Abstract: A kick-down circuit for automatic change-speed transmissions, with a kick-down control member transmitting a kick-down control signal when an accelerator pedal is "floored" and with at least one gearshift valve for the operating pressure of a shift-actuating member participating in a shifting-over between a higher gear and a lower gear. The gearshift valve is actuatable by a control pressure dependent upon a driving speed along the lines of an "upshifting" and by a control pressure dependent upon a position of the gas pedal along of the lines of a "downshifting." Upon the occurrence of the kick-down control signal, under elevation of the control pressure dependent upon the position of the accelerator pedal, the gearshift valve may be brought into a position for the lower gear. The elevation of the control pressure acting along the lines of the "downshifting" triggered by the kick-down control signal is temporally limited independently of a position of the accelerator pedal.
