   Our 2017 Ford Expedition, has been diagnosed with a failure involving the molded lead frame/transmission sensor assembly in its 6R80 transmission. We were advised that the failure can cause the transmission to unexpectedly downshift at highway speed, resulting in sudden deceleration and possible loss of control. Ford has recalled 2015–2017 F-150 vehicles equipped with the 6R80 for a substantially similar unintended-downshift condition, but Ford states that our Expedition is…

   Sudden and severe downshifts occurred at roadway and highway speeds resulting in sudden speed decrease. Also revving and loss of power occurred. Problem codes P0706 & P0707 were logged which point directly to the Transmission Range Sensor (TRS), which is integrated into the molded lead frame. This sudden and uncontrolled loss of speed caused significant danger to vehicles, ocupants, and other vehicles.

   My 2017 Ford Expedition is currently at an authorized dealership (Arlington Heights Ford, IL) for a failed transmission lead frame (DTCs P0706, P0707, P1702), which causes intermittent loss of gear engagement and sudden shift issues.

   While towing our RV trailer, we received a wrench light and the vehicle when into limp mode. When we tried to slow down and take the next exit on the interstate, the transmission tried to shift from 6th gear to 1st gear, causing the rear tires to screech and slow the vehicle dramatically. This could have caused a rear collision due to the abrupt slowing of the vehicle. The problem could only be reproduced when towing a trailer for an hour or more, so the problem was not…

    We were driving on the highway and suddenly lost all power. Vehicle downshifted so hard I thought someone had hit us. Then it was back to normal, driving fine. But now we had no speedometer and the check engine and wrench light were on. My wife said she had felt something like that before but it was minor and at a lower speed. It had never resulted in a check engine light or loss of speedometer. I told her to exit the highway. She was shaking like crazy because she thought…
