Abstract
The present subject matter provides a method for operating an automatic transmission in a limp mode. The method includes actuating a first non-positive shifting element to an engaged configuration and actuating a second non-positive shifting element to the engaged configuration. A positive shifting element is substantially synchronized after actuating the second non-positive shifting element. The method also includes commanding the positive shifting element to actuate from a disengaged configuration to the engaged configuration.
