ABSTRACT:
A control apparatus for an automatic transmission capable of operating in an automatic shift mode in which a speed ratio is automatically selected based on driving conditions of a vehicle, and a manual shift mode in which the speed ratio is changed based on an upshift command and a downshift command by manual operation of a manual operation unit, the control apparatus includes a controller that operates in a jumping shift mode that is included in the manual shift mode and that is composed of a smaller number of shift speeds than a number of shift speeds of the automatic shift mode; wherein the controller performs a downshift from a shift speed of the jumping shift mode at a time when the downshift command is issued by an operation of the manual operation unit based on the shift speed of the jumping shift mode.
