Abstract
A partially automated mechanical transmission system (92) having a mechanical transmission (10) with a lower group (first-eighth) of manually shifted ratios and an upper group (ninth-tenth) of ratios with automatic shifting between ratios in the upper group and requiring manual shifting between groups. Control logic is provided to sense a driver intention to shift into the automated upper group of ratios and to initiate automatic engine synchronizing for engagement of one of said ratios in said upper group.
