摘要：
A neutral-reverse shift control actuator is provided in a countershaft transmission. The actuator is operatively connected through a resilient detent mechanism (136,138,140) to a forward shift control mechanism. During a neutral-reverse shift maneuver, the drive connection partially manipulates the forward synchronizer, such that synchronization between the input and output shaft is achieved during a reverse shift maneuver. During a five-six or six-five shift, a detent structure (152) is available to reduce the 3-4 neutral force of the centering spring (150) in the shift control mechanism.
