If you experience rough shift and/or shuddering during gear shifting, software updates to the powertrain control and transmission control modules (PCM and TCM) are available which may address these problems. On higher mileage vehicles, a mechanical failure may exhibit similar symptoms. Proper diagnoses should be performed before any repairs or software upgrades are attempted.
