2017 FORD F-150 Complaints

Noticed 6months after purchase on our way to Juneau Alaska from Arizona. I was driving my 2017 F150 and pulling a 8’x12’ toy hauler trailer on freeway doing 65 mph, I merged lanes to get off the freeway on off ramp. I took my foot off the accelerator got about half way down ramp and the transmission did major downshift to like second gear. Didn’t know what to expect so I just changed it from tow haul mode to drive mode on the end of the shifter handle. It seem to make it the rest of the way to Juneau Alaska. Just thought it was a weird one time thing. Didn’t really have any issues again till about 2022. I was driving in Juneau doing 60mph with my wife , mother and father in-law in the back seats and experienced it again, a major downshift not sure to what gear, it really threw all of us forward and luckily no one was behind me at the time or I would have been rear ended. Very scary to be driving on the road. Also noticed a couple more times when it did that there was nothing, no acceleration on the gas pedal. It seems to come and go. I took it in to the only place that repairs Fords here where I live. My five year factory warranty expired, I had a eight year extended but they would not cover the expense because they are not a official Ford dealer. I paid $1,834.38 to have the main control MB3Z-7A100-A part in the transmission replaced with filter, fluid replaced to at the same time. It seem to have fixed the high speed downshift for now, but noticed at slow speeds on deceleration letting my foot off accelerator I noticed it slips from like third to neutral and if I go to re-excelerate it slips back up to gear it left. There needs to be a National Recall on these Transmissions just like the 2014 F150’s. The Dealers are still using the same parts and build of these transmission’s as they did back then. Please put out a recall because after years of this issue it sounds like there are thousands of others dealing with this issue.

For the 4th time I am driving my truck, unexpectedly out of nowhere the transmission shifts, tires lock up, I am perked into the steering wheel and can't accelerate over 15 mph. Cars forced to dodge around me, horns blowing and I have no choice other than creeping on side of road until I decides to move. Please do something about thus hazard before something more serious happens

On [XXX] while driving at 70mph on [XXX] my 2017 F-150 began to shift into multiple gears causing the computer to shut down the trans causing me to coast from the center lane off to the shoulder. the truck shut down. and would not allow me to shift until the computer reset and then allowed me to go home. This happened again on Friday [XXX] leaving me stranded for 20 min in the center turn lane in Berea Ky. I Called the local for dealer who advised they had never seen this issue. I called Ford Customer Care and filed a complaint. on April 7th i took it to Richmond Ky AAMCO Transmission. They advised there is a TSB (technical service Bulletin on the LEAD Frame. The Lead frame houses all the electronic components to the shift solenoid plate. this frame unit is the culprit. and gets dirt between the solenoid electric pigtails causing shorts which causes the trans to freakout. Needless to say it cost me 1600.00 to get this issue fixed. they replaced the lead frame put in a fam spacer that protects the the sominoid connections, the also replaced the solenoid valve plate.
