Transmission Identification
The PCM contains transmission solenoid body strategy data. When a new solenoid body or transmission is installed, the diagnostic scan tool must be used to retrieve the solenoid body strategy data and load it into the PCM. If the PCM is replaced and the PCM data cannot be inhaled or exhaled, the solenoid body identification and strategy must be loaded into the PCM. If the solenoid body information is not correct, transmission damage or driveability concerns can occur.
