shaft; first and second intermediate shafts disposed in parallel with the input shaft; a first-speed driving gear, a second-speed driving gear, a third-speed driving gear, a fourth-speed driving gear, a fifth driving gear and a six-speed driving gear disposed on the input shaft; a reverse-only driving gear, a first-speed driven gear and a second-speed driven gear disposed on the first intermediate shaft; a third-speed driven gear, a fourth-speed driven gear, a fifth-speed driven gear and a sixth-speed driven gear disposed on the second intermediate shaft; a thirdxe2x80x94fourth-speed synchronizer disposed on the first input shaft for selectively engaging and disengaging the third-speed driving gear or the fourth-speed driving gear with said input shaft; a synchronizer for reverse gear disposed on the first intermediate shaft or reverse-only driving gear forcausing the first-speed driven gear and the reverse-only driving gear to engage and disengage; a firstxe2x80x94second-speed synchronizer disposed on the first intermediate shaft for selectively engaging and disengaging the first-speed driven gear or the second-speed driven gear with the first shaft; and a fifthxe2x80x94sixth-speed synchronizer disposed on the second intermediate shaft for selectively engaging and disengaging the fifth-speed driven gear or the sixth-speed driven gear with the second intermediate gear; wherein a reverse-gear stage is constructed by the first-speed driving gear, the first-speed driven gear, the reverse-only driving gear, the third-speed driven gear and the synchronizer for reverse gear.
In a preferred embodiment of the present invention, the reverse-gear stage of the manual transmission includes a first-speed driving gear, a first-speed driven gear and a third-speed driven gear.
