2018 Ford F-150: complete transmission failure

Filed Nov 9, 2026 · Transmission · AR

At around 45 miles per hour the transmission shifted hard between gears and almost like a jerk and routinely does this now. Had diagnosed and find its known tech bulletin on this transmission. Ford now has me on hook for new transmission. Just adding my complaints to long list of others with 10r80 transmission issues. Hoping ford will turn into recall help customer.

My 2018 Ford F-150 is a regular-cab, long-bed pickup with a 10-speed automatic transmission and approximately 115,000 miles. The transmission frequently delays or misses both upshifts and downshifts. At times, the truck feels as if it goes into neutral for two to three seconds before the next gear engages. At low speeds, around 5 to 15 mph under light acceleration, the engine RPM rises and gear engagement is delayed. This happens under load and during ordinary driving without a trailer. The symptoms have worsened over the past several weeks. AutoNation Ford North Scottsdale inspected the truck and reproduced the problem. The transmission software has been reprogrammed twice. The repair order states that after reprogramming and clearing the adaptive settings, the technician road-tested the truck and found that it would not shift into second gear. The technician recorded findings indicating an internal transmission failure and recommended transmission replacement or teardown for inspection. A service warning light also came on during service at the dealership. The truck still does not shift properly. The delay in gear engagement makes acceleration unpredictable. If the truck briefly loses drive while I am merging or crossing traffic, I may be unable to accelerate when needed, putting me and other road users at risk. I am asking the federal safety agency to investigate the delayed and missed shifts and the temporary loss of drive.

3 separate things recently happened. First the cam phasers went out, $4600. Second, only months later, the transmission went out, $7100. Third, it is throwing a p0420 and p0421 codes and the catalytic converts need replaced, at least $2000. All of this under 100k miles.

Hello, so while driving I am noticing a loud, hard thunk between gears. It is really noticeable when pulling our camper. When pulling our camper it is so loud and so hard I that if I have coffee in my cup holder, it would spill. We have contacted Ford about this and they are denying there is a transmission issue with their 10 speed transmissions. I feel there should be a recall on these transmissions because there are thousands of F150 owners having the same issue and replacing a transmission the way prices are for everything, who can afford to pay thousands of dollars for a new transmission and have it replaced.

2018 Ford F-150 5.0L with 10R80 10-speed transmission, approximately 86,000 miles. The transmission began exhibiting abnormal shifting, including missed shifts and loss of propulsion. On multiple occasions while traveling approximately 60 mph, the vehicle suddenly lost power/propulsion. During these events, the gear indicator changed from 10th to 1st and engine RPM appeared to increase. I do not believe the transmission physically engaged 1st gear; the actual gear engaged is UNKNOWN. The unexpected loss of propulsion at highway speed created a safety concern because the vehicle would not respond normally to accelerator input while traveling with traffic. The transmission also malfunctioned when accelerating from a stop. It would sometimes have difficulty shifting through approximately 3rd, 4th, and 5th gears and lose propulsion for approximately 3–5 seconds. I would release and reapply the accelerator trying to get the transmission to engage a gear. This could be particularly dangerous when entering or crossing traffic. An independent transmission shop inspected the vehicle and documented codes P0732, P0734, and P07F7. The shop found the transmission fluid full but dark and diagnosed an internal transmission failure requiring replacement. The transmission was replaced on October 5, 2026. To my knowledge, the original transmission was not disassembled, and the exact internal failure is UNKNOWN. The vehicle was not inspected by Ford. There was no crash or injury.

I have a 10 speed automatic transmission that intermittently works in 2nd and third gears. It began doing this at 60,000 miles. I'm not sure if it is the adaptive learning transmission control module (TCM) or the transmission itself. Ford dealer wants over $10,000 to replace transmission. The car is unsafe when pulling into traffic and it won't accelerate half the time.

My Ford F-150 Supercrew XLT 10R80 10-speed completely failed resulting Ford replacing it with a new transmission unit for a cost to be of $7,300. As the transmission failed at 96,000 miles the gears would be skipped with harsh shifting, not fully engaging 4th gear and at times while driving would refused to shift into any gear and high revs and me unable to accelerate. I was nearly involved in a crash when I would pull out into traffic legally but suddenly unable to accelerate and approaching cara from the rear needed to suddenly brake and change lanes to avoid a collision. All diagnosis was conducted by Ford. At first it cost me approximately $300 for them to drain and fill transmission fluid. When that didn't fix the problem they then said it was the DCF drum failure at a cost of $5000. When they were unable to fix it they informed me that they needed to install a brand new transmission at a cost of $7,300. Current mileage is approximately 98,300 miles. As a prior certified LEO Traffic Homicide Investigator, I was terrified driving the truck knowing what could happed if it failed as I was crossing traffic or pulling out and fail, as is had already and therefore I was unable to use my vehicle.

The internal mechanical failure of the Ford 10r80 transmission due to design fault causes unsafe driving conditions as the transmission stalls (fails to power at request) or lunges (powers forward without driver input) causing unsafe conditions for vehicle occupants and nearby vehicular & pedestrian traffic. My vehicle exhibits two well known and documented conditions; stalling and lunging forward. The most common failure is that the transmission fails to shift from 1st to 3rd gear in a low speed condition (e.g. navigating parking lots amongst pedestrians). Upon the failure to shift, the vehicles computer system senses this, overrides by raising the vehicle RPMs significantly without driver input to do so, the vehicle then hard shifts and jerks forward several feet in an uncontrollable manner. Anticipating the jerk and overriding with the brakes fails to stop the vehicle from lunging forward. The second most common failure is the transmission totally failing to provide drive. A common scenario would be sitting at a traffic light waiting to make a left turn. Upon the opportunity to make a safe left turn, the vehicle at times will roll slightly forward (in its first gear), it will then attempt a shift while the vehicle may potentially still be in cross-traffic, and the vehicle at times will fail to drive, without any inputs (brake, gas, manual shift) getting the vehicle out of the no-drive condition, and leaving the vehicle subject to a dangerous potential for collision or safety hazard. The issues with the 10r80 transmission failures are well documented, well understood by Ford Motor Company, and specific to my vehicle have been identified by a reputable dealer as requiring repair. My vehicle's transmission is exhibiting failure at 47,000 miles. No warning indications exist prior, during or after this repeatable incident. Ford has since fixed the design flaw, but refuses to address the safety issue with vehicles manufactured before the re-design.
