Use a scan tool to view and record the Transmission Control Module - End Model Part Number in the original TCM prior to starting the TCM reprogramming procedure.

If you are unable to communicate with the TCM during step 1 and do not have a CD-ROM containing characterization data for this transmission. Take a picture of the QR Code label and send to TCSC. TCSC will retrieve the data from the label and send back the information needed for Transmission Control Module-Configuration.
