A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing is operationally coupled to the shift actuator and a linear clutch actuator. The linear clutch actuator is a self-adjusting actuator, and the transmission includes a self-adjusting clutch.

A drive system is provided for coupling a clutch assembly with a pump assembly that provides fluid power to cool, lubricate and control the operation of the clutch. The drive system comprises a drive coupling rotatably supported on an input shaft by a plurality of bearing members. The bearing members permit the drive coupling to rotate independent of the rotation of the input shaft. The drive coupling is provided with at least two splined surfaces for engaging a corresponding splined surface on both the clutch assembly and the pump. The drive system counteracts radial loads generated within the pump and moment loads generated at the splined connections to prevent premature wear or damage to the pumping elements and mating components.
