This bulletin supersedes TSB-20-23-002REV3, issued March 2024 to update Affected Vehicles and add warranty
labor operation information for CVT replacement. 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.
Please refer to the Service Manual Revision found in TSB-24-23-001 regarding the Procedure for
Diagnostic Trouble Code and On-Vehicle Service for Belt & Pulley Assembly on CVT F1CJC and
W1CJC, as needed.
AFFECTED VEHICLES
* 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.
