ECM Calibration: Enhancement to Shifting Performance
Repair Procedure
1. Test drive the vehicle and confirm there is a harsh shift on acceleration below 20 mph.
NOTE
Confirm correct transmission fluid level by following the procedures in the Repair Manual
BEFORE reprogramming the ECM (PCM) since incorrect fluid level can also cause shifting
issues.
2. Check for the Authorized Modifications Label affixed to the vehicle in the location shown in
Figure 1. Confirm if the ECM (PCM) calibration has been updated. If the calibration ID listed is
NOT the latest ECM (PCM) calibration — go to step 3.
