Timing chain loose has to be replaced

- Church Hill, TN, USA

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.

When shifting the truck into gear the lights such as the parking, driving, neutral, reverse and lower gears lights as well as the lights showing which gears the trucks shifting into do not light up! Therefore, you cannot tell what gear the truck is currently placed into. Also, if the lights do light up, they flicker very erratically, and the truck will change gears on its own. When driving the vehicle, the truck will just suddenly change gears and makes a hard shift into lower or higher gear or gears which is extremely dangerous. This makes the truck feel like I've been hooked up to another vehicle that is trying to snatch me backwards. I was driving on the highway the other day and the truck went from 6th gear doing over 70mph to all of a sudden downshifting and dropping down to 40mph on the highway. I thought the engine and transmission were both going to explode on me and cause an accident. This was extremely terrifying and if I didn't keep my cool it could have easily caused a wreck. Most people would have freaked out had an accident. The truck barely made it home because of the gears shifting all over the place and the truck wanting to lose power and shut down. This is extremely dangerous and the representative I spoke to from Ford agreed that considering the mileage of the truck and with the recent recalls concerning transmissions being recalled for the exact same issues that my truck is experiencing that I needed to call you guys and get my tuck added to the Ford F-150 recall list for the transmission issues ford trucks have been having. The Truck is a 2016 Ford F-150 XLT. This is the case number provided to me from Ford to give you Ford Case # CXH03020325

The transmission 6R80 is absolutely horrible, a part called the lead frame is all over youtube on how to fix it at home. the transmission causes slam shifts, missed shifts, or nothing at all. 2nd to 3rd, 3rd to 4th, and 4th to 5th. When slowing down again hard shifts back down again. local mechanics say they don't want to change transmission fluid as it could do more harm then good. I called my local ford dealership and was offered to bring it in where the test would show either a transmission fix or a full replacement which is absolutely crazy to me, Ford should be held liable for these mistakes because it should be fixed with a piece of Styrofoam over the sensors, and then transmission fluid changed. But ford knows for all of that and all of the 6R80 transmissions they've put out is an astronomical number. This is horrible that its happening to a very large majority of these transmissions and nothing from ford.

transmission suddenly downshifted causing vehicle to almost stop locking up the rear end momentarily scaring all passengers and almost causing an accident. this occurred several times. the vehicle does other weird things as well. dealer says it is lead frame issue wants to charge 1800 dollars to fix. I looked up info on how the 11 thru 13 models have recall for the exact issue and same transmission. why then wouldn't a later vehicle same transmission exact same issue be cover as a recall as well? This keeps reoccurring putting lives at risk it also looses power making so the vehicle will not move out of traffic the check engine light sometimes comes on stating trans issues the wrench light on the dash illuminates dealer as admitted it needs a new lead frame 2011 thru 2013 had recall for exact same issue has been happening for several weeks no warning just all of the sudden each time which is getting worst

- Orem, UT, USA

Driving vehicle after about 20min of run time the transmission downshifts hard and all or most driver assistance feature warnings alert they are not functioning. Engine RPMS raise but vehicle does not move. Vehicle got stranded on busy road during rush hour with no ability to move on its' own. Check Engine light and other warnings on dashboard. Later diagnosis with a scan tool and pin point testing verified that the Lead Frame inside the transmission has failed at 80k miles. More concerning than early failure is the safety problem this poses. Braking, steering, and propulsion are all affected significantly! Once vehicle is stopped and put into park it won't shift or start again. Also if the vehicle is in park when symptoms are present any input on the gas pedal raises and holds the engine RPM at redline/rev-limiter for approximately 5 seconds. TPS Sensors and throttle body are all functioning properly.
