PCT No. PCT/EP97/06386 Sec. 371 Date May 6, 1999 Sec. 102(e) Date May 6, 1999 PCT Filed Nov. 15, 1997 PCT Pub. No. WO98/23884 PCT Pub. Date Jun. 4, 1998For an electro-hydraulically controlled automatic transmission (2) in which shifts are performed by overlapping, a method is proposed for increasing the spontaneity, in which a variable hold time is introduced for a disengaging clutch. This variable hold time is a function of the rotational speed differential of a transmission input speed (nT) and the temperature of the hydraulic fluid ( THETA ).
