Summary
Some 2018-2021 Expedition/Navigator and 2020-2021 Explorer/Aviator vehicles equipped with a 10R80/10R80 MHT or 10R60 may exhibit a momentary transmission neutral-out condition while in drive. Vehicle may also have diagnostic trouble code (DTC) P07E6 and/or P07E4 stored in the powertrain control module (PCM) or transmission control module (TCM) and/or a possible audible noise. This may be due to a leak in the park valve circuit. To correct the condition, follow the Service Procedure to inspect the park system hardware for wear or damage and replace the valve body separator plate with an improved valve body separator plate.
