Methods for automated calibration and adaption of a gearshift controller (39) are disclosed. In one aspect, the method automates calibration a gearshift controller (39) for controlling a sequence of gearshifts in either a stepped automatic transmission equipped with at least one speed sensor mounted on a dynamometer (42) or an automotive vehicle mounted on a dynamometer (42), where the dynamometer (42) is electronically controlled by a dynamometer controller (43). Each gearshift in the sequence includes a first phase, a second phase, . . . and an Nth phase. The gearshift controller (39) includes (initial values of) a first phase control parameters set, a second phase control parameters set, . . . and an Nth phase control parameters set for each gearshift in the sequence that are updated using a first phase learning controller, a second phase learning controller, . . . and an N*11 phase learning controller respectively.
