摘要： The invention relates to a method for controlling a two-step gear shift in a transmission (100, 200, 300, 400, 500). The transmission comprises a plurality of shift elements (138, 140, 142, 144, 146, 148, 150) engageable in combinations to obtain a plurality of gear stages to obtain a set of main gears, defining at least a main gear A, main gear B, main gear C and main gear D, each one of the main gears having a corresponding gear ratio, said main gears B and C further defining a pair of consecutive main gears, and said main gears A and D defining a pair of adjacent surrounding main gears, and further to obtain at least one auxiliary gear I positioned intermediate said pair of consecutive main gears B and C, said intermediate auxiliary gear I having a gear ratio being intermediate the gear ratios of said pair of consecutive main gears B and C. The method comprises the steps of, when selecting one of said main gears A and D of the adjacent surrounding pair of main gears, evaluating a switching from a first gear shifting mode (M1) to a second gear shifting mode (M2) by determining if a first predetermined vehicle condition is fulfilled, if said first predetermined vehicle condition is fulfilled, switching from said first gear shifting mode (M1) to said second gear shifting mode (M2), and performing a two-step gear shift from one of said main gears A and D of said adjacent surrounding pair of main gears to said intermediate auxiliary gear I.
