ABSTRACT:
A control apparatus for an automatic transmission including a gear-type transmission mechanism connected to an output shaft of a motive power source, the gear-type transmission including plural frictional engagement elements. The control apparatus senses a power-on downshift in which the frictional engagement elements are engaged during a downshift in a driving state of the motive power source, controls the motive power source so that in the power-on downshift an output of the motive power source is reduced, counts a time during which an input rotational speed of the transmission mechanism approximates an after-shift synchronous rotational speed, and controls the motive power source so that, if the time exceeds a predetermined time while the output of the motive power source is reduced, recovery from the reduction of the output of the motive power source is attained.
