I am experiencing dangerous shifting failures with my 2015 Ford F-150 equipped with the 6R80 automatic transmission. My truck intermittently fails to shift properly, holds onto gears too long, or refuses to shift into 6th gear. It also enters fail-safe mode, displaying a wrench icon on the dashboard. Restarting the vehicle temporarily resolves the issue, but it keeps coming back. The truck recently threw diagnostic trouble codes P0720 and P0722, which are related to the Output Shaft Speed (OSS) sensor, a known failure point in the 6R80 transmission lead frame. Ford previously recalled 2011-2013 F-150s (Recall #19V-075, Ford Recall 19S07) for this exact issue because it can cause a catastrophic downshift from 6th gear to 1st at highway speeds, leading to loss of control. However, 2015 models were not included in the recall, despite using the same transmission and lead frame. I am concerned that Fords recall did not go far enough and that my 2015 F-150 should be included due to the identical symptoms and part failure. This is a serious safety hazard, as a sudden downshift at highway speeds could cause loss of control, an accident, or even fatalities. I am requesting that the NHTSA investigate this issue and expand the recall to include 2015 F-150s with the same 6R80 transmission and defective lead frame.
