ABSTRACT:
A gearbox of a front wheel drive vehicle, having a transverse engine, includes a hollow main shaft carrying gears corresponding to different speeds, and has a driving input shaft extending therethrough so as to be rotatable relative to the hollow main shaft, with the driving input shaft having an end gear beyond the end portion of the hollow main shaft. An output shaft in the gearbox has output shaft gears rotatably mounted thereon, with the output shaft gears being permanently engaged with the main shaft gears. Synchronizers fix selected ones of the output shaft gears with the output shaft. A speed reducer is provided, and includes a secondary shaft that is parallel with the hollow main shaft. Two speed reducer gears are rotatably mounted on the secondary shaft and engaged with respective gears of the main shaft gears at different gear ratios corresponding to ranges of different speeds. A speed reducer synchronizer is interposed between the two speed reducer gears on the secondary shaft for fixing one of the speed reducer gears to the secondary shaft. A fixed gear on the secondary shaft is engaged with the end gear of the driving input shaft.
