Solenoid Body

Transmission Solenoid Body:

Solenoid Operation Chart.:

PURPOSE
The transmission solenoid body is used by the Powertrain Control Module (PCM) to Regulate Electronic Pressure Control (EPC) pressure, transmission shift points, and converter lock-up on the E4OD automatic transmission.


OPERATION
The PCM controls the E4OD transmission operation through four on/off solenoids and one Variable Force Solenoid. These solenoids and Transmission Oil Temperature (TOT) sensor are part of the transmission solenoid body and are not serviced individually. The TOT sensor is used by the PCM to monitor transmission temperature.The five solenoids are used to control EPC for transmission shift and converter lock-up control.
