A method for controlling an automatic mechanical transmission system (2) of the type comprising a throttling control device (19) controlled heat engine (12) a nonpositive coupling such as a friction master clutch (14) and a jaw clutch type multispeed mechanical transmission (10) utilizing a digital microprocessor (100) based electronic controller (30) is provided. The method includes providing logic routines for the microprocessor including a high priority algorithm for processing current inputs to determine current system status and to generate outputs including command outputs based upon current system status and a low priority algorithm for providing a signal indicative of the currently desired gear ratio to the high priority algorithm. The logic routines perform the low priority algorithm on a continuous loop basis and interrupting the low priority algorithm to perform the high priority algorithm at least twice during a critical control period corresponding to the time required for the system actuators to respond to a command output.
