Preselect prohibit valves (162, 164) are interposed the selector switch and actuation devices to block the transmittal of said signals and to maintain the transmission in the currently engaged gear ratio until operator actuation of a prohibit release switch (172) provides a signal (C) indicating operator request for execution of the preselected gear change.
