How does the EPC Electronic Pressure control solenoid work?
The EPC Electronic Pressure Control Solenoid. Today’s electronic transmissions use a control module to control transmission line pressure, shift timing and quality. It receives inputs from sensors like the MAF or MAP, VSS, and ECT and then compares them to information stored in its memory.
How to replace a pressure control solenoid valve in a transmission?
How to Replace a Pressure Control Solenoid Valve in a Transmission. Disconnect the battery. Remove the negative terminal with a socket set and wrench first, then remove the positive cable. Standing over the engine bay, remove the dipstick from the transmission. Slide under the vehicle with your tools. Place the oil pan under the transmission.
Why do I need to rebuild my transmission solenoid?
Rebuilding It The control solenoid is an essential component of the transmission system. It helps regulate the torque converter lockup, pressure control, and shifting and kickdown for passing gears. One common symptom of a faulty control solenoid is that your transmission may experience problems shifting gears.
How is the pressure of a transmission controlled?
Today’s electronic transmissions use a control module to control transmission line pressure, shift timing, and quality. It receives inputs from sensors like the MAF or MAP, VSS, and ECT and then compares them to the information stored in its memory. It then pulses this solenoid on and off to raise or lower line pressure according to demand.
Where can I get a transmission pressure solenoid replaced?
When the diagnoses is a failed transmission pressure control solenoid, the solenoid must be replaced. Replacing a transmission pressure conrol solenoid can be done by most any auto repair shop, automobile dealership service center or you can do-it-yourself “DIY”. Transmission Pressure Control Solenoid: REPLACEMENT COST
How to replace a pressure control solenoid valve in a PC?
Pull the two wires off the PCS and pull it off the fix plate. The PCS is fastened to the fix plate with tabs that you must depress before pulling it off, or with small screws you must first unthread. Affix the new PCS and hook up the two wires on the proper terminal tabs. Screw the fix plate back in position.
Why do you need a transmission power control solenoid?
Transmission power control solenoid — PCS — valves are duty cycle-controlled components that manage the pressure of transmission fluid. A PCS is required to prevent the transmission from seizing up from lack of fluid or bogging down as a result of too much fluid.
When do you know your transmission solenoid has gone bad?
While in motion, your vehicle will slip out of gear. Problems with the control solenoid are often accompanied by you seeing the check transmission light illuminated on your dashboard. Once you have verified that your transmission control solenoid has gone bad, you need to repair it immediately.
