Abstract
A method is provided for shifting a transmission, more particularly an automatic planetary transmission, having multiple non-positive shift elements and at least one positive shift element. The transmission can assume particular transmission states according to current shifting states of the shift elements, each transmission state having a particular transmission ratio between a transmission input and a transmission output. At least two transmission states have identical transmission ratios. To shift into a first of the at least two transmission states that have identical transmission ratios, only non-positive shift elements are engaged. By contrast, to shift into a second of the at least two transmission states that have identical transmission ratios, at least one positive shift element is engaged. At least for shift operations involving shifting to the identical transmission ratio from a current transmission state that has a transmission ratio other than the identical transmission ratio, the transmission is shifted first into the first transmission state and then into the second transmission state.
