Solenoid Body

The solenoid body contains 7 solenoids: 5 shift solenoids (SSA, SSB  , SSC  , SSD  and SSE  ), 1 TCC  solenoid and 1 LPC  solenoid. The TFT  sensor is 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  . There is a 7-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 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  .

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.
