Component Description

Sensors and Switches

The TCM (Transmission Control Module) controls the electronic functions of this transmission. The TCM (Transmission Control Module) receives input signals from engine and transmission sensors and uses these inputs to control line pressure, shift time, TCC (Torque Converter Clutch) and shift solenoids.






Solenoid Body

The solenoid body contains 7 solenoids: 5 shift solenoids (SSA (Shift Solenoid A), SSB (Shift Solenoid B), SSC (Shift Solenoid C), SSD (Shift Solenoid D) and SSE (Shift Solenoid E)), 1 TCC (Torque Converter Clutch) solenoid and 1 LPC (Line Pressure Control) solenoid. The TFT (Transmission Fluid Temperature) sensor is also located in the solenoid body. The solenoid body is serviced as an assembly.

The solenoid body has a unique strategy data file that must be downloaded to the TCM (Transmission Control Module). There is a 7- digit solenoid body identification and a 13-digit solenoid body strategy for each solenoid body. Any time 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 TCM (Transmission Control Module).

If the TCM (Transmission Control Module) is replaced and the TCM (Transmission Control Module) data cannot be inhaled or exhaled, the solenoid body identification and solenoid body strategy must be downloaded into the TCM (Transmission Control Module).

This transmission uses 3 types of solenoids: on/off, normally low and normally high. On/Off solenoids open or close hydraulic passages based on the voltage signal it receives. Normally low solenoids provide hydraulic pressure proportional to supplied current. A normally low solenoid will not provide pressure without current, while it will supply high pressure with high current. Normally high solenoids provide pressure inversely proportional to supplied current. Normally high solenoids provide full output of pressure with no current and very low pressure with high current.
