Transmission fails to shift and truck fails to accelerate. It's very dangerous crossing the intersection when it occurs.

- Houston, TX, USA

Transmission bucks and skips gears in the 800-2000rpm range. When acceleration applied in the rpm range given, it hesitates and then lurches forward. It also 'jumps' in a forward motion when starting in park on a level surface. I had the transmission software flashed by Ford last year which helped for 2-3 months only. It is getting worse. Ford now wants to charge to refresh the software again since the truck is out of warranty by 6 months.

Two instances of severe loss of transmission function occurred at highway speeds within the last 5 months. The first instance occurred on flat terrain (in Michigan) with no load in the bed of the truck. The second instance occurred in hilly terrain (Tennessee) with about 500 lbs. in the bed of the truck. In both instances the transmission started cycling/jumping between first and tenth gears and several gears in between. This cycling was very fast and repetitive. The driver was forced to quickly decelerate (remove foot from accelerator peddle, apply brakes) to maintain control and pull off the highway. It was noted in both instances that the transmission temperature had shot up to around 220 degrees F. The normal temperature for the transmission in this truck at highway speeds has been observed to be around 190 degrees F. In the second incident, the wiper functionality was lost; the wipers would only work at the highest speed. (The functionality of the wipers in the first incident was not determined.) In both instances the engine was shut off to allow the transmission temperature to cool down to within the range of 190 degress F. Once the the transmission cooled to this range, the truck could be driven because the transmission functioned properly. Also, proper wiper function was restored.

I tried to have my transmission fluid changed 2019 F150 5.0L with a 10R80 (10-speed automatic) transmissions. The shop was Goss garage in Crofton MD and they would not take liability to service it because the vehicle has a Technical Service Bulletin outstanding from Ford, TSB 21-2315 and I tried to call Ford Koons in Annapolis and have not got a return call. I chatted with Shakura for 20 minutes and she brought up two other TSB and told me to talk to a dealer. I have a copy of the TSB and it looks rather involved so I-??m worried why al this run around.

Constant transmission issues where the shifting between certain gears was not operating correctly. The dealership performed a number of what they called -??Adaptive Relearns-?? to try and reset the computer but it only helped for a short period before the shifting went back into the same format where it would shift improperly. I-??ve been having the same issue since before the Warranty was up. I finally made then drive my truck to check the issue and they agreed it was in fact most likely a mechanical issue. I received a quotation for $6k to remove and disassemble the transmission to address a possible sleeve in the CDF drum that may have moved. Now my truck is out of Warranty so it-??s out of pocket to fix it. Had this been addressed properly when I brought it in originally, it would have been fixed under Warranty.

truck when approaching intersection trucks transmission goes into neutral. Causing a safety hazard This problem has been in shop 3 times with no fix also called fords main number suppled by dealer with no help from them

- Allisonpark, PA, USA

while driving the transmission had a harsh engagement when shifting gears and when leaving from a stop later the same day the vehicle would no move when applying the acceleration pedal, then the transmission engaged after a few seconds. The transmission or Transmission Control Module (TCM) needs to be addressed.

10 Speed transmission has rough shifting. Clunks, delays, gets stuck in gears and hesitates. Have had the transmission reprogrammed, valve body replaced, and other repairs from ford dealer. Most recently had a new transmission installed and all the same problems after 2000 miles if not worse than the old transmission.

- Yorkville, IL, USA

Transmission has Almost failed and is exhibiting jerking, thud sounds, and causing small whip lash affects. Transmission was serviced a year ago and "reprogrammed" the timing. The last month the transmission started experiencing hard shifting, jerking and missing gears. I took it into the dealer again to diagnose and was told I will need a new transmission at 140k miles.

After owning the vehicle for about a year to a year and half transmission developed jerking in 3rd gear occasionally. Took the vehicle to the dealership while under warranty and was advised multiple times that this was normal. Now occasionally there is a sudden reduction in power to the wheels and it almost seems like the vehicle is not shifting at all. This has happened more than once and unfortunately to sporadic to provide an actual date

Automatic transmission malfunctioned. Loss of power between 3 (third) and 4 (forth) gears. When upshifting from 3 to 4 it will experience a loss of power, however it is not consistent and seems to happen randomly. Likewise while downshifting from 4 (forth) to 3 (third) the transmission will clunk and lock-up for a 1/2 sec while the engine rpm tries to match the downshift. This has caused a loss of traction from the rear wheels while decelerating when shifting from 4 to 3. Again it is not consistent and seems to happen randomly. Vehicle has been in for complaint of these issues and dealer noted it is normal and transmission adaptive shift table needed to be reset. However this did not fix the issue. Issue is still present. There are no warning lamps or fault codes. These issues began at about 6,000 miles. I am not at over 25,000 with no resolution. Vehicle details 2019 Ford F150 3.5L EcoBoost 4x4 Lariat with the 10R80 (10 speed) transmission. Other symptoms include transmission shifting harshly and erratically between all gears, causing the vehicle to jerk, lunge, again clunk and hesitate between gears especially 3 and 4.

PowerTrain Malfunction Failed, notification on my vehicle appeared on 4/28/23, although I had been notifying dealer for 3 months prior the safety issue I was experiencing, and nearly got killed on a major interstate, on 4/26/23 my truck stalled as foot pedal would not work. Major safety of semi-trucks and other vehicles on main I30 Interstate were trying to avoid hitting me due to my vehicle abruptly downshifts from 10- to 1st gear. Foot pedal inoperable during that time. Yes, the dealer and Ford on 4/28/23 provided me a rental vehicle after my near collision experience until they figure out what to do, replace transmission or rebuild, unresolved. No the vehicle had no warnings, but did have symptons, which I took to dealer and they ran a diagnostic, and found nothing, they said there are TSBs out there with the downshifting issues, and stalling, jerking of transmission. But they said just wait it out initially, and I had to call Ford Corporate relations and raise the roof, after I nearly got killed by semi trucks from being stuck in a major interstate highway. December 2022 when it began, the dealer kept doing a reset, which seemed to make it worse, then when I told them how unsafe it was they ignored me, until April 26th when I left a voice mail after nearly being killed. I demanded service as I have a warranty and they ignored the symptoms for so long. Multiple people could have been killed on the interstate when my truck stalled, I had to try and coast to the side of interstate as the truck foot pedal did not work after downshifting from 8 to 1.

Truck has the 10 speed transmission. Has many intermittent issues including: Slipping transmission when going into gear from cold start, jerky/clunking shifting, loss of power.

- Saline, MI, USA

My 2019 F-150 has the 10-speed transmission which shifts erratically. Driving down the interstate the transmission goes into a "neutral mode" which greatly reduces the speed, thus nearly causing me to be rear-ended. When this happens, I've noticed the gear selection lights on the dash go from 10th gear to 1st gear during the "neutral mode". This has happened on numerous occasions. The last couple of times this has happened a "gear" light will display on the cluster. Shifting between 1-3, 4-6, and 7-9 seems to shift very hard and erratic, sometimes missing gears. The truck is presently at the dealership, but it has been acting up for a month. The dealership was booked and couldn't get it in until 5/1/2023

After purchasing my 2019 Ford F150 equipped with a V8 engine I noticed a loud knocking or tapping noise coming from the engine and a large consumption of oil happening. With no visible leaks I was putting about 1.5 to 2 quarts of oil a month in the engine to keep it filled. Loosing that much oil so fast could cause the engine to experience a catastrophic engine failure at any driving speed causing danger to me, my family, or other drivers on the road. Not to mention the environmental impacts caused by the engine burning so much oil so fast in possibly thousand of trucks across the country. I scheduled service with a Ford dealership. I have taken the truck in twice to have it looked at. Dealership has performed several service bulletins on it but it is still making a knocking and tapping noise and using excess amounts of oil. I have been told by ford dealership that they are aware of the problem and unable to determine if, or when, problem will be able to be fixed. This seems unacceptable knowing the truck is still under factory warranty. I have looked for answers online and found this engine in 2018-2021 Ford F-150 trucks is causing the same problem for a HUGE amount of other Ford truck owners as well.

I-??m experiencing loss of power hard jerking near miss collisions at cross traffic areas gears slipping

- Rockport, TX, USA

The contact owns a 2019 Ford F-150. The contact stated while accelerating from a complete stop to 35 MPH, the vehicle hesitated and jolted while shifting into gear. Additionally, the contact stated that while at a complete stop and depressing the brake pedal, the vehicle revved. There was no warning light illuminated. The contact stated that the failure had been reoccurring. The vehicle was taken to the local dealer, where it was diagnosed that the fuel was contaminated and a gasoline additive was added; however, the failure persisted. The vehicle was taken back to the same dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 80,000.

- Houston, TX, USA

I got the truck with 10,00 miles and currently have 47,000 miles. I have been having oil burning issues since the beginning, but it has gotten worse. When I was adding the oil myself before having the dealership do it I was having to add almost 4 qts per 5-6 thousand miles. I have been taking it to the dealership every 1000 miles for oil consumption test. Typically, my oil burns over 1/2 qt per 1000 miles so the dealership claims. I have also claimed about harsh shifting and clunking noises. Most recently I took it in for the harsh shifting of the transmission and 4 wheel drive while the did the oil test. They reflashed the transmission and topped off the oil. The dealership then forgot to put the oil cap back on (I didn't think I had to check their work) the next day after a short drive there was oil all over my engine, electrical systems, battery, suspension and underbody because of the missing cap. They took the truck back and then claimed only a 1/2 qt was gone. The dealership after a few days tells me it is all cleaned and ready to go. I got the truck with oil all over the place. So they keep the truck yet again, few days later I get the truck back and my truck is shifting worse in some ways now than before the flash. Today I had to take the truck in for an engine light about the catalytic converter failing. While they had the truck there it then gave a bunch of codes of powertrain body control all related to lack of power and powertrain failure. displaying a bunch of red lights including a gear wrench on the instrument cluster. These only appeared after the tech scan the first code. The dealership now has my truck yet again and have said it will be at least a few days.
