DTC codes / P07xx · Transmission / P0769
P0769 indicates that the transmission control module has detected an intermittent electrical fault in the circuit for shift solenoid D, which controls a specific gear change in the automatic transmission. The computer monitors the solenoid's current draw and response time, and it sets this code when the signal drops out or behaves erratically without being completely open or shorted.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
