Abstract
For setting selection gate positions for change speed in a gear-shift mechanism of an automatic gear transmission, a first actuator is activated to rotate a shift-and-select lever for shifting one of shift heads engaged therewith in its neutral position to a low or high speed side in a shift direction, and a second actuator is activated to effect movement of the shift-and-select lever in a select direction perpendicular to the shift direction in a condition where the shift head was shifted to the low or high speed side. The second actuator is deactivated when the movement of the shift-and-select lever in the select direction was restricted by engagement with the shift head shifted to the low or high speed side. When the second actuator was deactivated, an output value of a selection-stroke sensor for detecting operation of the second actuator is read out for setting a selection gate position of the shift head shifted to the low or high speed side based thereon.
