A manually operated automotive transmission includes an input cluster shaft that carries a reverse input pinion, a countershaft rotatably mounted parallel to the input shaft, a synchronizer clutch including a clutch sleeve defining reverse output gear slidably mounted on the cluster shaft and continually drivable connected to the countershaft, a reverse idler shaft, a first slidable reverse idler continually in meshing engagement with the reverse pinion, a second fixed idler pinion continually engaged with the reverse output gear. The reverse idlers are rotatably mounted on the idler shaft and define clutch teeth, which are brought into engagement as the slidable idler is moved by the vehicle operator to the reverse drive position and are disengaged as the vehicle operator selects forward drive ratios and the neutral position. |
