The transmission shifts so poorly I've almost been in several car accidents trying to merge highways or merge round-A-bouts. It shifts very hard on down shifts but also lacks any acceleration at times which is dangerous.

- Westfield, IN, USA

Stalls while merging with traffic. Then rpms raise and truck slams violently into gear. Extremely unsafe! numerous complaints to Ford. To no avail. Please help!

- Wexford, PA, USA

Put vehicle in park and exited vehicle to open a gate. Despite being in park, vehicle rolled back and crashed. Vehicle still showed being in park when retrieved. Total loss of truck. Contacted Ford with no resolution.

Vehicle will some times hesitate during acceleration and transmission will slip - engine rpms will rise to about 2000 and then transmission will engage with a heavy clunk in the drive train. This issues has happened when engine is cold and at normal operating temp. The vehicle currently has 9000 miles on the odometer and has happened five(5) times already. Took to local dealer and they are unable to tel me what is wrong

- Bridgeport, CT, USA

Hard drop in gear on start up. Intermittent long delays from drive to reverse or reverse to drive. Hard gear grab in 3rd and 6th regardless of speed or load. Highway speeds when slowing the transmission hits hard when going down into 6th. On city streets both up and down shift associated with 3rd gear are hard. The clunk is enough to shake the truck.

Vehicle moving while motor not running, indicator shows park.almost acts as if it were in neutral. Truck has 9100 miles. In late October, I leaned against truck while it was in garage and rolled backwards about 5-6'. I have opened a claim with Ford, have not heard anything back from their claims department. Claim # cas-24658090-K6M8T6. I have tried contacting them with multiple attempts. Only 1 of those attempts got me to that claim number. Every time I call now, they state that my case has not been assigned to an agent yet, even after 2 weeks.

I believe there is a major problem with the transmission. Vehicle frequently makes a loud bang when started. The vehicle shudders and I feel a thud in the wheel well. It's like the clutch is failing or something? shifting gears extremely rough to the point where you're jerked around. Sometimes, to get into gear, I have to turn the truck off and re-start. Sometimes there is no power when trying to accelerate (or the truck is out of gear) from a stop which is extremely dangerous when cars are behind you or trying to accelerate merging onto the freeway. Sometimes the vehicle simply drops out of gear and 'd" (drive) is not an option. This has also happened on the freeway. I've read about a lot of owner comments that are identical to mine. Reading all these issues completely agree, this issue is extremely dangerous!

The transmission will twist the driveshaft at startup, stationary, and cause the rear end to pop very loudly. I've shown Ford engineering a video of it, I was told that it was normal. I've never heard of a vehicle doing this before. There is a rattling sound on deceleration, loudest when the engine is cold and lessons or maybe even goes away after warmed up. The engine was replaced earlier this year because of an oil consumption issue. The truck has memory power driver's seat and power mirrors that should go into place depending on the key fob that it detects. Randomly both side mirrors will start moving and popping before going back into position. This always occurs before the vehicle is started. I've noticed that it is usually when it detects the key fob or when I use the fob for some function. The seat randomly doesn't go into the memory position at startup.

Transmission was rebuilt by dealership due to transmission issues and updated with newest release Ford software update. After 2000 miles vehicle makes a hard shirt/clunking noise when down shifting from 5th to 4th gear and when driving slow has issue shifting from 1st to 2nd gear. Lots of transmission noise with this vehicle. This has been happening a lot and is not specific to any particular time such if vehicle is cold or warm.

The new 10 speed transmission gear hunts. While the vehicle is in motion (city street or highway) decelerating with the break and re-accelerating causes the transmission to gear hunt which can sometimes cause acceleration lag, and rarely causes the entire vehicle to jolt (simulating a fender bender feel). This has only happened so far while going about 30-40 mph while driving straight. I have not gone to Ford with this issue yet as there are other concerning issues with this vehicle. Also, the other customers that have reported to Ford were told this is normal. This concerns me as the other issues I have had resulted in the same answer. To add to this issue I'm not sure this qualifies as the same issue but also while switching between reverse/drive/park there can at times be a large jolt. This has happened on both flat surfaces and on slight hills. As a note the break will be fully applied and the vehicle will be at a dead stop before I make any changes in the transmission function. Thank you for your time.

On initial take off, when the truck shifts through 1st and 6th gears it seems like the engine slows to the point that I have no power and then shifts. It also feels like the transmission slips. Have been told this is normal, but it is certainly a safety concern for merging into traffic because I can't get up to speed fast enough to avoid an accident. Ford needs to address this issue because it happens on most of their ecoboost engines and the 10 speed transmission combined. This truck has the 2.7L ecoboost engine.

Transmission shifts very harshly from 1st to 3rd on takeoff. It will also clunk and jerk at times shifting from drive to reverse. Driving down highway with cruise on it will rev up from 1400 RPM to 2500rpm like its in neutral and then downshift to 8th gear an not up shift. Message will pop up on dash stating drive modes not available while driving.

- Adairsville, GA, USA

The transmission has shifted hard since the day I brought it home. It mostly does this in the lower gear range and it seems to happen more when it when I first start the vehicle. I am not reviving the engine any higher than 3000 RPM.

Transmission issue: Intermittent loud bang upon starting the engine. Intermittent rattle during normal acceleration and deceleration. There is also harsh up and downshifts in the vehicle. During normal driving conditions, the vehicle will be up shifting and then it will lose power until it finds the correct gear, when it will then slam into gear. Again these are all intermittent and hard to make happen on demand. On occasion the vehicle will be sitting at a stop light and the transmission will bang into another gear, all while being completely stationary. The vehicle has a 13,200 miles on it, and is currently undergoing an oil consumption survey through the dealership due to the motor burning oil. All of these are ongoing issues that happen on random days and times, while both cold and warm.

The 10 speed transmission shifts erratically slips between gears when pulling in to traffic down shifts very hard whipping myself and passengers also slams into reverse and shutters I have had it to dealer 4 times for this issue they claim it's normal very dangerous truck only has 8500 miles on it and had been happening since it was new

- Vandergrift, PA, USA

Intermittently when accelerating, the transmission hard shifts coming out of 3 and 6th gear, causing the vehicle to suddenly slow down before up shifting. The stumble can be hard enough to cause the seat belt retractor to lock. Repeated visits to the dealer did not resolve the problem. They said that is normal operation.

- Stevens, PA, USA

The contact owns a 2018 Ford F-150. While starting the vehicle, the contact heard an abnormal noise coming from the transmission. The contact mentioned the noise stopped after the vehicle was started. In addition, the drive line was turning while in park. The vehicle was taken to kendall Ford of eugene (344 goodpasture island rd, eugene, or 97401, (855) 981-5490) where they informed the contact that the failure was normal. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 9,000. Consumer stated my F150 backing up at start up while in park.

Transmission makes whining/grinding noise when downshifting from 4th to 1st gear at low speeds. Transmissions makes clunking noises and jerks when shifting through higher gears on all types of roads.

- Warminster, PA, USA

10R80 transmission. Clunking, failure to shift to 9th or th gear on level open road till you have traveled for a long distance. Some time you get a message saying drive mode not available. Mode select is set to normal 1st position. Clunlks when down shifting in tow haul mode, that is if it works at all.

- Strawn, TX, USA

Transmission has a shudder when under a load. You can push the accelerator just enough at higher speeds that it doesn't down shift to make it shudder. Feels like a misfire but no codes. Also periodically when you put the truck in reverse is shakes. My dealer has replaced the torque converter and valve body on the transmission per Ford recommendation but still no fix. Truck is still well inside factory warranty.
