This patent describes a method for controlling shifting of an automated mechanical transmission system. It comprises: a mechanical transmission including a shift actuator, a fuel controlled engine, a nonpositive coupling drivingly interposed the engine and the transmission, and a central control unit (50) effective to receive input signals indicative of the status of the transmission system including signals indicative of the rotational speeds of transmission shafts and signals indicative of the positioning of transmission jaw clutch members and to process same in accordance with logic rules to issue command output signals to a plurality of system actuators, including the shift actuator and a non-positive coupling actuator, the method including the steps, responsive to sensing a required shift from transmission neutral into a selected gear ratio, of causing the nonpositive coupling to be disengaged, then causing the jaw clutch members associated with the selected gear ratio to rotate at a substantially synchronous speed and then causing the jaw clutch members to be continuously urged into positive engagement.
