Abstract: A vehicle drive-train includes a drive-motor having an output shaft and a transmission having an input shaft, an output shaft, a plurality of discrete forward gear ratios and a corresponding plurality of synchronizers. Each of the synchronizers is configured to mechanically synchronize rotation of the drive-motor output shaft with the transmission output shaft according to a value of a selected gear ratio, during shifting of the transmission to the selected gear ratio. The output shaft of the drive-motor and the input shaft of the transmission are coupled together such that, during normal operation of the drive-train, rotation of the output shaft of the drive-motor results in a proportionate and uninterrupted rotation of the input shaft of the transmission.
