A controlling device for automatic speed change mechanism is disclosed in which acceleration efficiency and fuel economy are simultaneously achieved. The device of the present invention is constructed such that plural sets of predetermined speed change programs are provided for indicating the relationship among the increase of driving power, that is, the opening degree of the throttle valve, the speed of the automobile and the speed change step. Based on the selected program information, the controlling of the speed change is carried out, while automobile height detection devices are provided for emitting electric signals corresponding to the distance between the surface of the road and the body of the automobile. Based on the height of the automobile body detected by the automobile height detecting device, a switch-over to a proper speed change program is carried out. Thus by switching over to a proper speed change program in response to the detected height of the automobile body, the most proper speed change step can be selected without aggravating the acceleration characteristics and the fuel economy.
