<p>PURPOSE:To obtain a practical acceleration state during running at the top-speed step by operating a shift-down switch before the operation of a kick-down switch at the time of acceleration for shifting one step down once from the top- speed step. CONSTITUTION:A kick-down switch 304 is provided to detect the approximately maximum point of the step-on volume of the accelerator pedal 300 together with a shift-down switch 303 to detect the step-on volume a fixed volume less than that of the accelerator pedal detected by the switch 304. When the kick- down switch 304 is on, a drive solenoid 124a of a kick-down valve to switch over the top-speed step (overdrive speed-change step) to the low-speed step is electrified. In this construction, when the shift-down switch 303 is on, a solenoid 217a for overdrive-releasing to switch over from the top-speed step to one step lower speed is electrified.</p> |
