Abstract
A transmission includes a main shaft having two or more main shaft clutches that couple gears to at least one countershaft, and an automated manual transmission coupled to the main shaft via the at least one countershaft. The automated manual transmission includes a front input shaft coupled directly to a main clutch and having a first clutch coupleable to the at least one countershaft, and a rear input shaft coupled to the front input shaft and having a second clutch coupleable to the at least one countershaft. The automated manual transmission is operable to selectively engage the first clutch and the second clutch.

A method of manufacturing a transmission, comprising:
- providing a main shaft having two or more main shaft clutches that couple gears to two countershafts;
- and
- providing an automated manual transmission using steps that include:
- a. coupling a front input shaft directly to a main clutch, the front input shaft having a first clutch coupleable to the two countershafts via a first splitter section gear;
- and
- b. torsionally coupling a rear input shaft directly to the front input shaft, the rear input shaft having a second clutch coupleable to the two countershafts via a second splitter section gear and a third splitter section gear;
- wherein the automated manual transmission splitter section is operable to selectively engage the first clutch and the second clutch.
