A drive assembly for a work vehicle includes a housing arrangement, a drive shaft rotatable in first and second clock directions, and a two-stage planetary gear set coupled to the drive shaft. The gear set includes, or is coupled to, an output element. First and second clutch arrangements are configured to selectively engage the gear set to effect first and second gear ratios, respectively. A step ratio from the first gear ratio and the second gear ratio is 3:1. At least one first actuator and at least one second actuator are configured to effect movement of the first and second clutch arrangements, respectively, to selectively engage the gear set. The drive shaft and the output element rotate in a same clock direction with the first clutch arrangement engaged with the gear set, and in opposite clock directions with the second clutch arrangement engaged with the gear set.

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 includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

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. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.
