A sensor device is provided for detecting a shifting position of a vehicle transmission. The vehicle transmission includes a transmission chamber, in which transmission elements are arranged. The sensor device includes a bar element, which extends from the transmission chamber into a secondary chamber sealed off from the transmission chamber and is arranged such that the bar element can be moved in dependence on the shifting position. The bar element has an interface arranged in the transmission chamber for coupling the bar element to a transmission element positioned in dependence on the shifting position and an accommodating segment arranged in the secondary chamber. The sensor device also has a transducer element, which is attached to the accommodating segment of the bar element. The sensor device also has a detecting device for detecting a position of the transducer element depending on the shifting position or a motion of the transducer element depending on a change in the shifting position.
