    • PROBLEM TO BE SOLVED: To provide a change gear control device of a multistep automatic transmission wherein response delay is prevented from occurring at shifting gear. SOLUTION: The gear shift control device of the multistage automatic transmission of a twin clutch type is provided with a gear shift commanding means, a gear shift commanding output means and a pre-shift motion detecting means. The gear shift control device performs a pre-shift motion for shifting from a gear shift step of transmitting a driving torque via a first clutch or a second clutch to another gear shift step of connecting a shift clutch corresponding to other gear shift step connecting the other clutch not transmitting the torque based on a gear shift motion starting command from the pre-shift motion detecting means, disconnects the clutch transmitting the driving torque based on the gear shift command from the gear shift command output means, and connects the other clutch not transmitting the driving torque so as to shift gear.
