Abstract
In a double clutch transmission, especially for a motor vehicle, it is necessary for the completely satisfactory shifting sequence to engage and disengage the clutches alternately; in order that such a sequence is assured, differential pressure switches are provided which include a signalling device that indicates end positions of the clutches to an electronic control installation for evaluation purposes.
