摘要： A method for operating a transmission of a vehicle, where the transmission couples a drive machine of the vehicle to a driven wheel of the vehicle and has different rotational speed transmission ratios. The method determines that a special load situation prevails or will prevail at the driven wheel of the vehicle. The method determines a shift time or a shift vehicle position, at which a load on the drive machine is less than or equal to a load threshold value. The method adapts the rotational speed transmission ratio of the transmission for the special load situation at the shift time or at the shift vehicle position.
