Abstract

A control (68) for controlling the input section (12) of a manually shifted compound synchronized transmission (10) of the type comprising the splitter type input section (12) connected in series with a manually shifted synchronized multi-speed main transmission section (14) is provided. The control is effective upon sensing disengagement of the master clutch (20) and nonengagement of the main transmission section (14) to cause the input section (12) to be shifted to and maintained in the not engaged (N) position thereof and thereafter to cause the input section to be shifted to the preselected ratio thereof (H or L). The control is also effective with the main transmission section in the disengaged position upon engagement of the master clutch to momentarily cause the input section to be shifted to one of the engaged ratios thereof allowing the synchronized jaw clutches of the main transmission section to be engaged in start-from-stop operations.
