PCM/TCM Software Updates May Address Shifting Problems on Chrysler 300

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.

This s/w fix was made to my 2010 300s. The issue, for the most part, subisided. Once in awhile I'll still get the 'clunk' noise from the trans.
