What Is a Pressure Control Solenoid Malfunction?

Answer

A transmission solenoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied via the transmission computer or controller. Transmission solenoids are usually installed in a transmission valve body, Transmission Control Unit, or transmission control module. When it malfunctions, it can ruin a transmission if not repaired.

A Pressure Control Solenoid Malfunction occurs in engines when the solenoid valve regulates the oil discharge pressure in response to a signal sent from the Transmission Control Module. It may be caused by foreign material obstructing the mechanical function of the solenoid or the flow of the oil. It could also occur if the transmission fluid is very dirty.
