Downshifted while driving- vehicle locked up temporarily

- Humble , TX, USA

I was driving the truck and the wheels seized up. Making me skid. Luckily I wasn-??t driving fast. So I looked up what could cause this and it stated it was the lead frame sensor. Before I could get it into the dealership for repairs the truck downshifted several more times. I was able to find the repair online. Unfortunately the dealership tried to sell me a new transmission. I relented and told them what the issue was due to investigating in F-150 chat groups. The rear collision sensor went off. Also the shift sensor went out as well.

Transmision issue.. downshifts while driving. Then stuck in lower gear when accelerating. Need to come to a complete start.. Shift to Park.. then back to drive to clear. Feels very unsafe when it happens. Trouble codes confirm its a shifting issue. The wrench on the dashboard lights up momentarily.

The rear Axel is starting to fail. This vehicle has not been used in a work/commercial environment. The rear axel has a loud humming noise, it was diagnosed as a bad spider gear and bearing. This is also causing major limitations on the initial speed up of the vehicle. This is causing a drag feeling when accelerating into a highway. It-??s a 3 thousand dollar rebuild. This is extremely weird, a drivetrain Axel should not fail under regular driving conditions.

While driving the truck jumps back and forth between Drive and Manual multiple times and then goes. Happens occasionally and has been going on for about a week. Then today, it did it again and all gauges flicked on and off and jumped between gears. It first happened on the highway doing 70mph and it's like it dropped down to first gear and throws you forward.

While driving my truck the transmission gear lights on the dash will begin to flash and the transmission will downshift very hard causing the rear end to lock up. This has happened three times now at traveling at a high rate of speed on the interstate (roughly 60-65 MPH).

Transmission gets stuck in 3rd or sometimes 5th gear when in Drive. Shifting to 1, 2, or M does nothing; shifting from Neutral to Reverse or Drive creates a large clunk and lunge. It seems to be the same issue as the 2014 F-150 & Expedition 6R80 transmission recall and is so common that it took no time at all to find out what my problem likely is.. This is the 5th time this has happened. Two times were when pulling out onto very busy roads, once in a parking lot, once in a field, and once turning into my alley; some incidents were years apart. If it were to happen again when I needed 1st gear to avoid being hit, I would not have the power for needed acceleration or to make a proper maneuver. It also acts very funny when it happens and creates a very large distraction from driving. When I was able to get back off the main road, it seemed like there was light smoke coming from under the truck so I shut the vehicle down in the middle of a smaller road, which was dangerous enough. I have less than 30,000 miles on my truck and am very maintenance minded; this should not be a worry I should have to have. This appears to be the result of a defective part in the transmission called the "Lead Frame" and it is not easy to find a new one right now due to the excessive amount of them needing replacement.

When I was driving on the highway about 65 mph the truck abrubly downshift to 1st or 2nd gear causing the truck to dermaticly slow down. I am lucky there was nobody behind me because they could have rear ended me. The issue ended up being the transmission valve body harness which is apparently a common issue.

I was getting married and setting to go a getaway immediately after we wed. I got a tune up and go my vehicle read. After the tune up it the drive felt great. So me and my wife took to the highway, and as my vehicle began to accelerate the engine began jitter as I press on the gas peddle. The car would not go past 50 mph. As I kept my feet on the gas you can feel the whole car shaking, then the eco boost kicks in and it immediately accelerate at a high rate of speed and as attempt to control the speed by letting go of the gas. The vehicle shakes as it looses power and settles on 50 to 60 miles shaking until the eco boost kicks in. It was a two hour ride and I couldn't look back just pray. Through out the ride it was the same thing over and over again. My wife and I were in constant fear, because I felt due to the erupt increase in speed I was putting other motorist at risk. The engine light came on and a wrench symbol and tire symbol came on. The component or system that failed or malfunctioned involves the eco boost. It appears to be the same recall reference NHTSA # 24V-635 & Manufacturer: # 24S55. My vehicle presently has 78,000 miles on it and it should not be doing that. I have also looked at other problems with the 2016 Ford F-150 Ecoboost as being the web belt system and head gasket failure. However, whatever is the case anyone with this type of vehicle and experiencing the same thing is catastrophic the public safety at large and it cannot be ignored. Ford must correct this problem before someone end up dying as a result of this problem. Thank you for taking the time to read my story and I pray this may help you properly investigate my experience. I can have my truck available for anyone from NHTSA to inspect. Presently there is no data regarding the problem with this particular vehicle.
