In an automatic transmission shift control device, a rocking lever and a second biasing unit are provided for holding a selector lever (10) in a shiftable condition when the selector lever is in one of gear positions other than a parking position. A first biasing unit (37) is provided for holding the selector lever in a locked condition when the selector lever is in the parking position. A solenoid (30) is provided for releasing the selector lever from a locked condition when energized.
