Transmission Relearn Process

After completing the download process, it is recommended on a 6.6L Duramax with an
automatic Allison and a 6.0L Ford Power Stroke with an automatic Torque Shift trans-
mission, that the transmission be relearned. Relearning the transmission can help the
transmission adjust to the higher levels of power offered by the GT resulting in a better
shifting transmission. Follow the vehicle specific procedures below to relearn the follow-
ing transmissions.
