SYMPTOM/CONDITION:
Some customers may notice that the engine can achieve higher RPM's than normal after an unusual shift condition. This condition can happen if the driver of the vehicle shifted the vehicle from drive to neutral then back to drive (D-N-D) with their foot on the accelerator while driving at interstate highway speeds. The updated software corrects this condition.

DIAGNOSIS:
Using a Scan Tool (wiTECH or StarMOBILE) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as designed. If DIG's are present record them on the repair order and repair as necessary before proceeding further with this bulletin.

If the vehicle operator describes or experiences the Symptom/Condition, perform the Repair Procedure.
