If you notice rougher shifting on 6.6L Duramax or 6.0L Powerstroke vehicles after installing the tune to
your engine computer, you can help your transmission adjust to the additional horsepower by follow-
ing the Transmission Relearn Process described below. Your transmission will also automatically adjust
after about 150 miles of regular driving if you prefer not to complete the relearn process.
