The 10-speed automatic transmission on my truck shifts hard and inexplicably when upshifting and downshifting, especially in low speed stop and go city traffic. The jolts are hard and cause an dramatic 'braking' action that has almost resulted in a few accidents. The transmission was rebuilt by Ford at approximately 9,000 miles and current has just over 16,000 miles.

Transmission shifts erratically and harshly, mostly during in town situations. The transmission doesn't respond quickly enough to changes is accelerator causing late and unexpected shifts. In one instance, I was going up a steap city hill, the truck slowed and I continued to slowly increase pedal input to get up the hill. All of a sudden the transmission had uncontrollably dropped several gears and seeing that the transmission hadn't down shifted, the accelerator was nearly to the floor. The vehicle unexpectedly took off at that point. Luckily no one was near by, but if I was in a traffic situation or had there been any pedestrians near, someone could of been killed. I've taken this vehicle into Ford dozens of times since new an thy have replaced the valve body twice. The transmission issues have not changed.

F-150 will sometimes roll when parked on an incline. The problem is intermittent, and the F-150 will not always roll. So far, the F-150 will only roll between 6' to 24'.

Vehicle has hard shifts and has been reprogrammed 3 times in the last year. PCM was reprogrammed due to a chain rattle or slapping at 1500-2000rpms, gas mileage has went to 13-14 mpg highway after last attempt to fix.

10 speed transmission shifts very hard into reverse (loud 'thunk' heard along with a jarring motion felt inside the cab). Majority of the time this happens shortly after the vehicle has started (I let the engine 'idle down' before shifting into gear). Ford of Canada reprogrammed the transmission a number of times, and that seems to solve the reversing issue temporarily. Now live in the usa, and in addition to the reverse issues the vehicle will 'jerk' or 'stall' when shifting between 3-4-5-6 gears shortly after started. Unfortunately neither of these are an 'every time' occurrence, and have happened in both cold and hot ambient temperatures. To Ford Canada's credit they did attempt to solve the issue multiple times...we'll see how Ford usa deals with the situation.

While driving 75 mph I floored the accelerator pedal to pass a vehicle in an 80 mph zone. The transmission down shifted from 10th gear to 6th gear so hard I thought I had been rear-ended. I have been able to duplicate the situation 2 additional times.

On multiple occasions the transmission has come out of gear between shifts and remained out of gear for extended periods of time. The most notable scenario is when pulling a 7500 pound load while descending down a mountain. This has resulted in loss of braking power and overall control of the truck and trailer. This has created an unsafe environment for myself and my family while hauling our travel trailer. The 10 speed transmission is notorious for such behavior and Ford refuses to acknowledge this. I have made multiple attempts at bringing it in for service at multiple dealerships. There is no known fix for this problem.

My vehicle I purchased in 2019 second owner is now not running. I am unsure as to what is going on or why it stalled on me approximately 3 months ago. I filed a claim with my insurance company they closed it without assistance. I had it towed home. It will start up but it has a really loud clanging in the motor area. I don't know what's going on with it. My vehicle has not been neglected and it has been taken care of and I don't understand why it's not running to only be 2 years old. I was driving my vehicle to pick up my daughter from work in town. I noticed a very loud sound and I pulled over at a local circle K and it didn't start back up at that time. I am finding recalls, but not specific to my VIN.

Driving at speed, push on accelerator to pass other vehicles or enter highway from onramp, transmission downshifts so hard with a loud clunk that tires lose traction and it feels like my vehicle has been struck. This has been happening since the truck was new. The dealer has reprogrammed the PCM per recall 182274A, but the reprogramming has not fixed the issue. If anything, it has been worse and happens more frequently than before the reprogramming.

Numerous times I have been driving and my transmission lags so much that 8 slow down at least 5 to 7 mph although it hasnt caused an accident yet I feel an accident could easily occur especially in situations were I would need to accelerate quickly there has also been multiple class action lawsuits brought against Ford involving these type of particular incidents regarding the 10R80 transmission

Transmission gear shifts are clunking and noising and sometimes slips gears mainly around 3 and 6 gears

- Pearland, TX, USA

While driving, there has been rough intermittent shifts/acceleration, particularly from a stopped position. I have noticed it happens between 5-7 gears. Vehicle will be stopped at a stop light, as you accelerate, the vehicle will go through first few gears with normal acceleration and pick up speed, the sudden jerking of the vehicle seems like it just did an engine break(?). vehicle will be accelerating to 40+ mph and feel as if it did a sudden brake and decelerate rapidly to than resume acceleration. Additionally, when vehicle is parked, when switching between park and drive or park and reverse, the shift is sometimes rough as if the clutch was never engaged and it was forced into the drive mode. Not only will the be a large noise, but a slight jerk. Also, I have had my phasers replaced already due to loud engine noise.

Was on a driveway with incline towing a trailer 500 lbs, looping around started down in gear shifted then free wheeled 20 to 30 feet slammed into gear. Second time it had happened. First time around a corner with a trailer same thing, free wheeled then slammed into gear. I have less then 20,000 miles on the truck. Every time I go around the corner truck shift hard. This has always been on a city street while the truck is in motion. The free wheeling was an unsafe condition. Transmission is the faulty part.

- Olympia, WA, USA

The vehicle will shift harshly at times and sometimes will not shift at all. We were on freeway on ramp and the transmission just didn't shift leaving us basically almost in an accident from no acceleration as we were trying to merge. This has happened more than once. Can't replicate at dealer.

Control module for the powertrain is malfunctioning causing problems with overall driving vehicle. I was getting lunch and while driving back to the office a wrench sensor showed up on my dash. I stopped and had to look up what the icon meant and apparently it had something to do with the powertrain on my vehicle. I immediately called the dealership and had it looked at. They informed me it was a control module problem and ordered a new one for me.

When shifting into 4th gear the vehicle will shift roughly almost as a brake tap before automatically increasing on its own to 25-28mph. This even occurs with speed control on. All of this occurs while in motion on city streets and entering highways. This has been occurring for the past 8 months. Every time the vehicle is in motion.

- Pensacola, FL, USA

Transmission shifts rough and clunks. Most noticeable going from gears1-3 and from 4-5. will randomly shift and almost cause whiplash when running on the highway with cruise control on.

- Horace, ND, USA

Truck has had transmission issues for last 800 miles. Truck now has 12700. Shifts hard and slips especially 3-4-5 gears. 5th gear the worst on slipping, almost as if I put the truck in neutral, then it finds the gear and bucks. Definitely a hazard to drive. I have brought it into Ford 3 times, the first time they applied a tsb, second time they said it was normal and refused to do anything. I called Ford and sent it in for a second opinion they said they agree transmission needs work but refuse to work on it as the first dealership only one who can get paid for it.
