PROBLEM TO BE SOLVED: To stabilize the control for preventing the application of the excess load in an initial period of synchronization found in a conventional device and improve the durability of a synchronizer. SOLUTION: In this automatic transmission executing the synchronous feedback control by comparing a target input and output rotating frequency and an actual input and output rotating frequency in a manual transmission 10 for automatically gear-shifting by a shift actuator 50, and adjusting the load, a delay time of a constant time determined while considering a response delay time necessary for an indicated current value to be represented as the change of the actual input and output rotating frequency is determined in an initial period of the synchronous control, and the synchronous feedback control of a synchronizer 3 is executed after the delay time has passed. |
