I just bought this 2017 f150 from deacon jones Ford and 4 months later I'm having transmission issues. After driving for a little distance, when I stop and start driving again I notice the rpms go crazy and it won't shift out of 1st gear and all of the sudden it goes to 5th gear and jerks and goes back to 2nd gear and slowly goes up. I just have the transmission fluid changed at the dealership and two weeks later this starts. I tried researching it and notice Ford has some issues with 2017-2019 f150 transmissions. So I looked to see if this truck had already been inspected with the same issue and if it was fixed. I'm about to go on a 10 hour drive to tdy to a military base and I need to know if it's safe to drive and won't go in limp mod. Thanks joseph.
Original problem was transmission slamming into gear and slipping when accelerating. The truck was kept at agency for 21/2 weeks. Service manager told me that Ford instructed him to quit working on it. Problem of slipping still exist and recently the vehicle jumped out of gear when I was merging onto the interstate, I do not feel safe driving this vehicle.
4500 miles on vehicle, never towed anything, only normal city/highway driving, no long trips ever taken. Was turning left at intersection and transmission seemed to slip, truck still made it through, I then noticed that a yellow "wrench" light came on, I assumed this was for my upcoming 5k mile oil change. I didn't think much of the "slip" and assumed it was an anomaly. I then got onto the highway and noticed the truck was behaving strangely, power was inconsistent, I attempted to put it into cruise control and it refused to activate. I got off of highway and turned left at an intersection, starting from a complete stop the truck lurched forward and then slipped out of gear and stalled out in the intersection. If a car was coming I would have easily been struck. I let it sit for a few seconds and then the transmission finally got into, and stayed in, first gear. At first it went into gear and then slipped out of gear. This "wrench" light was apparently a limp home mode, another complaint, besides the stalling, would be the fact that this little yellow wrench light does nothing to warn me that the truck is actually in an impaired state, a "limp" mode. I work in the aerospace industry and this would never be tolerated, a function that hampers the normal performance of your vehicle should be easy to recognize as a warning, a little yellow wrench looks like a service light.
