A method of controlling the shifting of an automatic manual transmission is based on observer-based timing of different phases of the shift process. The observer-based control strategy includes simultaneous management of the engine throttle and transmission actuators. The torque characteristics of the transmission are also taken into consideration during control of the engine throttle, thereby minimizing shift time and wear on transmission components. The control strategy uses mathematical models called observers to monitor the value of inherent properties attributable to specific actuators and to provide signals used to implement parallel task execution.
