ABSTRACT:
A control system and method for an automated mechanical transmission system (310) operable in a hold mode of operation (H) is provided. When operating in the hold mode of operation, if override conditions (ES>ES.sub.MAX, ES<ES.sub.MIN, cruise control resume mode) are sensed, the hold mode is overridden and a shift from the currently engaged gear ratio (GR.sub.C) into a desirable gear ratio (GR.sub.D) is automatically initiated.
