Transmission shifts sometimes with really bad harsh jerks. at speeds below 50mph most of the time when pulling my boat trailer. this has happened several times in the last several months.
Transmission make a loud bang when starting vehicle. upon acceleration at highway speeds when transmission shifts from 10th to 6th gear it it so violent it feels like i have been rear ended by another car. sometimes transmission will have a 3-4 second delay to go into reverse and then makes a loud bang when reverse engages. spermatic hard shifting. all these problems started at about 20,000 miles.
This has happened 3 times. while traveling on the freeway the truck goes into neutral and won't shift into gear i have to coast to the side of the road and re-start the vehicle and go again. this could be very dangerous traveling at high speeds on a busy freeway with no shoulder.
I recently bought a brand new 2019 f150 at larry h. miller ford draper. and within a little over a month of owning the truck the transmission is now giving me problems. just recently took it in to the service department, left it there all day only for them to tell me that everything is fine. and since i've had it back the problems have been getting worse. i've been experiencing problems with the transmission skipping gears (2nd and 5th). staying in gear too long. it doesn't shift down properly, so it takes a lot of power to make a full stop. as accelerate it goes from 9th to 8th, then down to 7th then back up to 9th. and i really have to accelerate it to even shift gears.
The 10 speed transmission is inconsistent in shifting especially when cold ... also grabs and clunks if slightly rolling backwards when moved to drive (inconsistent). creates unpredictable driving situations.
While driving the vehicle on a city street it started to accelerate on it's own and i had to slam on the breaks because of it doing that. again one december 20th 2019 it did it again. i dont know what's causing it to be doing that but i've taking it to the dealership and nothing can be found wrong.
On tuesday 11/5/19, we were traveling on a highway at around 45 mph when i decelerated to make a right hand turn onto a city street. i had accelerated back up to around 30 mph when i cross over a relatively smooth railroad crossing at a slight left hand turn. immediately the information center on the console start displaying multiple alerts and the vehicle started decelerating. while the engine did not cut off, there was no power to the powertrain and eventually we rolled to a stop on the side of the road. the vehicle continued to fire alerts. the only way to stop them was to turn the vehicle off. the messages still fired so i opened and closed the door. i restarted the vehicle with no problem and the alert messages had ceased. i drove the vehicle back to the house (approximately 4 miles) at highway speed with no issue. we took the vehicle to the dealership then next day (26 miles) with no issue. fortunately, our ford pass app had captured all the alerts and, after a couple of days, the dealership replaced a gas pedal position sensor. we picked the truck up on friday and it worked fine until the next day. we were decelerating from highway speeds on the highway to turn left onto a side road. we hit a small hump where the side road meets the highway and again the alerts starting firing and the truck lost propulsion. again, the engine did not turn off and the only remedy was to turn it off and back on. we plan on taking the vehicle back to the dealership but would like for ford to assess this problem as it seems to be beyond the dealership's capabilities to fix the issue. since several of the alerts represented loss of safety functions including brakes, traction control, powertrain failure, and others we feel this issue represents a safety issue that ford needs to diagnose and fix. several of the f150 forums have shown other users having the same issue.
I was driving down my block got to a stop sign as i was getting ready to pull up the truck would not move. the engine wouldn't rev and the transmission wouldn't shit. i decided to shut the truck off and wait a little still nothing. the only way to get the truck to move was in reverse.
