Abstract
A control system and method for a semi-automatic mechanical transmission system (10) is provided for sensing rolling start conditions (OS>REF, GR=N, (CLUTCH MANUAL DISENGAGED=TRUE)) and upon sensing such conditions, allowing operator request for a direct shift into an appropriate rolling start gear ratio (GR.sub.RS) determined as a function of current and/or expected output shaft speed (GR.sub.RS .gtoreq.ES.sub.IDLE /OS).
