ABSTRACT:
A semi-automatic shift implementation system (100) for a manually shifted, output-splitter-type compound transmission (10) having gear ratios selectively engaged and disengaged by jaw clutches (48, 50) selectively positioned by a shift lever (57). The system will sense a main transmission section (12) neutral condition, a master clutch disengaged condition, and a target gear ratio (GR.sub.T) and will automatically cause the splitter clutch (80) to disengage until the main section is reengaged and the system engine (102) to achieve or dither about a substantially synchronous speed for engaging the target ratio.
