Abstract: In an automatic transmission control device of the invention configured to start an increase in engagement pressure of a start-up engagement element, when a determination threshold value for determining that a turbine rotational speed has reduced is reached or exceeded, the determination threshold value when a selection operation from a non-traveling range to a traveling range is made before a prescribed period of time from starting of an engine has elapsed, is increased and set greater than the determination threshold value when the selection operation is made after the prescribed period of time has elapsed.
