A multiple speed power transmission comprises: an input; an output; first and second input shafts releasably coupled to the input by first and second friction clutches, respectively; a countershaft disposed parallel to the first and second input shafts; an output pinion fixed to the countershaft; an output ring gear fixed to the output and meshing with the output pinion; an intermediate shaft disposed coaxially with the countershaft; a first input pinion fixed to the first input shaft and meshing with a first gear fixed to the intermediate shaft; a second input pinion fixed to the second input shaft; a second gear disposed coaxially with the intermediate shaft; an idler gear meshing with the second input pinion and the second gear; a first coupler for releasably coupling the first countershaft to the intermediate shaft; and a second coupler for releasably coupling the intermediate shaft to the second gear.
