Automatic Transmission Control Module problems of the 2017 Ford F-150

2017 f150 with only 48,330 original miles. Having issues with transmission stalling,jerking in between gears. After last night I have had enough due to an almost potentially fatal accident. While making a left hand turn the transmission stalled for way too long and an 18 wheeler came over the hill ( it’s a blind spot turn) and came very close to hitting me broad side of my truck. This issue could have costed me my life. The transmission fluid is fine as it was checked very recently at my last service less than 100 miles ago. The dealership wants 200 dollars just to hook it up to a computer just to see if the tcm is showing any codes. I have already had that checked for free somewhere else and it is not. The dealership will not do anything unless I pay for that to be done first. I cannot afford to give away 200 dollars for free. But if I give them 200 dollars then they can give me an estimate for repair that ranges from 1000 to 10,000 dollars which is what other customers have paid or been taken advantage of for that amount.

On 4 occasions, my f150 has went in reverse when transmission was in the drive position. The truck would travel backwards 3 to 5 feet before shutting off. The first time happened at a stop sign. Nearly backed into another vehicle. Pcm was reprogrammed. 2nd time occurred on leaving my driveway. Ford replaced an abs module. 3rd time happened in front of my house. Ford found bent pin on pcm. 4th time occurred at waste facility after unloading trash. Vehicle went in reverse when transmission was in drive. Vehicle went backwards at least 3 feet. Nearly backed into a Ford f250 and pinned driver of vehicle between the 2 trucks. Ford has changed a relay. I have contacted Ford by chat, phone, and email. The case manager refuses to communicate with me about this matter.

Component: 6r80 transmission lead frame safety: driving at 70mph on the interstate on 07/23/2025 and vehicle violently downshifted while in cruise control. Rear tires locked briefly. Driver and passenger were restrained by the seat belts or there would have been a loss of control. I was able to pull to the side of the road. Reproduced: this is the third time in a year that this has happened. Independent shop is scheduled to inspect. Dtc codes p061a and p0722 are logged in the pcm. Warning lamp: after the incident, an amber wrench icon was displayed. Still displayed after restart. Disappeared after 2nd start.

The contact owns a 2017 Ford F-150. The contact stated while driving 30-35 mph, the vehicle jerked while in first gear and briefly lost motive power before slamming into gear. The gear shifter notification disappeared. The contact pulled over to the side of the road and turned off the vehicle. The vehicle was restarted; however, the vehicle was driving rough before downshifting to first gear. The vehicle was taken to a dealer who diagnosed that the transmission lead frame was damaged, which short-circuited the pcm (power train module) and caused the transmission to fail. The contact was advised that the pcm and transmission needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure and transferred the contact to the NHTSA hotline. The failure mileage was approximately 66,000.

The contact owns a 2017 Ford F-150. The contact stated that on numerous occasions while the vehicle was idling or after the vehicle was started there was a loud rattling sound coming from the hood. No warning lights were illuminated. The vehicle was taken to the dealer where it was diagnosed that the variable camshaft time unit pcm reprogram for cam phaser rattle needed to be performed. The vehicle was not repaired. The contact referenced the customer satisfaction program: 21b10 (variable camshaft time unit pcm reprogram for cam phaser rattle) however, the manufacturer was notified of the failure, and the contact was advised to call the NHTSA hotline. The failure mileage was approximately 39,150.

The contact owns a 2017 Ford F-150. The contact stated while driving at an undisclosed speed, the transmission started shifting abnormally. The contact stated that the vehicle was sputtering, vibrating, and shifting unexpectedly before returning to normal operation. There were no warning lights illuminated. The contact stated that the pcm had previously been reprogrammed under TSB: 17e01 (power train) prior to the failure. The vehicle was taken back to the dealer and the pcm was re-flashed; however, the failure reoccurred. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 63,000.

Vehicle is presently out of service for it's 3rd repair attempt of the same transmission related non-conformity and has been so for greater than a cumulative 30 days as of 10/4/17. The same safety issues occurred under identical driving conditions multiple times while traveling on the highway. While in motion on the highway at approximately 65 mph the vehicle's 10 speed automatic transmission locked up in 7th gear. At the exact time this defect occurred the �check engine� alarms and dashboard lights sounded. Thereafter, the vehicle was unable to downshift or upshift from 7th gear no matter what speed. Then vehicle engine stalled completely once maneuvered to an exit ramp and slowed to a point where 7th gear could no longer sustain forward operation. There is a documented 1st repair attempt appearing to be the identical issue but was made prior to my taking possession of the new vehicle. The second occurred on 8/29/17 at 427 miles on vehicle. And the 3rd on 9/14/17 and has been in service through present day. To date repair attempts have included in chronological order: replacing "all 4 speed sensors to transmission and the transmission internal harness"; replacing "tcm - transmission control module"; and in progress (incomplete) replacing the tcm "harness". The first two repair attempts had zero positive effect on the safety related non-conformity, and the 3rd 'in-progress' still has yet to be completed past the 30 days out-of-service period.
