    摘要: A method and apparatus for automatically shifting the individual speeds of a change-speed gear, particularly for motor vehicles, by means of force-locking shifting elements and by the use of a hydrodynamic unit, such as a torque converter or hydrodynamic coupling, whose slippage condition is increased during the change in transmission ratio by engageable means, in which the pressure space of the shifting element for the new speed is filled with a pressure medium while the shifting element for the pre-existing speed remains under hydraulic shifting pressure and the slippage condition in the hydrodynamic unit is maintained for a certain length of time; only after the filling of the pressure space of the shifting element for the new speed and with substantial simultaneous disengagement of the pre-existing speed, the slippage condition in the hydrodynamic unit is then increased; in the event a by-pass clutch is provided for the hydrodynamic unit, the by-pass clutch remains engaged until the pressure space of the servo-shifting element for the new speed is completely filled, at which time the by-pass clutch is disengaged with simultaneous disengagement of the pre-existing speed.
