ABSTRACT:
A method and device for controlling a plurality of magnet valves in an automatic transmission having a fluid torque converter, an anxiliary transmission equipped with a plurality of gear trains for transmitting the output torque of said torque converter to drive wheels through one of the selected gear trains, a plurality of shift valves to select said gear trains, and a plurality of magnet valves to drive said shift valves, wherein at least one of the magnet valves, which is subsequently driven to take an open-state at a time the gear train shifts up from the lowest speed to the second lowest speed, is closed at about the time of stalling of said torque converter and those magnet valves other than said closed magnet valve are opened after a short time delay after said magnet valve is opened when the vehicle velocity reaches the second lowest speed.
