What is EPC in transmission?
(EPC) Electronic Pressure Control Today’s electronic transmissions use a control module to control transmission line pressure, shift timing, and quality. The EPC controls a pressure regulating spool valve and spring that holds or releases fluid pressure, typically back to the transmission’s sump.
How does a control module in a transmission work?
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 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.
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 does an electronic hydraulic control module work?
Electronic Hydraulic Control Module (TECHM) incorporates the TCM, Solenoids, Pressure Switches (eliminated in 2012 GEN2), TFT Sensor and it is bolted to the valve body. Internal Mode Switch (IMS) equipped 2 wire Hall effect input and output speed sensors Performance Algorithm Shifting (PAS) programming

What happens when a powertrain control module fails?
A powertrain control module also controls engine and transmission functions. It is responsible for timing shifts, shift feel and engaging the clutch. When your PCM fails, your transmission is likely to stop shifting, shift too soft or harsh or cause complete transmission failure. Bad transmission control module symptoms:
