A method is provided for configuring different numbers of gearshift variants in a stepped powershift transmission for an agricultural working machine. The method includes providing a transmission unit, a front-mounted range unit, a gear reduction unit, a rear-mounted range unit, a housing, a drive shaft, a lay shaft an output shaft, and a hydraulic control arrangement. The same transmission unit is used for all the numbers of gearshift variants while an identical spatial orientation of the shafts is maintained for all the numbers of gearshift variants. The method further includes adapting exclusively the gearshift variants by varying the front-mounted range unit or the rear-mounted range unit.

A transmission includes a drive element, a first output element, a primary transmission unit, a reversing unit, and an intermediate gearbox. At least three of the at least seven shifting elements of the primary transmission unit, at least one of the at least two shifting elements of the reversing unit, and at least one of the at least two shifting elements of the intermediate gearbox are activatable in combinations of at least five shifting elements so as to establish at least eighteen forward gears between the drive element and the first output element.

An automated manual transmission may include an input shaft selectively provided with torque from an engine through a clutch; an output shaft disposed in parallel with the input shaft; a shifting device including a plurality of gear pairs, which have different gear ratios and are engaged with each other on the input shaft and the output shaft, and selecting at least a gear pair out of the plurality of gear pairs, by using a coupling member; wherein the at least a gear pair corresponds to a speed of a vehicle a motor shaft connected to a motor and provided with torque from the motor; and clutch devices disposed between the motor shaft and the input shaft to transmit torque in a first direction thereof and between the motor shaft and the output shaft to transmit torque in a second direction thereof.

A control apparatus for a vehicular power transmitting system includes a drive mode setting portion configured to select a first reverse drive mode of the vehicle to be established with an engaging action of the first coupling element, and a required vehicle drive force determining portion configured to determine whether a degree of operation of an accelerator pedal of the vehicle during reverse driving of the vehicle is higher than a predetermined threshold value. The drive mode setting portion selects the first reverse drive mode when the required vehicle drive force determining portion has determined that the degree of operation of the accelerator pedal during the reverse driving of the vehicle is higher than the predetermined threshold value.

A transmission includes a drive element, a first output element, a primary transmission unit, a reversing unit, and an intermediate gearbox. At least three of the at least eight shifting elements of the primary transmission unit, at least one of the at least two shifting elements of the reversing unit, and at least one of the at least two shifting elements of the intermediate gearbox are activatable in combinations of at least five shifting elements so as to establish at least twenty-eight forward gears between the drive element and the first output element.

A transmission includes a drive element, a first output element, a primary transmission unit, a reversing unit, and an intermediate gearbox. At least two of the at least nine shifting elements of the primary transmission unit, at least one of the at least two shifting elements of the reversing unit, and at least one of the at least two shifting elements of the intermediate gearbox are activatable in combinations of at least four shifting elements so as to establish at least twenty-eight forward gears between the drive element and the first output element.
