This service is required when needing the calibration to match the year model of the vehicle.
If your vehicle is a 15-19 model- the PCM and TCM operating systems need to match for communication purposes. This can be done with the HP70 and HP90 Transmissions. YOU WILL need to send us your VALVEBODY from the transmission in order for us to flash the TCM with the correct operating system.
When placing an order, please notate the vehicle year model and what year model the transmission controller is so we can match it to the vehicle.
