Zusammenfassung:	A multiple shift fork, single shift rail assembly reduces weight and complexity in manual and dual clutch transmissions. In a first embodiment, a stationary shift rail includes pluralities of detenting recesses and cooperating detent assemblies are mounted on the shift forks. Associated actuators translate the shift forks and synchronizer clutches. In a second embodiment, the detenting recesses reside on the outside surface of the shift forks and the detent assemblies are mounted in the transmission housing. In a third embodiment, one shift fork is slidably mounted on the shift rail and includes an external detent assembly. The shift rail itself translates and includes detenting recesses and a second shift fork connected thereto.
