ABSTRACT:
A shift control mechanism is provided for a transmission or the like. The control mechanism prevents the transmission from being shifted directly from a forward speed to reverse or vice versa. A shift lever of the transmission engages a slider when shifting between a reverse position and a neutral position or between a forward position and the neutral position. The slider is mounted in a guide on a lockout plate with the slider being limited in movement to prevent the shift lever from moving beyond the next adjacent position of the transmission in any single motion. Thus, the transmission must always be shifted into neutral when shifting between forward and reverse.
