2023 Ford F-150: transmission slipping

Filed Oct 9, 2026 · Steering, Suspension · PA

The vehicle is experiencing an immediate, uncorrected mechanical steering safety defect where the internal steering geometry physically slips out of specification while driving at highway speeds. During a comprehensive diagnostic tear-down by an authorized manufacturer technician at Porter Ford on September 24–30, 2026 (RO #56117630), a structural component hardware failure was verified and documented in writing. The master technician explicitly noted that the 'steer head alignment was slipping out of spec' and that the root cause was a defective 'worm gear stake causing steer head slip.' Despite three consecutive dealership service alignment attempts, the internal steering mechanism continues to slip while the vehicle is in motion. This causes the vehicle to tracking-drift unpredictably on the highway and alters the steering wheel center position, creating an immediate loss-of-control crash hazard. The manufacturer has been unable to correct this structural failure

I am reporting a safety-related transmission problem I experienced with my 2023 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly shifts violently, lurches from P to D, delayed shifting. This occurred while while driving under normal conditions creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration or propulsion. I believe this incident may be related to the known 10R80 CDF clutch-cylinder/sleeve problem. Ford technical information identifies axial movement of the CDF sleeve that can cause hydraulic-circuit leaks and harsh or delayed engagement and shifting. This condition can result in slipping, RPM flares, delayed engagement, unexpected gear changes, harsh downshifts, lurching, or loss of propulsion. This is a safety concern, not merely a transmission quality or reliability issue. Unexpected loss of propulsion or unpredictable shifting while merging, accelerating into traffic, crossing an intersection, turning, or traveling at highway speed can create a collision hazard. Because I personally experienced this unexpected transmission event, I request that the federal safety agency investigate the 10R80 CDF clutch-cylinder/sleeve condition in Ford F-150s. Please review Ford warranty claims, dealer repair records, transmission replacements, consumer complaints, and field-failure data to determine whether this is a safety defect requiring a recall. I believe owners should not have to wait for a potentially dangerous transmission failure before this known condition is addressed.

I am reporting a safety-related transmission problem I experienced with my 2023 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly lost power and was totally unresponsive. It slammed into gear and went back to normal operation. The transmission has been reset by the dealership several times and I'm told it's normal operation for it to slam into gear on the upshift and downshift. There are no lights or warnings. This occurred while I was crossing rail road tracks creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration or propulsion.

I am reporting a safety-related transmission problem I experienced with my 2023 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly shifts down violently from 10th to 8th gear, and rapidly jumping from 10th to 8th to 10th, causing harsh shifts. This occurred while driving on a highway or above 60mph. Just cruising and traveling. creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration or propulsion.

The torque converter inside my transmission on my 2023 f-150 “started coming apart” and has spread metal throughout my entire transmission and transmission cooler. There was no warning signs or lights that were shown to me other than when I noticed the problem which prompted me to immediately set up an appointment with my local ford dealer for a diagnosis and check up. It is a safety hazard because it can cause Sudden Gear Slippage & Power Loss: The torque converter may lose its ability to transfer power to the transmission, causing sudden drops in acceleration or unintended revving where the engine speeds up but the vehicle does not. This is extremely dangerous when trying to merge onto highways.Violent Shuddering: A faulty lockup clutch causes a harsh bucking sensation—often described as driving over a heavy rumble strip—usually between 35 and 70 mph. This can cause a sudden loss of vehicle control.Severe Overheating: Slippage and failing parts generate massive amounts of excess friction and heat. This boiled transmission fluid can melt internal seals, leading to fluid leaks, permanent clutch damage, and a potential engine bay fire if the fluid hits hot engine components. It can also cause Unintended Stalling and the vehicle shut off at stop lights or when driving. The truck is only 3 years old with 70,000 miles which is just outside of the powertrain 65,000 mile warranty. It was investigated and diagnosed by Trilakes ford in Branson. It has since been brought up to ford for a goodwill warranty claim to see what they can do to help with the $13,682 repair cost estimate that was given to me.

My 2023 Ford F-150 3.5 eco boost with 35,000 approx. started having issues about 2000 miles ago with the transmission. It tends to slip gears between 3-4, 4-5 and 9-10. Sometimes it isn’t bad but other times it feels like the transmission is going to drop out from the truck. I also have an issue where the truck shifts into neutral while driving but still displays it is in drive. This doesn’t happen often but 4 times now in 2,000 miles. When this occurs I can’t put the truck back into drive and go, I have to stop, turn off the engine and wait from 5-10 minutes before I can drive away. When these issues occur there is no check engine light and the dealer said there are no snapshots recorded.
