SYMPTOM/CONDITION:
Some customers may experience a less than desirable shift quality or the vehicle stuck in
a fixed gear during a limp in mode.
The following enhancement is included in the software update:
•
Improved transmission shift quality and allowing the transmission to shift multiple
gears during a limp mode condition.
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 one listed 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 above or if the technician finds any
DTC, 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.
1. Reprogram the TCM with the latest software. Detailed instructions for flashing control
modules using the wiTECH Diagnostic Application are available by selecting the
application’s “HELP” tab.
2. Clear all DTCs that may have been set in any module due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow them
to be cleared.
NOTE: Do not clear the adaptation memory cells in the TCM’s memory. Clearing the
memory cells may cause the transmission to not shift smoothly until they
can be fully relearned.
3. Verify the Powertrain Control Module (PCM) is programmed with the latest available
software. Refer to all applicable published service bulletins for detailed repair
procedures and labor times regarding updating the PCM software.
