Abstract
An electronically controlled transmission in which a shift actuator for driving a sleeve of a roller synchro mechanism and a throttle actuator for an engine are electronically controlled. The shift actuator is comprised of a drum type actuator of a simple structure comprising a shift drum and a shift fork. The use of the roller synchro mechanism ensures that only a small driving force for the shift drum is required, which makes it possible to provide a reduction in size of the shift actuator. In addition, a shift lever for operating a shift switch for producing the shifting instruction signal is mounted on either left or right side of the steering wheel. This ensures that the shifting-up and shifting-down signals can be produced by one of the driver's hands, leading to an improvement in operability of the shift lever.
