Abstract

A motor vehicle transmission with at least one sensor (15), associated with the motor vehicle transmission, for picking up measurement signals at the motor vehicle transmission and transmitting them by a wireless unit to a transmission control unit (12) of the motor vehicle transmission. In each case, an RFID-responder (16) is associated with each sensor (15), which transmits the respective measurement signals concerned to an RFID-reader (17), associated with the transmission control unit (12). The RFID-reader (17) transmits wirelessly to the RFID-responder (16), associated with the sensor (15) concerned, electrical energy for operating the sensor (15) and for operating the RFID-responder (16) associated with the sensor (15).
