Some 2012-2013 Ford Expedition vehicles equipped with a 6R80 transmission and built on or before 4/8/2013 may exhibit a transmission engagement in 5th gear when starting from a stop.
The wrench icon indicator and/or the seat belt minder may be illuminated, the speedometer reads zero and the odometer displays dashes while driving. Symptoms may clear after an ignition key cycle. DTCs P0720 and P0722 may or may not be stored in the PCM.
