Vehicles Affected: Approximately 184,000 model-year 2011-12 Ford F-150 pickup trucks, model-year 2012 Expedition SUVs and Mustang sports cars, and model-year 2012 Lincoln Navigator SUVs equipped with the 6R80 transmission
The Problem: A problem with the output speed sensor on the vehicle’s transmission lead frame could cause the transmission controls to force a temporary downshift into 1st gear. Depending on the speed of the vehicle at the time of the downshift, the driver could experience an abrupt speed reduction that could cause the rear tires to slide or lock up, resulting in loss of vehicle control and increasing the risk of a crash. Ford is aware of three reported accidents and no injuries related to this condition.
