Disclosed is a controller of a stepped automatic transmission. The stepped automatic transmission has a plurality of lock-up elements and performs downshift during coasting while an engine has a fuel cut-off state by changing over a pair of lock-up elements including an open side lock-up element and a lock-up side lock-up element. Downshift operation includes torque phase control and inertia phase control. The controller includes: a fuel cut-off recovery executing unit that is configured to perform recovery from the fuel cut-off state for an inertia phase control period; and a cylinder number restricting unit that is configured to restrict a count of cylinders recovered from the fuel cut-off state.
