SYMPTOM
Under certain driving conditions some client may experience a firmer-than-expected upshift from 2nd to 3rd gear.
POSSIBLE CAUSES
The TCM software is not optimized for a consistent 2nd to 3rd upshift under all conditions.
CORRECTIVE ACTION
Update the TCM software to get optimal performance out of the transmission, clear any DTCs, and do the PCM idle
learn procedure.
NOTE: After completing the software update, check the Idle Learning signal in the PGM-FI Data List. If it reads NOT
COMPLETE, check the Target Idle Torque Correction Learning value. If it reads 65 N•m (47.9 lb-ft) you need to
update the PCM. Refer to Service Bulletin 15-038, Hesitation, Surge, High Idle, or Auto Idle Stop Does Not Work, for
software update information. If the value reads 12 N•m (8.8 lb-ft), complete the idle learn as according to the service
information.

REPAIR PROCEDURE
1.
Update the TCM software with the MVCI. Refer to Service Bulletin 01-026, Updating Control Units/Modules.
NOTE:
•
•
On vehicles equipped with auto idle stop, the MVCI may indicate error code 56 during the update. If you see
the error code, open the hood, disable auto idle stop using the switch in the center console area, and retry the
update again leaving the hood open.
After completing the software update, check the Idle Learning signal in the PGM-FI Data List. If it reads NOT
COMPLETE, check the Target Idle Torque Correction Learning value. If it reads 65 N·m (47.9 lb-ft) you
need to update the PCM. Refer to Service Bulletin 15-038, Hesitation, Surge, High Idle, or Auto Idle Stop Does
Not Work, for software update information. If the value reads 12 N·m (8.8 lb-ft), complete the idle learn as
according to the service information.
2.
Clear any stored DTCs with the HOS.
3.
Do the PCM idle learn procedure:
•
•
•
•
•
•
Make sure all electrical items (A/C, audio unit, rear window defogger, lights, etc.) are turned off.
Start the engine, and let it reach operating temperature (the cooling fans cycle twice).
Let the engine idle for 10 minutes with the throttle fully closed.
Turn the ignition to OFF.
Jump the SCS line with the HOS.
Wait 60 seconds, then exit the SCS mode.
