2019 Ford F-150

I had my Transmission serviced at my local Ford dealership. After the service I was told the vehicle may shift "weird" for a while as the computer learns my driving. During this time unbeknown to me the service caused my CDF drum to fail. In the time after the service the vehicle shifted hard, which I though it was "learning" as they stated it would. As I was driving I came to a redlight. When the light turned green I started to make my right hand turn. The vehicle moved into the intersection and then shifted to neutral. During this time the lights indicating the gear started jumping around and finally the transmission went into third gear and started to move. By this time cars were waiting for me to get out of the intersection. I then decided I should not drive the vehicle anymore and get it back to the dealer. Before I reach my residence I have to cross a two lane highway. This crossing is at the bottom of steep decent through woods with lots of turns. There is a turn approximately 600 feet above the crossing. From the time you see a vehicle until it reaches the intersection is about 7 seconds. As I started out into this intersection the transmission went into neutral again and the vehicle came to a stop. Again the shift lights bounced between gears and finally settled in third gear and the vehicle started to move. I am not sure how long I was in the intersection but luckily there was no vehicles in sight. Had one been coming down the hill I probably would have been hit. I then took the vehicle back to the dealer and found out what was actually happening with the transmission. I also found out that these transmissions have a high failure rate for this same issue. Luckily I live in a rural area where there is not a lot of traffic. I feel this issue could be a safety concern and though I should bring it to the NTSBs attention.

I reported transmission issue to my dealer years ago. It started when I would start the truck in the morning and put it in reverse. It would do nothing than al of a sudden lunge in reverse. Than it would clear up and not do it for several months. I pretty much got the blow off from the dealer. Cold Oil, linkage sticking bs. Of course, now it’s out of warranty. The transmission shifts hard and even slips out of gear. It stalled tonight at a stop light because it banged into gear. I have less than a hundred thousand miles on this truck. It’s not even safe to drive down the road. You never know when it’s going to shift out of gear . Or lunge forward when it shifts into the next gear.

We were about 75 miles from the destination when going down hill the transmission would not shift to the lower gear until we were going to fast and then it would down sift very hard. While going up a hill it would down shift ok but as we got up to speed the transmission would not shift up but stay in the lower gear. Finally at very high RPM it would shift up to the higher gear with a very loud clunk. As soon as we got to our destination we took it to a ford dealer and they said we were lucky because the transmission was on verge of failing completely. Ford has a 60k power train warranty and they said even though it was less than 60K miles my warranty ran out of time 6 weeks ago. If the transmission had failed completely, the car could have had a major safety issue with the trailer behind us. We were not pulling weight more than rated but going up the mountains and the down with only brakes would have been very dangerous. I read that many ford owners are having problems with their 10R80 ten speed transmission in the larger heavy vehicles such as Expedition or F150. Ford Authority reported expeditions pulling trailers have the 10R80 transmission failing after 30K miles.

The contact owns a 2019 Ford F-150. While the contact’s husband was reversing at 5 MPH, the transmission slammed hard into reverse. The vehicle was shifting hard into reverse, and the vehicle struck a pole, causing a dent on the rear panel of the vehicle. The dealer was contacted and stated that the vehicle was operated as intended. The failure mileage was approximately 36,000.

10 speed cvt transmission. Truck was struggling with 1-3 shift, reving, hesitating, and then jumping. Hard shifts, and clunking. Took it to transmission shop got valve body replacement... less than a week later transmission could not hold 10th at highway speed kept down shifting to 9 and then going back to 10 again and again. After 15 min the display showed it in NO GEAR then 1st GEAR at highway speed and then through a wrench warning light and went into limp mode. Back to transmission shop... cdf drum failure, bad bushings and an over haul to get it back up and running again. 8,000.00. First repair 7-24 second repair 8-22.

My truck has just under 130k miles. Bought it at 18k miles. At 47k miles I had to have the cam phasers replaced and timing chain fixed. At 76k miles the trans (10r80) blew and had it replaced. At 105k miles I had to have the cam phasers replaced again. Multiple times I was denied through ford warranty. And now ford is turning there back after I had it inspected at Koch 33 ford for a reimburment in just the trans! Please help! When the transmission blew I was doing 65mph and it just dropped to first gear and i had a rear wheel lock up and skid all over. After i stopped i had no foward or backwards.

The transmission started to clunk into gear very heavily when I started my drive and then as I was driving down the highway going 60mph, the 10r80 transmission suddenly downshifted from 7th gear to 1st gear, and jolted the truck and I lost all power and it took around 5-7 seconds before the throttle was registering again to pick up speed. A car was a ways behind me but if it had been closer, there is no doubt I would have likely been hit. After this happened, in trying to increase speed back to the speed limit, the transmission would not shift back into 7th gear, and a wrench and code popped up on the dash.

Beginning approximately one year ago, my Ford F-150 has intermittently experienced a serious transmission problem during acceleration. The transmission appears to momentarily lose the connection between the engine and drivetrain. When this occurs, the truck hesitates or fails to deliver power when I press the accelerator, then suddenly and very harshly engages the next gear. The problem can occur when the vehicle is cold or fully warmed up. This creates a significant safety concern because the vehicle can unexpectedly fail to accelerate when needed, particularly when merging onto a highway, climbing a hill, or accelerating from a traffic light with other vehicles behind me. The sudden, harsh engagement that follows the hesitation is also unexpected and could affect the vehicle's stability or the driver's ability to control the vehicle. I contacted my Ford dealer on August 17, 2026, regarding the problem. The dealer indicated that they are familiar with this type of problem on this transmission and stated that their repair procedure is to replace the entire transmission rather than attempt to repair it. I was told the estimated cost would be approximately $10,000–$12,000. The truck currently has approximately 71,000 miles. Although it is no longer under warranty, I am concerned that a major transmission component is experiencing a potentially serious safety-related failure at this mileage. I believe Ford should investigate this issue and determine whether there is a defect or widespread failure affecting these transmissions. Given the nature of the problem and the potential safety consequences, I also believe Ford should provide financial assistance toward the repair, particularly if this is a known or recurring transmission problem.

CDF drum failure and torque converter failure. Started at 70,000 miles by shifting hard going into 8th gear. Now it has completely failed at 81,000 miles. It is a safety concern because now the vehicle goes straight to 4th gear when you shift out the park. Fourth gear is too steep to leave from a stop and can lead to somebody getting rear-ended. This is a well-documented problem for the 10r80 transmission and something needs to be done about it.
