Ford Outdoes General Motors With Latest Transmission Investigation

The U.S. National Highway Traffic Safety Administration (NHTSA) has launched a preliminary investigation into nearly 1.3 million Ford F-150 pickup trucks following reports of unexpected transmission downshifts that may cause temporary rear wheel lock-up.


Key Points

  • NHTSA has opened a preliminary evaluation into nearly 1.3 million Ford F-150 trucks from model years 2015 to 2017 after receiving 138 consumer complaints
  • Drivers report unexpected downshifts to lower gears at highway speeds, sometimes accompanied by temporary rear wheel lock-up, sudden deceleration, and loss of control
  • GM previously issued a recall related to similar transmission problems

This action follows 138 consumer complaints alleging unexpected downshifts to lower gears while driving at highway speeds, leading to sudden deceleration. In certain instances, drivers reported that the rear wheels temporarily locked, causing skidding or loss of vehicle control.


This isn't the first time Ford's F-150 has faced scrutiny over transmission issues. In August 2024, Ford recalled nearly 668,000 F-150 models due to similar concerns of unexpected downshifting into first gear, which could result in loss of control or rear-wheel lockup. The problem was attributed to a loss of signal between the transmission sensor and the powertrain control computer. ​

Complicating matters, the 2015–2017 F-150s under investigation are equipped with a six-speed automatic transmission. Notably, Ford and General Motors co-developed a 10-speed automatic transmission introduced in later F-150 models starting in 2017.


This 10-speed transmission has been the subject of multiple class-action lawsuits alleging issues such as harsh and erratic shifting, which can cause jerking, lunging, and hesitation between gears. ​ General Motors has been forced to recall 500,000 vehicles equipped with the jointly developed transmission. The issues with the 10-speed are similar to the rear-wheel lockup issues with Ford's now-recalled 6-speed automatic.


According to Ford, GM's issue is in relation to an issue with the latch balls, which are used to engage gears, these are seeing wear leading to unexpected downshifting. Ford says the 6-speed does not use latch balls.


Depending on NHTSA's findings, this could lead to a recall affecting a substantial number of vehicles. Owners are advised to stay informed about the investigation's progress and to report any related issues to NHTSA.
