ABSTRACT:
A control device for an automatic transmission includes: a control portion that executes a neutral control to release the friction engagement element if a progressing position of the automatic transmission is selected, and a state of the vehicle satisfies a certain condition; a detection portion that detects degree of deceleration of the vehicle before the neutral control is executed; and a releasing portion for releasing the friction engagement element to be in a released or semi-released state in accordance with a shift of the automatic transmission if the degree of deceleration is greater than a predetermined degree.
