Transmission Identification

The solenoid body has a unique strategy data file that must be downloaded to the TCM. There is a 12-digit solenoid body identification and a 13-digit solenoid body strategy for each solenoid body. When a new solenoid body or transmission is installed, the diagnostic scan tool must be used to obtain the solenoid body data file and download it into the TCM. If the TCM is replaced and the TCM data cannot be inhaled or exhaled, the solenoid body identification and solenoid body strategy must be downloaded into the TCM.
