- Delayed shifting / not wanting to shift until about 3500 rpm, when driving straight. (2.4L only)
- Shuddering or bumps while moving and stepping on the accelerator pedal. (2.4L only)**
- A delayed up-shift. This condition may be noticed when cornering with a light acceleration and speeds up to 40 KPH (25 MPH) causing high engine rpm.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all related systems are functioning as designed. If Diagnostic Trouble Codes (DTCs) or symptom conditions, other than the ones listed above are present, record the issues on the repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes the symptom/condition listed, perform the Repair Procedure.
REPAIR PROCEDURE:
NOTE: Install a battery charger 
to ensure battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during the flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
- Reprogram the TCM with the latest available software. Detailed instructions for flashing control modules using the wiTECH Diagnostic Application are available by selecting the application’s “HELP” tab.
- Clear any DTCs that may have been set in other modules due to reprogramming. The wiTECH application will automatically present all DTCs after the flash and allow them to be cleared.
