A shift control method of an automatic transmission that controls a shift from an nth shift speed, achieved by engagement of first and second friction elements, to an th shift speed, achieved by engagement of third and fourth friction elements. 25% by weight, heating to an austenitizing temperature and subsequent quenching, and applying a basic coating comprising zinc flakes non-electrolytically onto the hardened low-alloy steel washer. The filter for drying the air and the odor filter are, preferably, combined in a filter cassette that is disposed on the filter housing such that it can be changedreplaced. The links connecting the cylindrical rings are non-linear. , the position information is read by the cantilever corresponding to the position control area and, based on the position information, the positioning control or moving control of all the other cantilevers is performed.
