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 clutch assembly including a sealed clutch and a spacer. The clutch is connected to the spacer and the spacer is connectable to a flywheel along a common axis and the spacer facilitates connection of the clutch to the flywheel in at least two different axially spaced positions. A connection ring can connect the spacer connection to flywheel.

A method for producing friction discs for a, in particular radial, dual clutch, includes the following steps: providing a first disc ring with a first inner diameter, providing a second disc ring with a second outer diameter, wherein the second outer diameter is smaller than the first inner diameter, and processing the first disc ring and the second disc ring in a tool for producing the friction discs. The second disc ring is arranged within the first disc ring, and the second and the first disc rings are processed in the tool together.

Transmission system for a vehicle having an input arranged for connection to a drive source, and an output arranged for connection to a load. The transmission includes a transmission. The transmission includes first input shaft, a first output shaft connected to the output, and a first speed transforming gear connecting the first input shaft and the first output shaft, and a second input shaft, a second output shaft connected to the output, and a second speed transforming gear connecting the second input shaft and the second output shaft. The transmission includes a first coupling member, arranged for coupling the input to the first input shaft at a first speed ratio and a second coupling member, arranged for coupling the input to the second input shaft at a second speed ratio.
