Unexpected gear downshift accompanied by a temporary rear wheel lock-up. This occurs at highway speeds and has shifted from 6th gear to 2nd gear multiple times at 50+ mph. This causes substantial safety concerns to both those in the vehicle as well as other vehicles on the road in the immediate proximity. When this occurs speed is restricted suddenly/immediately by a reduction of 5-12 mph. This causes severe impact to passengers. At low speed the gears shift sporadically between all 6 gear ranges impacting drivability. The vehicle has been inspected several times by Corwin Ford however they clear the codes and 'can not replicate' which correlates to the dealership deeming it safe to operate. There were multiple warning lights/lamps, messages when delivered to the dealership. Those were then cleared prior to 'diagnostics' as that was 'their process'.

The contact owns a 2016 Ford F-150. The contact stated while driving approximately 30 MPH uphill on several occasions, the vehicle made an abnormal grinding sound. There was no warning light illuminated. The vehicle was taken to the dealer; however, the failure could not be duplicated. The contact stated that the failure was intermittent. The vehicle was taken to Lonstein's Motors Inc, where the gears were taken apart, and the mechanic diagnosed that the integrated wheel end (IWE) of the 4WD system was partially engaging unintendedly, causing gears to grind against each other and to become damaged. The mechanic noticed the presence of metal shavings. The mechanic replaced the left and right hub assemblies, two actuators, the vacuum lines, and the tubing solenoid. The vehicle was repaired. The contact related the failure to TSB Number: 18-2273. The manufacturer was notified of the failure and informed the contact that the vehicle was not covered under warranty. The failure mileage was approximately 49,000.

happened a couple times within a week or so as the first time i was not sure what happened and there were no check engine lights but the second time i realized something was wrong and the check engine light was on. but while driving doing about 55-60 on my way home from work it happened and it seemed like the truck went from 6th gear to 1st throwing me forward and the dash went blank and then came back on after a split second and there was no response from the gas and then pedal was responding again. i pulled over and there were check engine lights on as well as the warnings for the cross traffic sensors. i then brought the truck into the local ford dealership and they said it was the valve body gone bad. they put in a new one and it wouldn't take programming so they put in a second one and i haven't had a problem since.

The problem is my transmission a 6R80 my safety is put at risk when getting onto the highway. And the truck slips, third, and fourth gear causes me to gradually speed up on an interstate. The truck has been inspected by Ford. They replaced a torque converter, but not even a year later. Now it's slipping, gears and shuddering real bad.

- Fayetteville, NC, USA

Power train failed and truck began to jerk and I lost control of the throttle. I had to throw myself (the truck) on the shoulder to avoid danger. Blinking lights on the dash board occurred. San Leandro Ford diagnosed issue as bad transmission and replaced it in November 2024. Inspected on site by authorized dealer. Told me customer problem must pay to have it replaced!! When I tried contacting national Ford representative and Bill Brandt dealership in Brentwood where purchased in Oct. 2016, no one wanted to take responsibility.

In May of 2023, the transmission downshifted unexpectantly while going 50 mph from 6th gear to 1st gear for a second, causing the rear tires to lock up for that moment before shifting back to 6th gear. This caused a quick loss of control and reduction of speed while in traffic. Luckily no accident occured during this. If it had not shifted back to 6th gear, the result would have been much different putting myself and others on the road at risk of an accident at high speeds with traffic behind the vehicle and oncoming traffic. Prior to this incident the truck would occassionally not start and the gear selection indicator was not illuminated as normal and the engine light would occasionally come on. Speaking with Ford dealerships they identified it as the molded lead frame connector within the transmission. I'm unsure of the damage this has caused on other parts from the significant shift change at high speeds and I'm concerned of what has been damaged but not shown as of yet. They replaced the molded lead frame connector at a cost to me and the truck has not had that issue since.

Component/System: Automatic transmission. Yes, the failed transmission components are possible but not likely available for inspection upon request contingent on the repair shop not having scrapped them. I-??ve had two transmission rebuilds due to repeated failures. Safety Risk: The vehicle unexpectedly downshifted to a lower gear at highway speeds without warning, causing sudden deceleration. Also, at red lights causing jolting or delayed acceleration. This put my safety and others at serious risk of rear-end collisions or loss of vehicle control, especially during high-speed driving, in addition to other things. Confirmed by Service: Yes, the issue was diagnosed and confirmed by two independent repair shops. Each diagnosed severe internal transmission failure consistent with sudden mechanical shock. The failure of the transmission had codes displayed indicating such, and I have a print out from the mechanic prior to the rebuild as I wanted to confirm it was not any other issue before rebuilding. Inspections: The state of New Jersey has not inspected this vehicle. Warning Signs: There were no dashboard warning lights, error messages, or audible alerts prior to the failure that reasonably could have been linked to such event(s). The first rebuild occurred in early 2023, and similar failures repeated despite full rebuilds. No advance indication was ever given before the vehicle downshifted. Second rebuild was in the Fall of 2023. In prior instances to rebuilds, there were wrench light warning alerts indicated on dashboard, however they made no sense and clicking OK dismissed them with no re-alert or info pertaining to such. When this did occur, and since nothing could be linked to it in the average drivers head, it was assumed an accidental notification.

The truck grinds when it down shifts to third gear when yoyr driving. While driving the truck skips and makes a terrible jerking motion. When it does it, it feels like the bottom of the truck is going to fall out. Sometimes you have to pull over and turn the truck off and on. The truck is available for inspection if requested. This is a huge safety issue especially when the gear sticks downshifting to 3rd and you have to pull over fast. The truck has been brought in to several shops and we get told unfortunately this is a known problem with Ford F150s. There was a check engine light that came on before it broke down this last time.

Transmission would not know what gear it was in and go into limp mode and at high speeds it would lock up the back tires. It would also not go into gear reliably after it warms up. I had this repaired 10/26/ 2024. I heard on the radio today that you were investigating this problem for a recall.

- Weatherford, TX, USA

While driving my 2016 f150 truck was driving at 65mph, the transmission down shifted into first gear smoking the back tires and reduce speed in the matter of seconds, with cars behind me braking to avoid me.
