What does code P2794 mean?

Q: What does code P2794 mean?

Gear Shift Direction Circuit Low. P2794 indicates that the transmission control module (TCM) has detected a low-voltage condition on the electrical circuit that controls the gear shift direction solenoid or actuator. This circuit is responsible for commanding the transmission to shift into the correct gear range, and a low signal typically means the TCM sees voltage below the expected threshold, which can prevent proper shift direction commands from being executed.
