Code P2813 GMC Description

The Transmission Control Solenoid Valve Solenoid Valve is an electronic pressure regulator that controls transmission line pressure based on current flow through its coil windings. As 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 Transmission Control Solenoid Valve, which ultimately 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). The Diagnostic Trouble Code (DTC) is set when the Transmission Control Solenoid Valve Control Circuit commanded state does not match the actual state for greater than 1 s.
