Abstract
A method for operating an automatic transmission is provided. The method includes synchronizing a positive shifting element of the automatic transmission, braking the automatic transmission with a first non-positive shifting element of the automatic transmission, establishing a position of the positive shifting element, and increasing a pressure of fluid supplied to a second non-positive shifting element of the automatic transmission if the position of the positive shifting element is an intermediate position.
