I then pulled over when it was safe, turned the truck off and then attempted to turn back on with no success due to the shift indicator no longer lighting up. This matches up with the current recall for this particular vehicle.

As I was leaving work and I went to pull out onto hwy 45 in columbus ms and the transmission in my 2017 f150 jerked and hesitated between 1st and 2nd gear and almost got me hit on the driver side by oncoming traffic at a speed of 65+.

17 Ford f150 10 r 80 transmission has been a problem since the day I purchased the vehicle in 2022. Ford dealerships across the country have known this has been an issue and our neglecting to recall the transmission. Ford continues to deny any problems with the transmission after a revised cdf drum in 2025 and 2026, but the problem still occurs.

The vehicle experienced a sudden and violent downshift while driving, causing a severe jolt to the drivetrain. Following this incident, the transmission entered a 'limp mode' and remained stuck in 2nd gear, refusing to upshift to any higher gears. This made it impossible to maintain normal traffic speeds, creating a significant safety hazard on public roads. The vehicle is now effectively inoperable. A Ford dealer and Ford corporate (case on file) have confirmed this is related to recall 26v237, but they stated that a software remedy will not be available until July 2026. This delay for an actively failed vehicle is unreasonable and poses a continuous safety risk.

At 90,181 miles, the 10r80 transmission in my 2017 Ford F-150 suffered a catastrophic internal failure. The vehicle exhibited violent, hard shifts between gears 2 through 4 with no check engine light or warning indicator, giving zero warning the drivetrain was failing. Sheehy Ford in [xxx] reproduced the condition. Their diagnosis on ro xxx: "harsh 4-6 shift-internal fault. " teardown revealed a fractured cdf drum with metal debris that migrated into the valve body. The dealer removed the transmission and performed a full overhaul, replacing the cdf drum, clutch cylinder, forward clutches, and valve body, and flushed the cooler and converter. Total cost: $6,846. 30, entirely out of pocket. This is a serious safety defect. A fractured cdf drum can cause sudden loss of gear engagement, unexpected downshifts, or transmission lockup at highway speed, any of which can result in loss of vehicle control and severe risk of injury or death. I use this vehicle daily to transport my two young children (ages [xxx] and [xxx] ) to and from daycare. This defect endangered their lives, my life, and other motorists, all with no diagnostic warning. This failure is consistent with widespread defects in Ford's 10r80 transmission, currently the subject of class-action litigation. A transmission should not need a $7,000 overhaul before 100,000 miles. Ford is aware of this pattern and has failed to recall. I am filing to ensure NHTSA has a complete record of another 10r80 failure that directly endangered occupants, including small children. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Transmission will jump out of gear. Transmission will shift from 1st to 5th skipping all other gears. Transmission will stay in a high gear even when I’m stopped. Transmission will get confused on what gear to be in and jump all around.

These problems will occur every few weeks and has been going on for more then a year. Sometimes going a month or two without any issues.

Had powertrain engine light come on in Jan 2026 and transmission would hesitate and had problems with downshifting on interstate. Fiord said no recalls on the vehicle. . I, had transmission service done and still had problems with it downshifting while on freeway. On March 29,2026 truck would not start. Message came on stating it was in drive when it was actually parked. Had to tow it in. Diagnostic test was done with powertrain control module parking aid module body control module etc problems reported. The same problems that other Fords were having but Ford said this truck wasn’t included. Auto shop got the part directly from manufacturer and installed the parts. Battery was low because of this and had to be replaced. Total cost $1730. 64. We only have this vehicle and had to get a rental car while in shop. Also we are on a limited income on social security and therefore this put a huge financial strain on us. We and other could have been seriously hurt and truck damaged as we were on interstate 80.

I was on the freeway in eastern colorado going 75mph which is the speed limit. Luckily nobody was behind me. My truck went from 6th gear to 1st out of nowhere and I didn't know what to do, very fast deceleration and I almost lost control. I was able to manually shift with the buttons on the gear shifter back up to 6th gear. Recently on the freeway it's been acting awkward and not shifting out of 4th gear.

I've had the transmission replaced under Fordprotect warranty and subsequently another torque converter and subsequent to that, a new program installed to repair low rpm shudder. Under mild acceleration at interstate speeds (65 to 75 mph) it now hunts for gears with random upshifts and downshifts while failing to maintain or increase speed which constitutes a safety hazard.

Sudden downshift at highway speeds.

Past issue was when vehicle was in tow/haul mode it would down shift unprompted. Currently when you break hard it won’t downshift and stays in previous gear causing the inability to accelerate with out putting in park the back in drive. I have almost been hit twice on interstate while manually shifting. My truck is currently in a Ford shop and they say I need a new transmission?? however there are no problems with transmission issued by computer.
