Abstract
Gear-changing quality of a motor vehicle having an automatic transmission in which filling pressure adaptation processes are carried out by an electronic control device by predefined activation of an oil pump and selected hydraulic switching elements is improved by inclusion of a minimum time margin between the individual adaptation processes predefined by the control device such that parallel adaptation processes are prevented.
