Claim Text:
1. A method for operating an automatic transmission, the automatic transmission having a plurality of non-positive shifting elements and at least one positive shifting element, the method comprising: measuring an input speed of the automatic transmission and an output speed of the automatic transmission; and synchronizing a first positive shifting element of the at least one positive shifting element with: (1) a first process if the input speed of the automatic transmission is less than a criterion input speed at said step of measuring; (2) a second process if the input speed of the automatic transmission is greater than the criterion input speed at said step of measuring and the output speed of the automatic transmission is greater than a criterion output speed at said step of measuring; or (3) a third process if the input speed of the automatic transmission is greater than the criterion input speed at said step of measuring and the output speed of the automatic transmission is less than the criterion output speed at said step of measuring;
