Code P2835 Description

The P2835 diagnostic trouble code refers to the Shift Fork 'A' Position Circuit Intermittent. In vehicles with automatic transmissions, the shift fork is responsible for engaging and disengaging gears within the transmission. The position circuit is a system that monitors the position of the shift fork and communicates this information to the vehicle's engine control module (ECM). When the ECM detects an intermittent issue with the shift fork 'A' position circuit, it triggers the P2835 code.
