A range switchover apparatus includes a range switchover means operating device capable of switching over a switchover means, which switches over a shift range, among respective shift positions, a drive motor for driving the range switchover means operating device, a measuring device for measuring a time, during which the drive motor causes the range switchover means operating device to switch over between predetermined shift positions, a rotation control device for controlling the rotational speed of the drive motor, a correcting device for correcting the rotational speed by the rotation control device so that when a time measured by the measuring device differs from a target time in a predetermined range, the measured time becomes the target time, and a storage device for storing the rotational speed corrected by the correcting device. The range switchover apparatus prevents a change in rotational speed due to long term change from being generated in a motor for driving a switchover means in an automatic transmission.
