My 2014 GC had the same error after an update by the dealer.
2014 Jeep Grand Cherokee Overland 3.6L 4x4; Quadra-Lift II; Off-Road Adventure II; Advanced Technology Group; Vesuvio Indigo Blue interior; white exterior; engine block heater; CD Player. Built April 2013. As of June 24, 2015, the Jeep has been driven about 43,000 miles (70 000 km). The transmission failed at 41,000 miles (65 000 km). A Jeep dealer under warranty replaced the transmission's valve body assembly. At 43,000 miles (70 000 km) the valve body assembly failed for a second time.
