While driving the vehicle going approximately 35 mph in heavy traffic the vehicle shifted to neutral without driver input as evident by +8000 rpms (bottomed out) and swift deceleration. No warning lights or indicators. No response when driver input to acceleration pedal. Vehicle would not shift into gear.

After waiting in neutral on the side for a minute accelerator response returned. hard and delayed shifting remained. Vehicle is currently being serviced by a ford dealer in Florida who relays no warning or trouble codes found - but recommended a transmission rebuild reference black fluid w/o leaks. Fluid was initially a quart and a half low. Transmission has an extended warranty and is getting replaced. 10r80 10 spd transmission with the EXACT same issue for the recent recall of a different year/ transmission model # by ford. Coincidence- I think not.

f150 EQUIPED WITH 4r80 10 SPEED TRANSMISSION. Starting several months ago, the vehicle started experiencing up shifts with hesitation during upshift, typically the mid gears. Starting from a stop, the shift from 1st to 3rd is very harsh and stutters. Condition has progressively gotten worse. While upshifting, I am now experiencing more exaggerated pausing/delays during mid gear upshifts. While entering a freeway, accelerated to merge with traffic and the transmission downshifted and there was an approximately 2 second delay in the shift which caused the vehicle to bog down substantially, nearly causing a following vehicle to impact my vehicle.

My gears shift hard when slowing down or when letting go of the gas pedal. The infotainment center blacks out. I took it in to Ford Dealership and was told the transmission needed to be replaced. I don’t drive fast nor abuse my truck. I don’t use my truck for construction; I simply drive to work and home. I have 67K miles and bought the truck in 2020, brand new. It’s very concerning that at 67K the transmission needs replacement. The cost for replacing the transmission is $8,000.00 dollars.

On the afternoon of [XXX], my son and his fiancé were driving home from college (Lamar University) when my sons 2020 Ford F-150 suddenly downshifted from 10th gear to 1st gear. This sudden unexpected downshift through them both violently forward in the truck and almost caused them to be rear ended by an 18-Wheeler. They immediately pulled off to the side of the Interstate ([XXX]) to gather their thoughts and inspect the truck. My son notified me of what had just happened and that he received a service engine warning on the trucks instrument cluster along with a notification on his cell phone of a Powertrain Malfunction. I suggested he try turning the truck off and restarting it to see if it would resolve the issue. He resumed driving home and experienced the same unexpected sudden down shifting from 10th gear to 1st gear multiple times as they continued their drive home. Fortunately, he was able to limp his truck back into town and immediately took it to Cook Ford in Texas City where we had purchased the truck. I met them at the dealership and my son reported the problem they had experienced on their drive home to the Cook Ford Service person and we left the truck with them to be diagnosed. On Wednesday March 26th 2025, Cook Ford called to inform my son and informed him that he needed a new transmission and that both his catalytic converters needed to be replaced for a cost of approximately $11,500. He asked them if these items were covered under warranty and they acknowledged an error in their quote and that the catalytic converters would be covered, but not the transmission. During the conversation the Ford Service person did acknowledge knowing of issues with the 10 speed transmission (10R80) but said there were no current recalls, nor were there any Ford Customer Satisfaction Programs for the trucks transmission. We are now waiting for a response back from Cook Ford with an updated and formal breakdown of costs for the trucks needed repairs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A
