2019 Ford F-150: harsh or hard shifting

Filed Sep 25, 2026 · Transmission · KS

While driving on a residential road, my 2019 Ford F-150 (10R80 10-speed automatic with 88k miles) lost power to the wheels – the engine revved but the truck would not move. It did not recover after I shifted to reverse, then park, then shut the engine off and restarted. The vehicle had to be towed. This followed an earlier event on or around July 7, 2026 (at ~86,500 miles) where the transmission failed to downshift from 4th gear at a stop and stalled the engine, recovering only after cycling the shifter. The truck has a history of hard shifting into and past 4th gear for over a year now. No warning lights appeared during these events. The safety risk is that the transmission intermittently loses drive engagement and can stall the vehicle in traffic. When the engine stalls, power brake assist is lost after one or two pedal applications. Had the loss of drive occurred in an intersection or on the highway rather than a low-speed residential road, it could have caused a collision. An authorized Ford dealer has twice been unable to duplicate the fault on test drives, consistent with the intermittent 10R80 CDF clutch cylinder hydraulic leak described in Ford TSB 25-2126. The dealer’s technician suspects an F-clutch concern.

The contact owns a 2019 Ford F-150. The contact stated that the vehicle was difficult to shift into gear. The transmission was a hard shifting and vibrating. While driving 35-45 MPH, the transmission unexpectedly downshifted. The check engine warning light was illuminated. The vehicle was taken to the local dealer, where the transmission was flushed and fluids were replaced. After 3 days, the failure reoccurred. The Ford customer service was contacted. The dealer informed the contact that there were no recalls associated with the VIN. The failure mileage was approximately 151,000.

The truck has 55,000 miles on it. The truck shifted very harshly when slowing down creating a traction hazard. The harsh shifting cannot be mitigated by adjusting how it is driven. After a few days a wrench symbol appeared on the dash screen while driving on the interstate, I immediately drove the truck to the Ford dealership after the wrench symbol appeared. Code P07F7 was recovered. I was told that the torque converter is bad and the CDF hub is failing. I was told that the transmission will have to be replaced or rebuilt. The Ford dealerships own transmission specialist showed me how the faulty design is the cause for the break and showed me the new design Ford uses for the replacement parts.

My 2019 Ford F-150 3.5L EcoBoost with the 10-speed 10R80 transmission has developed severe shifting and acceleration problems that create a safety risk. The transmission frequently appears to skip 2nd gear and bangs very hard into 3rd. This 1st-to-3rd harsh shift is persistent and does not go away after the truck warms up. I also experience delayed shifts including 3rd-4th, 6th-7th, 8th-9th and sometimes 9th-10th. Downshifts into 4th can also cause a hard bang. More concerning, the truck intermittently hesitates and loses forward momentum when accelerating. This happens with light, moderate or heavy throttle. It commonly occurs during the first 3-4 miles but can happen with a cold or warm start. It can also return after the truck has been driven, parked briefly, and restarted. This creates a serious crash risk when I pull onto a main road or merge onto a highway. After I commit to entering traffic, the truck can hesitate and lose momentum instead of accelerating. I must wait for an unusually large gap in traffic because I cannot predict whether the truck will accelerate normally. I regularly have my two young children in the vehicle and no longer feel safe driving it. There are no warning lights. An independent mechanic found the transmission fluid low and topped it off. The PCM/TCM programming was also updated. Neither corrected the problem. The vehicle has not yet been inspected by Ford for this condition and is available for inspection. I am requesting that the federal safety agency investigate this as a potential safety defect because the unpredictable loss of acceleration while entering or merging with moving traffic creates a risk of collision. The hesitation can occur without warning after I have already entered moving traffic, leaving little opportunity to avoid an approaching vehicle. I believe the unpredictable loss of acceleration creates an immediate risk of a side-impact or rear-end collision.

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.

Despite several transmission services there remains a clunky shift between gears 7 and 8. The problem continues. Other owners of this model have told me that this problem eventually broke their vehicle, and they were left stranded beside the road. Stranded beside the road is a safety risk.

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.

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.

I am filing a safety complaint regarding the transmission in my 2019 Ford F-150 equipped with the 5.0L V8 and 10-speed automatic transmission. My vehicle currently has approximately 88,000 miles. The transmission began experiencing abnormal shifting, including skipping/hesitating between gears, harsh shifting, shuddering, and delayed engagement. At times it would appear to skip 2nd gear and go directly into 3rd. I brought the vehicle to a Ford dealership for diagnosis. Ford of Spartanburg performed testing and a road test. Their written diagnosis states that the PCM was tested and had no related DTCs. The technician documented delayed 1-2-3, 2-4 and 3-4 shifts, a 400-500 RPM flare during the 2-4 and 3-4 shifts, and a shudder during the 1-2 shift. The technician checked the transmission fluid and documented that the level was good but that the fluid appeared “super burnt.” The technician further stated “suspect CDF drum bushing shifted” and recommended replacement of the entire transmission assembly. The Ford dealership's estimate for the recommended transmission replacement is $8,737.05. I am concerned that a major internal transmission failure involving the CDF drum/bushing can occur at approximately 88,000 miles and result in delayed, erratic, harsh or unexpected shifting. I am particularly concerned about the potential safety implications if the vehicle unexpectedly loses acceleration or does not respond normally while entering traffic, passing, or traveling at highway speeds. I am requesting that the federal safety agency document this complaint and investigate whether this represents a broader safety-related defect affecting Ford vehicles equipped with this transmission. I have retained the Ford dealership's diagnostic documentation and can provide it if needed.

vehicle shifted from 1st to 3rd gear and as I accelerated the engine RPMs drastically increased. The transmission jumped from 3rd to 8th gear and then immediately dropped to 1st gear while I was at 40-45 mph. Due to the speed the back tires locked and the vehicle jumped from 1st to 3rd gear and I stopped. Thankfully I did not have a vehicle behind me, or they would have him me. Dealership determine and confirmed hard/harsh shifting between 3rd, 5th, 6th while skipping 4th and 5th. No codes or warnings found upon download by the technician. Technician could not replicate it shifting from high gears to 1st and locking the tires. Recommended and completed adaptive learn procedure, but vehicle is still hard shifting 3rd and 4th gear. Very concerned the vehicle could downshift from higher gears and lock the tires again which will cause an accident.

I started noticing hard and delayed shifts from 7th into 8th gear. My RPM's were not increasing when this happened, and then on a very crowded major road I lost all power, vehicle shut off and drifted, then started up and jerked again very hard. This failure could have caused a severe accident and jeopardized the well being of my wife, daughter, her friend and myself along with any other people that could of potentially been involved in a collision if one had occurred. My dash showed no warning lights. After lots of research and consultation with a private owned mechanic shop, I learned the 2019 F150 has a sever and known transmission issue with the learning tables and the transmission control module resulting in failure. Further research reveled a law suit against ford ([XXX] v. Ford Motor Company (Case No. [XXX] in the U.S. District Court for the Northern District of Illinois, targets Ford over alleged defects in the 10R80 10-speed automatic transmissions equipped in 2017–2020 Ford F-150 trucks) regarding this exact issue I was having with my truck, with only 72,000 miles on it! Bob Bell Ford in Glen Burnie Maryland, was less than helpful and the staff was rude when I was explaining what was happening and the information I learned, and quoted me a price of around $12,000.00 to replace the transmission, and that they knew there was a problem with that transmission. I had the vehicle repaired by Glen Burnie Transmission in Glen Burnie Maryland for $8,200.00. That shop told me that they replace several of these transmissions a month (confirming it is a sever issue) and the service tech could tell me what the 8th digit in my vin was based on the symptoms, and he was spot on! I was told the CDF drum and bushings failing—that cause harsh, erratic shifting, sudden lunging, jerking, hesitation, and gear slipping This repair costed me $8200.00 to replace, and another $450 to Bob Bell Ford for them to repeat to me what I already told them.

My truck has routinely been very hard shifting in 3rd to 4th gear. Recently it downshifted from 8th to 4th without warning and made a loud clunking noise. It still runs, but the transmission seems to be getting worse.
