Zusammenfassung:	PCT No. PCT/EP92/01136 Sec. 371 Date Jun. 22, 1994 Sec. 102(e) Date Jun. 22, 1994 PCT Filed May 21, 1992 PCT Pub. No. WO93/00624 PCT Pub. Date Jan. 7, 1993A method for controlling preferably an electro-hydraulic automatic transmission of a motor vehicle fitted with a combustion engine provides a gradual kick-down while braking. In particular the kick-down is performed when, in the course of approaching a bend, a condition is activated, which prevents upshifting. The upshift prevention is initiated when the accelerator pedal is released quickly during shearing action. The upshift prevention stops if after an interval, upon detection of tensile action, the vehicle does drive round a bend. The upshift prevention is followed by a gradual adaptation of the gear level to the shift parameter.
