Software updates to the Powertrain Control Module (PCM) are available that can improve shift quality for rough up and/or down shifts. On higher mileage vehicles, other problems may cause shifting issues. Diagnoses may be required to isolate the cause. Anytime major transmission repairs are made the PCM software should be checked and updated as necessary.
