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 controls the shift actuator with actuating and opposing pulses, and 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 gearbox (1) for agricultural and industrial motor vehicles comprises an input shaft (2) and an output shaft (3), a first clutch (12) and a second clutch (13) arranged in a position between the first and second transmission shafts (16, 17), the first and second transmission shafts both being hollow. The gearbox further comprises a first intermediate shaft (20) and a second intermediate shaft (21), the first intermediate shaft extending coaxially inside the second intermediate shaft. A first engaging device (22) is capable of selectively connecting the first intermediate shaft to the output shaft, a second engaging device (23) is capable of selectively connecting the second intermediate shaft to the output shaft and a third engaging device (24) alternately connects the second intermediate shaft to the first intermediate shaft or to the output shaft. The first engaging device and second engaging device are coaxial with the output shaft. The third engaging device is coaxial with the first and second intermediate shafts and is interposed in an axial position between the first and second engaging devices.
