摘要： A control arrangement for an automatic change-speed transmission which is series-connected with an output of a driving engine. A gearshift control slide valve, a manually operable range selection control slide valve, and a gear-holding control slide valve operating in dependence upon a modulating control pressure related to the torque of the driving engine are connected in such a manner that the gearshift control slide valve is held in a position for a higher gear if the driving engine is in an idling position and the range selection control slide valve is in a position for a forward gear range. A downshift control member, operable by a control linkage of a power control of the driving engine affects the modulating pressure to be made effective at the gear-holding control slide valve in such a manner that, upon operating the control linkage from an idling position, the gear-holding control slide valve and gearshift control slide valve are brought into their positions for the lowest gear. A pressure regulating valve adjusts a vacuum pressure effective on a modulating pressure control slide valve in dependence upon positions of the control linkage, and the downshift control member affects the vacuum pressure to be brought to bear on the modulating pressure control slide valve.
