PURPOSE
Procedures are now available for W6DGA TC−SST clutch assembly replacement. This TSB provides the
necessary steps to complete diagnosis, clutch assembly replacement, and complete “teach−in” for the
TCM.
This TSB is used together with the service manual, TSB−13−22−001: TC−SST Transmission and
Mechatronic Assembly Diagnosis and Repair, and TSB−13−22−003: TC−SST Diagnosis and Overhaul
− Service Manual Revision, to provide procedures for the complete and accurate diagnosis and repair of
the TC−SST transmission. These procedures will eliminate the need to replace TC−SST transmissions
to address the most common symptoms.
This TSB covers the following subjects:
1. Remove and replace the clutch assembly.
2. Complete those “teach−in” procedures necessary after clutch replacement.
NOTE: 2008 Lancer Evolution and early production 2009 Lancer and Lancer Sportback Ralliart (software
Version 0000) require additional reprogramming steps, which are covered in the repair procedure.
Also included are:
1. A Customer Interview Worksheet to be used by dealer service personnel to help identify specific
transmission concerns.
2. A diagnosis and repair overview.
3. Diagnostic steps required prior to clutch assembly replacement.
4. Instructions for conducting “Teach−In” procedures after installing the new clutch assembly.
5. A Quality Control Checklist to verify proper repair.
6. Part number information.
Diagnosis and repairs for symptoms not covered by the service manual, this TSB, TSB 13−22−001 or
TSB−13−22−003 may require transmission replacement.

AFFECTED VEHICLES
2008 – 2013 Lancer Evolution with TC−SST
2009 – 2013 Lancer Ralliart Edition with TC−SST
2009 – 2011 Lancer Sportback Ralliart Edition with TC−SST

TC−SST CLUTCH ASSEMBLY REPLACEMENT OVERVIEW
Clutch assembly replacement requires transmission removal and uses specific special tools. It also
requires a “Teach−in” procedure to program the transmission control module with the parameters of the
new clutch assembly. If “teach in” is not completed, shifting may be unstable (harsh shifts, slipping, etc.)
Clutch “teach−in” uses some of the “teach−in” procedures for the Mechatronic Assembly (see
TSB−13−22−001). Additional required steps have been added for clutch assembly replacement.

After completing service manual diagnostic steps, you may be instructed to replace the clutch assembly.
If this does not correct the observed symptoms, transmission replacement may be required. Complete
transmission assembly replacement may require prior approval. Contact your District Parts and Service
Manager prior to replacing the transmission.
Repairs to the TC−SST are limited to the following:
D

Mechatronic assembly replacement and programming

D

Clutch Assembly Replacement

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

DIAGNOSTIC OVERVIEW
The following diagnostic overview highlights diagnostic steps to be followed. Do not perform diagnosis
and repair using this overview alone. Use the steps described later in this TSB, TSB−13−00−003 or the
service manual.
1. Using the Customer Interview Worksheet included in this TSB will help you understand the specific
transmission related symptoms experienced by the customer. The worksheet can also be
downloaded from the “service tech resources” page of the MDL.
2. Perform a thorough visual inspection and check the basics.
D

Note any transmission related MID display messages.

D

Check transmission fluid level and condition. Refer to the service manual for the proper
procedure.

D

Check Battery voltage (> 12.4V as measured at the battery).

D

Verify no electrical or performance accessories are installed.

D

Verify integrity of transmission electrical harness and associated connectors.

3. Connect MUT−III to the vehicle.
NOTE: If engine ECU or TCM tampering is suspected, contact your DPSM and Techline with the details.
D

Perform CAN bus check.

D

Record DTCs and Freeze Frame Data. Then perform Erase and Read DTCs.

4. Road test the vehicle to verify the concern and duplicate any previously retrieved DTCs.
5. Replace the clutch assembly (if diagnosis leads you in this direction).
If replacing the clutch assembly on 2008 Lancer Evolution and early 2009 Lancer or Lancer Sportback
Ralliart vehicles (software version 0000 only), you must reprogram the TCM to a later model version
before “teach−in” can be completed. After completing “teach−in”, you will reprogram the TCM back
to version 0000.
6. Perform clutch “teach−in.”
7. Road test the vehicle to verify repair.
8. Complete the Quality Control Checklist.

Perform the ACTION TO TAKE after each DIAGNOSTIC STEP listed below:
DIAGNOSTIC STEP
DIAG1)
Are there any transmission related
messages displayed? (Yes or No)

ACTION TO TAKE
MID

Note any messages and continue diagnosis at
DIAG2.
A. If the Service Required message is displayed,
check for DTCs.
B. If the Slow Down message is displayed, the
transmission is overheating. Ask the customer
if they have noticed this message displayed.
The SLOW DOWN message displays if
transmission temperature exceeds 250oF. If
the transmission temperature exceeds 260oF,
the ECU and TCM will take steps to cool down
the transmission including reducing power and
disengaging the clutches.

DIAG2)
Is there any aftermarket equipment (engine or
transmission performance equipment, navigation
units, gauges, tracking devices, etc.) installed on
this vehicle? (Yes or No)
Pay special attention to those devices which can
be linked to the vehicle communications networks
(CAN B, CAN C, or LIN).

If aftermarket equipment is found, disconnect it or
render it inoperative for the remainder of this
diagnosis. Go to DIAG3.

DIAG3)
Are there any transmission fluid leaks? (Yes or
No)

Note the location(s) of any leaks and continue
diagnosis at DIAG4.

DIAG 4)
Is the valve body electrical harness connector
fully seated? (Yes or No)

If no, secure the connector. After preparing the
scan tool as shown on page 7, continue to DIAG5.

DIAG5)
Perform CAN Bus Diagnosis to confirm proper
network communication. If necessary, consult
GROUP 54C of the Service Manual for the
procedure.

Follow Service Manual procedures (GROUP
54C) for any ECUs failing CAN Bus diagnosis.
After diagnosis and repair of CAN Bus, continue
diagnosis at Step DIAG6.
If CAN Bus diagnosis passed, continue diagnosis
at Step DIAG6.
