Abstract
A kick-down circuit for an automatic change-speed transmission with a kick-down control member transmitting a kick-down control signal when an accelerator or gas pedal is floored and with at least one gearshift control element operating in dependence upon a transmission output speed and a position of the gas pedal for an auxiliary operating force of a shift actuating member participating in a shifting between a higher gear and a lower gear. The gearshift control element, upon an occurrence of the kick-down control signal, may be brought into its position for the lower gear under the effect of an auxiliary control force dependent upon a position of the gas pedal. The kick-down control signal is temporally limited independently of the position of the gas pedal.
