What 1,066 owners told NHTSA about the 2017 Ford F-150 Crew Cab

After I purchased a RV and making the trip home, we went through several stop lights. As we were slowing down to make a stop at light, the vehicle made an abrupt downshift. Seemed like it was in fourth gear and went in to first or second gear. The vehicle jerked and the rpm went to around 6000. I thought my engine was going to blow up!! Scary and felt dangerous! Then it happened again approximately 10 miles down the road. I haven't experienced this since this date but I haven't pulled anything since then either. Please make this a recall. It isn't just the 2014 model. I have V8 5.0 6 speed transmission. Please help.

Loss of gear at highway speeds. Went from 10th gear to 1st. Tires locked up and an error for the drive train showed up on the dash. Pulled over, restarted vehicle and it seemed to work. This has happened 3 times since. I was luck that no vehicles were around me or I would have caused an accident and potentially chasing injury to myself, my family or another driver. Dealership was not able to locate issue. Told me to keep driving and report back when it happens again.

I have had transmission gear changes abruptly/rough on my 6 speed 2017 XLT F150. It seems to happen more often downshifting from 4th to 3rd gear. I reported this to dealer early after purchase when I still had factory waranty. Dealer inspected and answered that “this is normal.”

Vehicle unexpectedly downshifted and service now light came on. Speed was difficult to control as the vehicle would either rapidly decelerate or accelerate. Cruise control was unable to be used.

Truck began downshifting from 6th gear to 5th numerous times at highway speeds (60ish mph). Wrench warning light would randomly come on, Service Engine Soon light would intermittently come on, followed by the dashboard totally blanking out. In one day on a drive to work, it started shifting from 6th to 4th. On the way home the same day, it shifted violently from 6th to 2nd gear hard at highway speed. The occurrence was a big safety concern as it was raining out - almost skidded out of control. As the truck was being driven into the dealership, there was NO acceleration - just revving of the engine which could have caused a major accident while having to cross two lanes of oncoming traffic. They diagnosed it as follows: 108572 found DTCP0706, P0707, P1702 / 20107 CF / MB3Z*7A100*B Transmission Control Assembly / FL3Z*7A098*B Screen Assembly / 7-XT*10QLVC Auto Transmission Oil.

My 2017 2.7l 6 speed f150 frequently experiences a random downshift to 1gear at various speeds and then it shifts to 5th gear and then 4th gear and then it stays in 4th gear. Multiple transmission shops have noted that the lead frame and valve body are potentially responsible for the downshift because the previous generation 6 speeds had the same issue. No codes are populating when the downshift happens and no CEL or Wrench light come onto the screen. The only way to get the truck to shift properly again is to turn it off and wait a while and then turn it back on. This problem has been reproduced by independent service centers.

While traveling at approximately 75 MPH, the transmission downshifted one(1) speed for about 5 seconds, then upshifted back into high Gear. I briefly got a readout that said "seeking parameters." This is a 10 speed transmission, my assessment is that what it did was drop from the "overdrive" gear into 9th gear. It was a single incident and did not create a safety hazard but may be a precursor for future problems. The vehicle has roughly 65000 miles on it.

I was experiencing hard shifting in upper gears like 8, 9 and 10. At 118592 miles the Ford dealer told me the transmission needed to be replaced. I had them install a Ford remanufactured transmission. The dealer told me this reman should have all the upgrades of the latest transmissions. Reman number is JL3Z 7000L. At around 123000 miles I experienced the following. I had the cruise control set at 74mph. On an upgrade I felt a hard shift. I noted the transmission was in 8th gear. Then it shifted to 9th, 10th and then to 1st. The truck was suddenly slowing down for what seemed like 3 to 5 seconds before shifting into 10th. I did not hit the brakes. Cruise control was still engaged. Suddenly it repeated the shifting from 10 to 9 to 8 to 9 to 10 to 1st and then 10th. The wrench warning turn on and 10th gear was locked out. After cycling the engine off and on again I have not experienced this again. I did notice after the incident my vehicle had an oily residue on the exterior. I was traveling on a dry road with few cars around me and good tires. I did not consider it a safety concern until I read about the 6 speed transmissions experiencing this and the their safety concerns. What if someone had been behind me, what if the road had been slick, what if my tires had not been in good condition? I searched ford forums online and was surprised to find others as recently 2023 have reported exactly the same experience on 2018 F150. The fact that my transmission is supposedly what is in the 2025 concerns me. I waiting to get my truck back into Ford Service.

2017 F150 transmission 10R80 started failing at 80K miles and completely failed at 113K. Dealer was asked to inspect the transmission but they misdiagnosed it. It is available for inspection until it is returned to Ford as part of complete swap\core charge. In the beginning the hard shifting did not put occupants at risk. As the transmission continued to fail it did put occupants and others at risk. Is would loose power/not respond to accelerator. Hunt for gears, shift from high gears to low gears while moving. Shifting to 1st gear while traveling at 45 miles per hour. Several times it would start to move from a stop but then not continue to move forward (in heavy traffic) The dealer miss diagnosed the problem and severity at 90K miles. They told me the transmission would continue to have firmer shifts while it was relearning programing. The dealer diagnosed a complete transmission failure based on codes DTSC P0734 and P07F7 stored in the transmission control module (at 113K miles). Their recommendation is a new upgraded replacement transmission from Ford due to internal failure. Ford Motor has been contacted through the customer service number 800-392-3673. There were no visible warning/check engine lights in the beginning (80K miles). Symptoms included harsh/delayed shift and harsh/delayed engagement. 20K miles later (113K miles) check engine light said to check the owner manual but didn't display codes. Transmission started to severely/erratically hunt for gears. Shift to 1st gear from higher gears (5,6,7,8) with very harsh down shifts.
