ABSTRACT:
A control system and method for controlling start-from-stop operation in an automated mechanical transmission system, including a multiple-speed change-gear transmission (10) having a lowest grouping of ratios (first-fourth) suitable for start-from-stop operation, is provided. Upon a request or requirement for a shift into a default start ratio, the system controller (106) will cause initiation of a shift into the highest gear ratio (fourth) of the lowest group of ratios.
