Abstract
A control for enhanced manual shifting in a computer-assisted (48) vehicular splitter-type compound transmission (16) having a synchronized main section (16A) shifted by a manually operated shift lever (31) and a controller (42). The splitter section (16B) is located at the input end of the transmission, is provided with a three-position (L, H, N) actuator (46), and is commanded to a splitter-neutral position upon sensing an intent for a main section shift to neutral and remains in splitter neutral until the main section is reengaged to reduce the forces required to synchronize the main section.
