“MY 2013 FORD EXPEDITION TRANSMISSION UNEXPECTEDLY DOWNSHIFTS TO A LOWER GEAR WITHOUT INPUT FROM THE DRIVER CAUSING THE VEHICLE TO SLOW DOWN SUDDENLY WITHOUT WARNING, OR THE TRANSMISSION DOES NOT SHIFT UP TO A HIGHER GEAR WHEN ACCELERATING”
“We were going down a road around 60 mph and with no warning or symptom the car downshifted from 6th to 1st gear. This caused the rear end to lock up causing the tires to squeal and spin the car around sideways in the road”
“The contact owns a 2013 Ford Expedition. The contact stated while driving 70 MPH, the check engine warning light illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the transmission molded leadframe”
