Abstract
A vehicle transmission of the type having a main shaft and a parallel counter shaft with a plurality of selectable gear trains therebetween. The axis of the engine crankshaft is disposed perpendicular to intermediate portions of the main shaft and the counter shaft, with the low speed gear trains and high speed gear trains positioned on opposite lateral sides of the crankshaft. This results not only in a reduced size of the transmission in the axial direction of the crankshaft but also in a reduced lateral size of the transmission, as compared with a transmission in which the crankshaft is connected in series to the transmission main shaft. A synchro mechanism is mounted on the counter shaft and a shift drum for operating the synchro mechanism is positioned parallel to the counter shaft. This insures a space for disposition of the synchro mechanism between gears of the relatively large diameter gears on the counter shaft and ensures a smooth shifting operation, without an increase in the lateral size of the transmission due to the shift drum.
