MODEL: See below
SUBJECT:
TC-SST TRANSMISSION CLUTCH ASSEMBLY REPLACEMENT PROCEDURES
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:
3. A clutch assembly diagnosis and repair overview.
1. A Customer Interview Worksheet to be used by dealer service personnel to help identify specific transmission concerns.
2. Diagnostic steps required prior to clutch assembly replacement.
3. Instructions for conducting "Teach-In" procedures after installing the new clutch assembly.
4. A Quality Control Checklist to verify proper repair.
5. 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:
^ Mechatronic assembly replacement and programming
^ Clutch Assembly Replacement
^ Teach-in procedure for all model years (2008 Lancer Evolution is unique)
^ External oil filter/housing replacement
^ Axle seal replacement
^ 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.
^ Note any transmission related MID display messages.
^ Check transmission fluid level and condition. Refer to the service manual for the proper procedure.
^ Check Battery voltage (> 12.4V as measured at the battery).
^ Verify no electrical or performance accessories are installed.
^ 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.
^ Perform CAN bus check.
^ 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:
If your diagnosis results in transmission replacement, perform the following:
^ Perform "Copy Coding" to MUT-III before replacing the transmission
^ Replace the transmission assembly if necessary.
^ Perform VIN write.
^ Perform "Copy Coding" to TCM.
^ Road test to confirm repair with QC Worksheet.
