The electronic control of hydraulics in automatic transmissions and the engineering competition between Japan, Europe and the United States are discussed. Electronically-controlled automatic transmission in Japanese cars and an electronic-shift-points controller in Renault's automatic gearbox are described. A diagram is used to illustrate the layout of Renault's electronically-controlled automatic transmission. It is noted that using electronics and transducers, the control sector assures the selection of, and provides the means for changing gears in response to both the vehicle operating conditions and the wishes of the driver. The automatic transmission's control system, and the organization of the microcomputer's electronic circuitry is described. It is predicted that most cars on the road will have electronically-controlled transmissions by 1995.
