ABSTRACT:
A command assembly for controlling a splitter in a transmission allows shifting between first and reverse-low gears while the splitter is engaged without requiring the splitter to cycle during the shift. The command assembly creates a signal path for a split enable signal that keeps the transmission in the split mode as long as the transmission engages a low rail of a main drive box. By creating a separate signal path for the split enable signal when the transmission is operating in split mode, the splitter does not need to be cycled when the driver shifts between first and reverse-low gears.
