Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Transmission Identification
The solenoid body has a unique strategy data file that must be downloaded to the PCM. There is a 12-digit (6R100) or 8-digit (6R140) 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 PCM. If the PCM is replaced and the PCM data cannot be inhaled or exhaled, the solenoid body identification and solenoid body strategy must be downloaded into the PCM.
