In one example a driveline may include a first and a second input shaft gear disposed on an input shaft. In one example, the first input shaft gear may selectively drivingly engage with the input shaft via a first clutch and the second input shaft gear may selectively drivingly engage with the input shaft via a second clutch. In another example, a first and a second counter shaft gear may be disposed on a countershaft and drivingly engage with the countershaft, wherein the first input shaft gear drivingly engages with the first countershaft gear and the second input shaft gear is drivingly engages with the second countershaft gear via an idler gear. ## Claims ### Claim 1 A driveline, comprising: a first input shaft gear and a second input shaft gear disposed on an input shaft, wherein the first input shaft gear is selectively drivingly engaged with the input shaft via a first clutch and the second input shaft gear is selectively drivingly engaged with the input shaft via a second clutch; a first countershaft gear and a second countershaft gear disposed on a countershaft and drivingly engaged with the countershaft; wherein the first input shaft gear is drivingly engaged with the first countershaft gear and the second input shaft gear is drivingly engaged with the second countershaft gear via an idler gear; and an output shaft and an output shaft gear disposed on and drivingly engaged with the output shaft, wherein the output shaft gear is in meshing engagement with the first countershaft gear, wherein the input shaft, the countershaft, a power take-off (PTO) gear train, and the output shaft are affixed within a plate at a surface of the plate that faces away from a backplate of a turbine portion of a torque converter, and wherein the plate is parallel with the backplate of the turbine portion of the torque converter, wherein the plate is coupled to the backplate of the turbine portion, and wherein the first input shaft gear is mounted to the surface of the plate. ### Claim 2 (depends on 1) The driveline according to claim 1, wherein the first input shaft gear is in meshing engagement with the first countershaft gear, the second input shaft gear is in meshing engagement with the idler gear, and the idler gear is in meshing engagement with the second countershaft gear. ### Claim 3 (depends on 1) The driveline according to claim 1, wherein the first clutch and the second clutch are disposed on and coaxial with the input shaft. ### Claim 4 (depends on 1) The driveline according to claim 1, wherein the first countershaft gear and the second countershaft gear are rigidly mounted on the countershaft. ### Claim 5 (depends on 1) The driveline according to claim 1, wherein the output shaft gear is rigidly mounted on the output shaft. ### Claim 6 (depends on 1) The driveline according to claim 1, further comprising an engine in driving engagement with the input shaft. ### Claim 7 (depends on 1) The driveline according to claim 1, wherein the torque converter comprises an impeller portion and the turbine portion, and wherein an engine is drivingly engaged with the impeller portion. ### Claim 8 (depends on 7) The driveline according to claim 7, wherein the PTO gear train is drivingly engaged or in mesh with the impeller portion. ### Claim 9 (depends on 1) The driveline according to claim 1, wherein the first clutch and/or the second clutch is a friction clutch, a dog clutch, or a synchronizer clutch. ### Claim 10 (depends on 1) The driveline according to claim 1, wherein the first clutch and the second clutch are multi-plate clutches. ### Claim 11 (depends on 1) The driveline according to claim 1, wherein the surface of the plate facing away from the backplate forms part of an exterior surface of the driveline. ### Claim 12 (depends on 1) The driveline according to claim 1, wherein the backplate comprises a plurality of through holes. ### Claim 13 (depends on 12) The driveline according to claim 12, wherein the plurality of through holes includes a first set of holes and a second set of holes at radially different positions. ### Claim 14 (depends on 13) The driveline according to claim 13, wherein the first set of holes is formed into extensions of the backplate, and wherein the second set of holes is formed into a rim of the backplate. ### Claim 15 (depends on 1) The driveline according to claim 1, wherein the first input shaft gear and the first countershaft gear are further positioned at the surface of the plate. ### Claim 16 (depends on 1) The driveline according to claim 1, wherein the plate is a different shape than the backplate. ### Claim 17 (depends on 16) The driveline according to claim 16, wherein the backplate is circular.
