2018 Ford F-150 transmission problems

Filed Nov 9, 2026 · Transmission · MD

At approximately 89,000 miles, my vehicle experienced a suspected CDF drum bushing failure in the Ford 10R80 10-speed automatic transmission. Symptoms included delayed, harsh, and erratic shifting, intermittent loss of gear engagement, and unexpected gear changes that created serious safety hazards. While traveling approximately 60 mph in ninth gear, the transmission unexpectedly lost engagement, indicated first gear, then abruptly returned to ninth gear with a violent jolt. This triggered TCM diagnostic code P07F6 (Gear 9 Incorrect Ratio). The transmission also repeatedly failed to engage third or fourth gear, instead fluctuating between first and fourth with little to no power. This created dangerous situations when merging into traffic and making left turns across oncoming traffic because the vehicle could not reliably accelerate when needed. An authorized transmission repair facility identified the CDF drum bushing as the likely failure point, consistent with Ford TSB 23-2250, which addresses known 10R80 transmission shifting concerns. The transmission was ultimately replaced with a remanufactured unit incorporating Ford's updated components intended to address the problem. Ford has documented awareness of these transmission issues, yet no major recall or meaningful customer assistance has addressed affected owners outside warranty coverage. I previously purchased an extended warranty and reported harsh shifting to dealership service advisors but was never informed of the applicable TSB. I was discouraged from scheduling repairs after being told there was a three-week wait and that rental coverage was uncertain if the repair was denied under warranty. The vehicle was primarily a daily commuter with minimal towing or hauling. Failure at 89,000 miles under normal driving conditions raises serious concerns about transmission reliability and safety. Unexpected loss of engagement, incorrect gear selection, and loss of acceleration at highway speeds create subst

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.

The transmission has been replaced once covered under Fords extended warranty at 90,700 miles by the previous owner in 2022. Today the transmission has 82,000 miles on it and requires to be replace again. This 10r80 Transmission has a known issue of in early models from 2017-2020. I was stopped at a stopped at a 3-way stop, and began to pull out into the intersection to make a right. Half way through the turn the truck would not go into 2nd gear and felt like as if it was in neutral and I lost power for about 6-8 seconds. During this period, another truck coming from the left, stopped at a stop sign as well, honked impatiently and then decided to go, driving in front of me. Just then my truck slipped into gear and lurched forward almost colliding with the other truck. On top of that there was a bystander waiting to cross the street, on the other side of the crossing truck, who would have sustained serious injuries if I could have not been able to stop by truck in time. Later when it would not slip into gear a wrench light came on and the transmission was stuck in 6th gear even at a stop. This light only went away once the tuck was turned off then on and the truck shifted from 1st to 3rd gear under a heavier acceleration. I took it to the dealership the next day, and they confirmed the issue and quoted ~$9,900 to rebuild the transmission. Again, this had been done previously. The service advisor mentioned they have a lot of these transmission issues with the 10r80. I noticed a gear slip over the last few weeks and found out about this "known" but neglected issue by Ford, and they have only offered resetting the Adaptive Shift Strategy in the past.

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.

Truck has inconsistent, erratic shifting. Transmission seems to get confused or lost for a second or two when accelerating from a stop which has been dangerous a few times due to almost being rear ended. Also has shifted from 10-1-9th gear at 60-70mph at least 10 times now leaving the 10th gear unavailable and a wrench on the dashboard. Sometimes it is violent enough slamming back into gear that if roads were icy, loss of control could result. We’re having a baby in December and I wont feel safe with the child in the truck. According to many online forums, YouTube videos and talking to mechanics this is a known issue and more or less a manufacturer defect in the cdf drum that Ford should recall but wont unless its considered a safety issue, which it should be.

This vehicle is equipped with the 10 speed transmission that is know to have issues that Ford refuses to resolve. The shifting in my vehicle has become delayed and rough to the point that it is dangerous to drive. Ford says the only recourse is to have the transmission replaced or rebuilt which will cost several thousand dollars.

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.
