The 10r80 10-speed automatic transmission and the gear-shift linkage module are defective, and the truck remains available for inspection. Our safety is constantly put at risk because the transmission exhibits an extremely violent, highly intermittent powertrain lunging jolt during deceleration and stopping. The impact is so severe that it sounds and feels like a loud gunshot firing right next to the cabin occupants. Furthermore, the transmission simultaneously exhibits severe throttle hesitation and gear-skipping. This causes the vehicle to drop gears and completely fail to move when attempting to accelerate at busy stoplights, trapping us as a sitting duck in active traffic. Earlier in our timeline, the technician improperly reassembled the shift linkage, which caused the multi-ton vehicle to refuse to engage in park and violently roll backward down a steep residential incline; an emergency parking brake deployment was required to prevent a catastrophic accident. The transmission defect was physically confirmed by baxter Ford of papillion, who verified scored, sticking fluid control valves inside the main control unit. Additionally, the hazard was officially confirmed by bbb auto line national arbitrator sharon katt (case frd2605350). The arbitrator officially signed a ruling certifying that our safety, use, and value concerns are completely valid, explicitly noting that the intermittent nature of this transmission failure does not minimize the extreme safety hazard. There were no warning lamps prior to the failure. The symptoms first appeared at ~49,000 miles. The dealer has since refused advanced diagnostics, executed an irrelevant radio reset instead, and willfully fabricated a fake service record on carfax on April 21, 2026, to force-close system safety alerts in their database.
The factory driver's side floor mat does not stay snapped in. This causes the floor mat to slide forward towards the pedals. This causes the floor mat to lodge underneath the accelerator pedal, which can cause an inability to accelerate. The fllor mat could also lodge undermeath the brake pedal, not allowing the full use of the brakes.
