Zusammenfassung:PURPOSE:To enable shift-up operation even at the time of changing the running range by selecting the highest step as the optimum speed change step on detecting a change from the low-speed running range to the high-speed running range. CONSTITUTION:A processor 9a compares a selection signal SP with a running range SP0 detected one cycle previously and stored in RAM9e. If SP>SP0, a change to the high-speed range is discriminated to compare a car velocity V and a shift down boundary speed V2d, and when V>=V2d, the optimum speed change step G0 is the third speed. The processor 9a compares the optimum speed change step G0 with the present speed change step GP, and if G0
