This patent describes a method for controlling a vehicle automatic mechanical transmission system for devices having an operator actuated throttle pedal, a throttle-controlled engine, a transmission having gear ratio combinations selectively engageable between a transmission input shaft and a transmission output shaft, the transmission input shaft being operatively connected to the engine by means of a selectably engageable and disengageable friction coupling, the automatic mechanical transmission system comprising an information processing unit having means for receiving input signals including (1) an input signal indicative of the rotational speed of the engine; and (2) an input signal indicative of the operator's setting of the throttle pedal, the processing unit including means for processing the input signals in accordance with a program for generating output signals whereby the transmission system is operated in accordance with the program including a command output signal for control of the engine throttle device, and means associated with the transmission system effective to actuate the transmission system to effect engagement of the gear ratio combinations in response to the output signal from the processing units.
