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.
