A transmission apparatus for a vehicle includes an input shaft and an output shaft. The input shaft receives power from an engine of the vehicle. One of three gear pairs having different gear ratios operationally connects the input shaft to the output shaft to transfer the engine power to the output shaft. Synchronizers are used to select which of the three gear pairs operationally connects the input and output shafts. The transmission apparatus also includes a differential for transferring power to wheels of the vehicle. One of two final gear pairs having different gear ratios operationally connect the output shaft to the differential. Another synchronizer is used to select which of the two final gear pairs operationally connects the output power shaft to the differential. In this manner, the transmission apparatus can provide six forward speeds, and through the provision of a reverse gear unit, the transmission apparatus can also provide two reverse speeds. Accordingly, the transmission apparatus is compact, light weight, and improves overall fuel efficiency and power performance. |
