1. A dual clutch transmission comprising:

  • a first input shaft supporting a first headset gear element;

    a second input shaft concentric with the first input shaft and supporting a second and a third headset gear element;

    a first mainshaft coaxial with the first input shaft and supporting a first pair of gear elements;

    a second mainshaft coaxial with the first mainshaft and supporting a second pair of gear elements;

    a countershaft offset from the first input shaft and supporting seven countershaft gear elements drivably connected to respective gear elements on the first and second input shafts and the first and second mainshafts thereby forming seven forward gear meshes for the transmission; and

    an output shaft coaxial with and connected to the second mainshaft for rotation therewith;

    wherein the seven forward gear meshes provide at least nine forward gear ratios for the transmission; and

    wherein the transmission is powershiftable between consecutive gear ratios of the at least nine gear ratios such that no torque interrupt occurs during sequential shifts.
