This gear shift lever switch is an electrical component mounted on the gearbox housing. It signals the transmission control unit when the operator moves the shift lever, enabling the correct gear engagement sequence. The switch completes or interrupts a circuit based on lever position, which the control unit interprets to manage clutch and gear actuation. A failing switch can cause erratic shifting, failure to engage a selected gear, or a no-start condition if the safety interlock is triggered. As an original AGCO part, the switch body and contact geometry match the factory housing and lever mechanism, ensuring the correct actuation travel and electrical contact pressure without modification.
