    Abstract: A manual transmission comprising a first pivot member operatively connected to a first coupling unit on an output shaft and is selectively rotatable to drive the first coupling unit between first, neutral and second positions. A second pivot member is operatively connected to a second coupling unit on the output shaft and is selectively rotatable to drive the second coupling unit between first, neutral and second positions. A first shift rail is operatively connected to the first pivot member and is adapted to slide axially within a shift rail guide in response to rotation of the first pivot member and a second shift rail is operatively connected to the second pivot member and is adapted to slide axially within the shift rail guide in response to rotation of the second pivot member. The first and second shift rails each comprise a lock-out detent in facing relation to one another. A lock-out plunger is positioned within the shift rail guide between the first and second shift rails and is adapted to move between a first and a second locking position only when the first and second coupling units are in the neutral position. In the first locking position, the plunger lockingly engages the lock-out detent in the first shift rail to restrict axial movement of the first shift rail without impeding axial movement of the second shift rail. In the second locking position, the plunger lockingly engages the lock-out detent in the second shift rail to restrict axial movement of the second shift rail without impeding axial movement of the first shift rail.

    Abstract: A gear transmission with overtop or overdrive for automotive vehicles includes an overdrive gear mechanism mounted immediately after the rear end wall of a transmission case. The overdrive gear mechanism includes a pair of overdrive gears, one located on the output shaft of the gear transmission and the other on the countershaft of the gear transmission, operable to rotate the output shaft at a higher rotational speed than the input shaft. An overdrive synchronizer assembly is mounted rearwardly of the overdrive gears such that the direction for actuating the overdrive synchronizer assembly coincides with the direction that a gear shift lever of the vehicle is shifted to obtain the overdrive position.
