Abstract:
A method for operating an automatic transmission is provided. The method includes commanding a positive shifting element to actuate to a disengaged configuration or an engaged configuration and opening at least one non-positive shifting element if the positive shifting element does not properly actuate. Opening the at least one non-positive shifting element may terminate power flow from the automatic transmission in order to protect the automatic transmission.
