SUBJECT: No: POTENTIAL TRANSMISSION SHUDDER/SURGE DATE: WITH POSSIBLE DTC (CVT-8) - REVISED MODEL: TSB-20-23-001REV3 March 2024 See below CIRCULATE TO: [ ] GENERAL MANAGER [ X ] PARTS MANAGER [ X ] TECHNICIAN [ X ] SERVICE ADVISOR [ X ] SERVICE MANAGER [ X ] WARRANTY PROCESSOR [ ] SALES MANAGER This bulletin supersedes TSB-20-23-002REV2, issued February 2022, to add additional inspection, determination, repair procedures, parts and warranty information. Revisions are italicized and indicated by " PURPOSE Certain vehicles with F1CJC/W1CJC (CVT-8) transmissions may exhibit a shudder or surge condition possibly caused by poor reaction of the hydraulic pressure circuit. With continued driving under these conditions, the CVT belt may slip repeatedly when accelerating, and abrasion powder may enter the hydraulic pressure circuit, causing a warning light to turn on with one of the following DTCs: P0776, P0730, P0741, P084A, P0969, P2719. The shudder/ surge condition may also be described as engine flare, lack of acceleration, and/or car shake. This TSB instructs dealers to diagnose and test drive vehicles exhibiting this condition. For all vehicles, verify that SR-16-006 has been completed for vehicles listed in that Recall bulletin (2016 Lancer, 2016 Outlander, and 2015-2016 Outlander Sport: CVT ECU should be updated to the software numbers listed in the “CVT ECU Reprogramming Chart” in this TSB, or higher). If any of the DTCs previously listed are present, dealers are required to submit data from MUTIII-SE, create a Techline case, follow inspection procedures related to recorded DTCs, and make necessary repair based on results. A replacement transmission should ONLY be ordered if approved by Techline or your DPSM. AFFECTED VEHICLES The following vehicles equipped with F1CJC/W1CJC (CVT-8) transmissions ONLY: D 2018 - 2020 / 2022-2024 Eclipse Cross* D 2016 - 2017 Lancer with 2.0L/2.4L engine D 2016 - 2020 Outlander with 2.4L engine* D 2022 - 2024 Outlander with 2.5L engine* D 2015 - 2024 Outlander Sport/RVR with 2.0L engine* D 2018 - 2024 Outlander Sport/RVR with 2.4L engine* * This TSB may also apply to later model years with F1CJC/W1CJC/F1CJD/W1CJD (CVT-8) transmissions (excludes any Outlander Plug-in Hybrid). NOTE: This TSB should be performed on a customer complaint basis only. Copyright 2024 Mitsubishi Motors North America, Inc. The information contained in this bulletin is subject to change.
