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 structure includes a transmission axle rotatably mounted at a center of a housing. The transmission axle includes a sun gear mounted thereon. An internally-toothed ring track is fixed to an inner circumference of the housing. A planetary gear set is arranged between the sun gear and the internally-toothed ring track. The planetary gear set includes a plurality of stepped planetary gears arranged around the sun gear for self-spinning and orbiting around the sun gear. Each stepped planetary gear includes a first toothed portion meshing with both the sun gear and the internally-toothed ring track and a second toothed portion rotatable in unison with the first toothed portion. An output member is fit over the planetary gear set and includes an inner circumference formed with an internal toothed circumference meshing with the second toothed portion of each stepped planetary gear.
