the right hand shift paddle is pulled and held
for more than 2 seconds, manual mode is cancelled.
Manual Shift Gate (+/—)
No/Yes
Manual mode
NOTE: In manual mode, as the vehicle slows,
the TCM automatically commands downshifts
to select a gear appropriate to vehicle speed.

Drive Mode
Ralliart models have two drive modes: Normal and Sport.
Lancer Evolution models have three drive modes: Normal,
Sport and Super Sport.
When the engine is started, the drive mode defaults to
Normal.
TC−SST Control
Mode Switch
Each drive mode has a specific shift “feel.” The softest shift
feel occurs in the default Normal mode. In Sport mode,
shifts are quicker and occur at higher RPM. In Super Sport
mode, shifting is the most aggressive. Shifts occur at even
higher engine speeds and even more quickly than Sport
mode. (Super Sport is not recommended for normal street
use as shifting is very harsh).

Creep Function
The TCM is programmed to slip the clutches in both D and R ranges (a semi−engaged state) to enable
a creep drive condition similar to that provided by an automatic transmission torque convertor.
Kick Down Function
A kick down function (similar to an automatic transmission) is programmed into the TCM and allows
automatic downshifts when the accelerator pedal is fully depressed, providing quicker acceleration.
Page 4 of 42
TSB−13−22−001
Fast Off Function
Under normal circumstances, with the transmission in D range, when the accelerator pedal is suddenly
released, the transmission upshifts to better suit vehicle speed. However, under certain parameters, a
“fast off” function prevents upshifts in order to achieve engine braking.
Network Communication

The TC−SST, like most of the vehicle’s major
components, is constantly communicating with other
control units linked via the CAN C bus line. When
diagnosing electrical issues, it is important to focus on
proper electrical connections and communication. It also
means that, similar to the vehicle’s other control units,
MUT−III must be used to program the TCM after
replacement. Part of this TSB will focus on procedures
for proper coding when replacing Mechatronic
assemblies.
