A method for reaching a neutral position N located between two end positions of a gearshift fork in a shift transmission in a motor vehicle from a starting position of the gearshift fork. The method allows finding the neutral position of the gearshift fork without a sensor determining the position of the gearshift fork or in the alternative in case such the sensor is defect.

The invention relates to a vehicle having a drive train, which comprises at least one first engine and a wheel, wherein a torque can be transmitted from the first engine to the wheel by the drive train, and wherein at least one first unit of the drive train is connected to an interface, by which rapid and simple replaceability of said unit is possible, wherein the interface is designed to be connected to a second unit, which is different from the first unit, wherein both units are designed to store electricity, to convert chemically bound energy into energy of rotation and/or to convert electricity into energy of rotation and/or to convert rotation energy of rotation into electricity.

A multiple ratio transmission having a main gear unit with at least three forward driving ratios and a single reverse drive ratio and a simple planetary gear unit in series with the main gear unit, the simple planetary gear unit being downshifted and the main gear unit being upshifted on an upshift from a first intermediate ratio to a higher intermediate ratio, the simple planetary gear unit being upshifted and the main gear unit being downshifted on a downshift from the higher intermediate ratio to the first intermediate ratio, the initiation of the inertia phase of the upshifting mean gear unit on an overall automatic transmission ratio upshift triggering the beginning of the release of a reaction element of said simple planetary gear unit upon downshifting of said simple planetary gear unit.
