| 主权项 | 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: commanding a first one of the at least one positive shifting element to actuate from an engaged configuration to a disengaged configuration; determining a position of the first one of the at least one positive shifting element during said step of commanding; and opening at least one non-positive shifting element of the plurality of non-positive shifting elements if the position of the first one of the at least one positive shifting element does not reach an open position during said step of determining. | ||
