Abstract
A dual clutch transmission is provided with first and second coaxial input shafts, at least one mainshaft, and an output shaft that are coaxial with one another. The transmission has a countershaft offset from the first input shaft that supports seven countershaft gear elements drivably connected to respective gear elements on the first and second input shafts and the at least one mainshaft thereby forming seven forward gear meshes for the transmission. The seven forward gear meshes provide at least nine forward gear ratios for the transmission. The transmission is powershiftable between consecutive gear ratios of the at least nine gear ratios such that no torque interrupt occurs during sequential shifts.
