2019 Ford F-150 vehicle speed control problems

“When driving, especially from a low gear (2-5), the transmission will downshift to 1, high revving, and then slam back into 4 or 5th, depending on where it downshifted. Sometimes the rapid acceleration causes the back of the truck to start to break lose. I notice this alot when trying to get up to speed, and can usually take my foot off pedal and it will slow the vehicle and upshift.”

“On [XXX] with an empty vehicle besides I myself the driver, going south bound on [XXX] just north of twin falls Idaho I had cruise control set to 81 MPH when I felt a slow to the vehicle then noticed an uncontrolled/unprompted shift and loss of power indicated on the dash cluster jumping from 10-9-7-10-5-3-8-9 gears then transmission temperature went from 176 degrees to 205 degrees for the remainder of the trip. I proceeded to pull over and let the transmission rest for 45 mins then proceeded with my trip after not seeing any exterior damage or leaks. And it did not shift higher than 9th gear while cruise control was engaged even at lower speeds. The transmission then began to experience harder shifting, and gained a shutter like a clutch pack not engaging properly form 1-3rd gear, and sporadic shifting under light normal driving conditions at random intervals and remains to now have a normal operating temp of 204 degrees under normal driving conditions. Took it to be diagnosed at a ford dealer and it was the CDF drum that lead to a a cascade of issues leading to the transmission needing replacement.”

“I own a 2019 Ford F-150 with only 94,000 miles on it—barely approaching 100,000—and I’m already experiencing significant transmission issues. The vehicle is equipped with the 10R80 transmission, and the way it shifts gears is extremely concerning. It’s unreasonable for such a critical component to show this level of failure so early. At this rate, it feels as though I’d need to replace the transmission every 94,000 miles, which is simply unacceptable and raises serious concerns about long-term reliability.”

“Vehicle fails to accelerate and change gears (1-3); and vehicle fails to accelerate. While driving at a cruising speed and trying to pass vehicle will not change gears (8-10). Jerks and shutters while trying to accelerate. Was told that the transmission is bad and would cost $8,000 minimum to repair.”

“Vehicle will downshift from 10th gear to 1st gear at highway speeds. Vehicle lunges forward after stoplight restarts. 3rd to 4th and 9th to 10th gear shifts are extremely delayed and transmission slips during shifts. Transmission makes very loud noises and clunks when driven. Transmission lags and delays when going into reverse.”

“I leased a new 2019 Ford f150 xlt sport package in the fall of 2019. During the first year, I experienced some "choking" of the engine when I would accelerate. Nothing big, but noticeable. I mentioned this experience to the dealer at regular checkups and they informed me that it was "normal" and that if anything was wrong, the computerized monitoring system on the truck would identify the problem. I bought the truck after a 36 month lease. The choking continued to be a regular occurance, especially for the first few miles of a new drive. Around 30k miles, I noticed the issue getting more pronounced. I again asked the dealer about it and they provided me the same answer as before and didn't offer to explore the issue. Between 30K and 50K miles, the issue became more frequent and would impact the truck whether it was warm or cold. But now I experienced a hard shift between 1-3 gears and sometime 3-5-- jerking and slowing and struggling to move to the next gear. It will also bog down at times when changing into the higher gears with no telling when this would occur. Again, I asked the dealer about it, and becuase there was no safety light, they wouldn't do a…”
