Solenoid Body 

This transmission uses 2 types of solenoids: CIDAS and variable force solenoids.

The solenoid body contains 8 solenoids: 6 shift solenoids SSA, SSB, SSC, SSD, SSE and SSF, 1 TCC solenoid and 1 LPC solenoid. The TCC solenoid is identified by the green electrical connector. The LPC solenoid is identified by the blue electrical connector. The TFT sensor is located in the main control.

The solenoid body has a unique strategy data file that must be downloaded to the PCM. 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 scan tool must be used to get the solenoid body strategy 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.

Shift Solenoids

This transmission utilizes six shift solenoids (A-F) that are normally low CIDAS. Unlike previous shift solenoids they are mechanical in nature in that no transmission fluid passes through them. CIDASs use an armature/pin assembly that moves a control valve in the main control valve body to control and apply hydraulic fluid pressure. Each clutch (A-F) has a corresponding shift solenoid (A-F) that is directly proportional in that zero current equals zero pressure and maximum current equals maximum pressure. Since there is no pressure with zero current if the power is interrupted to the shift solenoids none of the clutch packs are able to engage.
