PROBLEM TO BE SOLVED: To provide a speed change control device of a transmission capable of inhibiting delay when speed change control is made by controlling a plurality of speed change clutches and a plurality of changeover clutches. SOLUTION: The control device of the transmission comprises a plurality of speed change gear pairs provided between a first rotary member and a third rotary member and between a second rotary member and the third rotary member, the two power transmission path changeover clutches separately provided between the first rotary member and the second rotary member and the plurality of speed change clutches individually provided on the plurality of speed change gear pairs, and performs speed change control by changing connection and disconnection of the plurality of speed change clutches and by changing engagement and disengagement of the two power transmission path changeover clutches. The control device of the transmission has a changeover means (step S1 or step S20) for changing first speed change control for blocking power transmission through control of the two power transmission path changeover clutches and second speed change control for continuing the power transmission through control of the two power transmission path changeover clutches.
