The automated, sequential six-gear transmission developedfrom the classical six-gear manual transmission is controlled by the enginemanagement. With the help of a hydraulic piston, 2 gears can be shifted on eachshift level. To change to another shift level, a gate sleeve, which had beenable to rotate loosely up to then, is arrested by a second hydraulic piston. Inthis way, the old gear is firstly removed and then the selector shaft turnedonto a different shift level by a pin in the arrested gate sleeve when theinlet selector shaft is displaced by the first hydraulic piston. Now, shiftinginto the next gear is possible. The installation of a gearshift rod with abutton and a mechanical clamping lever means that all the gears can be shiftedand the function of the hydraulic controls demonstrated.
