Ford has several technical service bulletins on their 10 speed transmission. I have 28,000 miles on my vehicle and need a new transmission. My service manager says that the earlier 10 speeds have issues with some components that are not strong enough, and that current transmissions have been strengthened. He recommended a new transmission rather than a rebuild, because not all of the weaker parts would be replaced with a rebuild. Ford should at least have to pay part of the cost of a new transmission, since their product appears to be defective. Don't have an invoice yet. Transmission on order, but about $9,500.

What owners say
My 2018 Ford Mustang EcoBoost with the 10R80 automatic transmission began experiencing hesitation, delayed engagement, and harsh jerking during low-speed acceleration (15-20 mph), especially when cold. Engine RPM would increase, but the vehicle would hesitate before engaging. The condition worsened over time and eventually the vehicle entered limp mode, causing a significant loss of power and illuminating a wrench warning light. An authorized Ford dealership diagnosed DTC P07F6 (Gear 9 Incorrect Ratio). The dealer verified fluid level, updated the PCM, and performed adaptive relearn procedures, but the problem remained. The transmission fluid was found to be dark with a burnt odor, and the dealer diagnosed an internal transmission failure requiring complete transmission replacement at an estimated cost of $9,250. This created a safety concern because the vehicle did not consistently accelerate as expected when entering traffic, crossing intersections, or merging onto roadways. Delayed engagement and loss of power reduced the ability to accelerate when needed. The vehicle has approximately 82,256 miles and has been maintained according to Ford's recommended service schedule. I am also aware of numerous publicly documented owner reports, technical discussions, and litigation involving the Ford 10R80 transmission used in vehicles from this generation. One of the commonly discussed concerns involves the CDF drum design in earlier 10R80 transmissions. My understanding is that Ford later revised the CDF drum design in subsequent production; however, when I contacted Ford regarding this transmission failure and requested assistance with repair const, they advised that my vehicle was not covered by any recall, customer satisfaction program, or warranty extension related to this issue. I am submitting this report so that my experience can be considered together with other reports to determine whether a broader safety-related defect exists.
My vehicle would suddenly downshifted to first, constantly seek for gears, loss of traction from not finding gears, and transmission died at 120k miles.
The contact owns a 2018 Ford Mustang. The contact stated that while driving at an undisclosed speed, the vehicle suddenly came to a stop while attempting to shift to second gear. The contact pulled over to the side of the road. The contact stated that the failure had been recurring while driving in second gear, which required the contact to release the accelerator pedal before the vehicle could shift to second gear. The vehicle was taken to O'Reilly’s, where it was diagnosed with transmission failure. The dealer and the manufacturer were not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 70,000.
I have a 2018 Mustang GT with the 10R80 transmission. The transmission started giving me problems like slamming and slipping while shifting and sometimes jumping in and out of gear when drinking in the highway.The problem came from an engineering is with the CDF Drum... Ford has updated the CDF Drum and has fixed the problem. Ford never issues a recall to fix this problem with the vehicles produced with this issue but instead just used the updated production parts in the later models leaving the customers like myself to have to either pay out of pocket or rely on a warranty or after market warranty company to have this very expensive issue fixed. Right now as I am writing this, my car is in the transmission shop. Please help me. When I did a Google search of the CDF Drum issue, this is what was quoted: "The 2018 Ford Mustang GT with the 10R80 transmission can experience issues with the CDF (Clutch-Drum-Forward) drum, specifically with its bushing. This problem can lead to slippage, harsh shifting, and potential transmission failure. Ford has addressed this issue with design revisions to the CDF drum, including adding a lip to the bushing to prevent it from moving and causing fluid leaks."
Yes, if the federal safety agency communicates with me that they need to look at my transmission, and I am either provided another equal mode of transportation or paid for my lack of ability to use my vehicle during inspection/possession/out of service by the federal safety agency. 10R80 10 speed transmission was finally replaced under warranty by FORD in January. The new transmission has been problematic and getting worse since march. Transmission flairs/slips. Transmission acts as if the brakes are put on at times/acceleration is greatly decreased for no reason. Hard shifts at times… I and other others are put at risk due my car, responds erratically and this could become a safety issue by causing a crash or loss of control by the Ford MACH 1 Mustang. Transmission often is too high gear and the as a result, the engine is lugging too much. No idiot, lights or warning lights have come on this go round. The police have not inspected the transmission. I would not expect them or ask them to inspect the transmission because I would assume 99% of them would know very little to nothing about it. Same goes with the insurance company. Ford and Chevy the two manufacturers of this transmission are both aware of the multiple problems of this poorly designed and manufactured transmission. I was not sure what incident date you wanted. The first transmission or second transmission? There are multiple incidents and issues starting from my first ownership of the car when I first test drove the car and had 550 miles on it. The original and replacement transmission are both and have been problematic and unsafe.
The back up camera periodically has a black screen or a blue screen. The sound of an object getting closer some times works and sometimes doesn't. Also the lines showing where the tires are on the camera do not appear either. Transmission was replaced under warranty for several issues. It's the 10 speed version. However even with the new transmission. It tends to lag on gear 4 mainly.
Transmission Issue. Transmission slams into 2nd gear when downshifting from 3rd. Transmission has grinding noise when going from 4th to 5th. Potential safety issue due to potential transmission failure. Yes, problem is reproducible, however, it is awaiting inspection at Mike Patton Ford. No warning lamps. Car has had transmission issues intermittently since 4/2020. This issue started 2 weeks ago.
For three years, this Mustang will lurch frequently after you shift into first or reverse from park. I had it looked at Paradise Ford 3 years ago and they REFUSED to look at transmission until the car had 125k miles on it. At that time, the car only had 98k miles on it. I tried to insist, but they refused. The service helper was named Mark, I believe. The other day I was driving on a 10mph park road .....more like coasting because it was a low speed limit. The car suddenly jerked forward. Today I took it into Gary Yeoman Ford in Palm Bay, FL for a transmission check. The service advisor was Jason. They said there was a cdf hub issue and stated I needed a new transmission for 6600.00. Of course I refused and came home to research their "diagnosis". I found an article about a,10R80 bushing that has caused the same exact problem is other Mustangs. I feel like they were giving me the run around. I don't want this to cause further problems. It should have been fixed at Paradise Ford. I have owned this car for 5.5 years. I'm quite familiar with how it runs. Please advise.
After driving for 2 blocks, my car would not drive when hitting the gas pedal, the engine only reved. Unable to move the car in any gear, pedestrians helped push my car out of the middle of the road. Towed the car to a Ford dealership because the Ford app on my phone said "shift solenoid stuck in off position". Upon diagnosis the dealership said yes the solenoid is stuck in the off position but now the gears are slipping and you need a brand new transmission. This is the 10r80 automatic transmission that has had problems like this nationwide. I don't understand how this has not been recalled yet. With 63,000 miles a transmission should not be failing. There have been hundreds of documented cases of this specific transmission failing for countless reasons involving internal components.
