1. A method for adapting shifts to be carried out in a transmission of a motor vehicle, wherein the shifts are triggered and controlled by a transmission control unit, the method comprising:

  • recording by a measuring instrument an actual value corresponding to an acceleration of the motor vehicle, the measuring instrument having a sampling rate selected such that the measuring instrument provides the actual value for each of a plurality of consecutive shift stages for each shift, the plurality of consecutive shift stages including a load reduction stage, a gear disengaging stage, a neutral stage, a gear engaging stage and a load buildup stage;

    with the transmission control unit, comparing the recorded actual value for each respective shift stage to a target value for each respective shift stage; and

    as a function of a deviation in the individual shift stages between the actual value and the target value, adapting the respective shift stages with the transmission control unit for subsequent shifts of the transmission, the deviation between the particular actual value and the particular target value being determined for all of the consecutive shift stages.
