FORD recall on MUSTANG, F150, EXPEDITION, and NAVIGATOR models

Certain vehicles equipped with a 6-speed automatic transmission may experience an intermittent loss of the Transmission Output-shaft Speed Sensor (OSS) signal to the Power Control Module. This could potentially cause an unintended downshift into first gear, which depending on vehicle speed at the time of the downshift, may cause the rear tires to slide or lock up until the vehicle slows. This may result in a loss of vehicle control without warning, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will reprogram the Powertrain Control Module with updated software.
