Abstract
In an automatic transmission for an automotive vehicle, an operating area covered by a high gear ratio is extended toward low vehicle speed side and the high gear ratio is released in response to the opening degree of the throttle and vehicle speed. The high gear ratio is released when the vehicle speed value is lower than a predetermined vehicle speed value and the opening degree of the throttle is larger than a predetermined opening degree.
