A torque sensor system for a transmission and other powertrain components in a motor vehicle includes a receiver and a transmitter. The content signals, broadcasted by the broadcasting device include screen related action codes which include device type, action type and the detail action information. The receiver receives and processes signals from a number of transmitting sources to provide an estimate of a position of the metering device. Additional isolated paths may be provided to provide bi-directional exchange of information between the first and second circuit parts andor to provide for the exchange of additional information relevant to control. As such, the pet bag may receive and hold a pet therein and the pet bag can be hand or shoulder carried or trolleyed. At least a pair of each pin of the wheel gear and each cam groove of the barrel cam are engaged with each other, and the shift drum is rotated by the actuator via the barrel cam and the wheel gear, to thereby change the speed change stage of the transmission.
