Summary
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. This TSB instructs dealers to diagnose and test drive vehicles exhibiting this condition. *This TSB may also apply to later model years with F1CJC/W1CJC (CVT-8) transmissions.

This bulletin supersedes TSB-17-23-002, issued April, 2017, to add more models and model years, and
additional inspection and repair procedures. Revisions are italicized and indicated by A.
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.

NO - Go to step 2.
Did customer report that the vehicle exhibited (currently or previously) a shudder or surge
condition? (This condition may also be described as engine flare, lack of acceleration, and/or
car shake.)
D
YES - Go to “Diagnostic Procedure 2: Special Case” in this TSB.
D
NO - Go to step 4 to verify that SR-16-006 has been completed for vehicles listed in that
