Abstract
A method of shifting an automatic transmission of a motor vehicle having a hydrodynamic converter (). The method comprising the steps of detecting a presence of predetermined stopping conditions; determining that a driver of the motor vehicle intends to cause the motor vehicle to change from a driving state to a stopped state, based on the presence of one of the predetermined stopping conditions; and automatically shifting the automatic transmission () into a standby mode, before the driving state has concluded. The shifting into the standby mode typically occurs when a rotational speed of the hydrodynamic converter () decreases to less than a rotational speed () of a motor and the retarder apparatus (), of the automatic transmission, is disengaged no later than a time by which shifting into the standby mode occurs.
