1. An automated truck transmission, comprising:
a transmission housing;
an input shaft configured to couple to a prime mover for receiving torque therefrom, the input shaft having a first gear and a second gear rotatably coupleable to the input shaft;
a main shaft coaxial with the input shaft and having the second gear, a third gear and a fourth gear rotatably mounted thereon, each of the second gear, the third gear and the fourth gear being rotatably coupleable to the main shaft;
a countershaft having a plurality of countershaft gears mounted thereon and each in meshing engagement with a respective one of the first gear, the second gear, the third gear and the fourth gear;
an output shaft selectively providing a torque output to a driveline of the transmission;
a shift actuator structured to engage a plurality of shift forks to selectively couple the input shaft to the main shaft by rotatably coupling a select one of the first gear and the second gear to the input shaft and a select one of the second gear, the third gear and the fourth gear to the main shaft, wherein the shift actuator is mounted on an exterior wall of the transmission housing, and wherein the countershaft and the main shaft are at least partially positioned within the transmission housing;
further comprising an integrated actuator housing, wherein the shift actuator is operationally coupled to the integrated actuator housing, and
a clutch actuator housing mounted directly to the integrated actuator housing.
