DTC codes / P27xx · Transmission / P2737
P2737 indicates that the transmission control module (TCM) has detected an abnormal condition in the electrical circuit for pressure control solenoid 'F', which is used to regulate hydraulic pressure inside the automatic transmission. The TCM monitors the solenoid's commanded current versus the actual current or pressure response and sets this code when the circuit's performance falls outside the expected range, indicating a fault in the solenoid, its wiring, or the hydraulic system it controls.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
