Abstract
A transmission, such as an automated manual transmission for a motor vehicle, with at least one shift group, such that the shift group or each shift group comprises a shift rail which actuates a shift fork that co-operates with a shift sleeve of the shift group concerned. Associated with the shift rail of the shift group or of each shift group there is a sensor that moves together with the respective shift rail relative to a corresponding measurement receiver such that in the area of at least one shift group, a first relative position between the measurement receiver and the sensor in the actuation direction and a second relative position between the measurement receiver and the sensor perpendicular to the actuation direction of the shift rail concerned can be detected, and from the second relative position, an evaluation device deduces system conditions of the shift group concerned.
