The gear required by the Engine Control Module (ECM) does not match the actual gear when driving
The Pressure Control (PC) Solenoid Valve is an electronic pressure regulator that controls transmission line pressure based on current flow through its coil windings. As the current flow is increased, the magnetic field produced by the coil moves the solenoid’s plunger further away from the exhaust port. Opening the exhaust port decreases the output fluid pressure regulated by the PC solenoid valve, which decreases line pressure. The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM).
