Vehicle shifts extremely hard, appears to shift into neutral, loses power and slows way down while driving. This has caused numerous safety issues that could cause a wreck that results in injury or death. Multiple times while on the interstate or passing a vehicle the truck has slowed down 10-20 MPH. This causes vehicle backups on the interstate and could result in death while passing a vehicle in a passing zone. The TB published did not fix the issue and the class action lawsuit filed in IL has been going on for four years. There have been multiple complaints of this issue and should result in a recall. Additionally, the dealership charged me 8.5 hours to overhaul the main control valve body when the TB states a maximum of 5.5 hours.

The IWE was faulty. I got in my truck and put it in drive, then when I started to accelerate, a horrible grinding sound started (sounded like my tire had been taken off and the metal from the rims were dragging kind of metal sound). I immediately had to try and pull over, and checked to make sure nothing was falling off. I put it in drive again and it did not do it until I went to leave work. Then I put it in drive and it did it again, so I put it in park and then drive and it still continued to make the noise. I parked and started to look at forums on 2018 f150s and grinding noises and seen one that said if it is the IWE, then put it in 4wd and then switch back to 2wd and it should stop. I did that and that is the only way I could get it to not make the horrid grinding sound. I could tell that there still was something going on with the vacuum because of how it drove, but I could actually drive without it sounding like it was going to fall apart. There were no warning lights that had come on when I was having the issues, and I ended up replacing the part at home. I should still have the original IWE at my house, but apparently this is a very common problems with these trucks.

Bought new in February, 2018. Vehicle has the 3.5L EcoBoost with 10-speed transmission, currently just over 50,000 miles, regularly maintained with Ford service providers. Since ~48,000 miles, when the engine is cold it occasionally produces a grinding noise at take-off or low speeds for 10-30 seconds or until ~35-40MPH when it stops, usually with a thud or a crunching sound, and it doesn't happen again once the engine is warm. It gets worse as you apply the gas, and the RPM sticks when you let off like it can't shift up or down. Ever since they did the transmission reprogramming a couple of years ago it's gotten BAD. Since then, when the engine is warm it's occasionally really rough when shifting up or down: the RPM will stick high or low for a second before thudding into the next gear with a jerk, to the point I can tell it's coming and can brace for it. I've complained about it to Ford, but nothing was resolved. "It's just one of those things." At 37,000 miles the internal transmission sensor that tells it to shift up or down failed (according to Ford), so it had become a manual transmission, shiftable only via the "Manual" option on the gearshift and the thumb rocker. That was fixed at Ford's expense, but the grinding is new, since ~48,000 miles (and I'm getting close to the end of the powertrain warranty). Ford couldn't replicate it when I brought it in (I thought it was a bad wheel bearing until I saw the RPM sticking this last time) because it doesn't always happen. Now that it's happening again with more frequency, they gave me an appointment three weeks out...hopefully it will live that long (and they figure out what's wrong with it).

Transmission slips when cold or hot. Had fluid flushed and filled and situation has gotten worse. Transmission shop said the valve assembly is defective and will cost $1,500+ to repair.

- Lapeer, MI, USA

2018 Ford F-150 Platinum has had and continues to have transmission issues even though the truck has been taken to be serviced for the same condition 4 times. This vehicle has the 10 speed automatic transmission. The first sign of transmission troubles was a loss of power while shifting from 3 to 4 gear. This was reported for service and technicians replaced the valve synchronizer and the clutches which looked worn and metal deposits were detected on the fluid. This problem disappeared for a while but started again slowly increasing as time passed. It was taken again to the shop and again the valve synchronizer and clutches were replaced again. This time the problem continued but other problem-??s arose including heavy knocking while shifting, jerking and hard shifting. We have taken the truck in for servicing and problems continue and Ford is not responding indicating that the unit did not show the problem reported.

- Guaynabo, PR, USA

My 10-speed transmission in my Ford F-150 is experiencing gear slipping, harsh shifting, jerking, sudden accleration, hesitation problems, and general loss of power. It started doing this at roughly 60,536 miles and Ford and the dealer refuse to assist with the current issue due to the vehicle being out of warranty. The dealer told me it would cost an out of pocket fee of $8,000. I have changed the transimission fluid my self and the vehicle continues to run above 245 degrees with a check engine light. The fault that I continue to see is a powertrain failure. After taking it in for a service to get my TCM updated, the technicians said it was up to date and there was nothing else they could do for it. My service history is as follows: March 15, 2022 when the dealr told me I needed a new front differential, November 28, 2022. Dec. 10, 2022.

- Killeen, TX, USA

The 10R80 transmission in this truck has hard shifting and finally at 120,000 miles began shifting from 7th gear to 1st gear while driving on roadways. The truck would lose power has hesitation like the gears slipping and hard downshifting. Dealership stated the Drum Clutch Basket had failed and requires a new transmission. Unknown to me the vehicle also had the motor replaced at 62,000 miles due to "oil consumption" issues. Ford has issued multiple TSBs in regards to these issues. The hesitation is so bad that the vehicle looses power and can happen at any time such as merging into traffic. The downshifting causes significant jerking of occupants.

- Eden, MD, USA

My 2018 Ford F150 is having problems shifting into gears and will disengage from gear while trying and rev up the engine until I take my foot off of the gas and the RPM's decrease and the transmission re-engages. Sometime this causes harsh shifting and sudden jerks of the truck. I notified the dealership and was put on a long waiting list but told to keep driving it. My place in line finally came up and was notified that the transmission was shot but the time frame to get a new transmission is 2 to 3 months. The vehicle is at the dealership right now so you would need to visit the dealership for inspection. I would say this item has put safety at risk since the vehicle will slow down while driving on the freeway. On the day I was scheduled to drop the truck off at the dealership, I had a hard shift and the check engine light finally came on.

- Sumner, WA, USA

The 10 Speed transmission has adaptive learning software. The transmission miss gears and lurches forward as if to be struck from behind. When the truck is in the higher gears the transmission disengages and acts as if in natural. There are times when the transmission shifts from 8 to 1 causing the vehicle to "buck". This is a serious safety issue that Ford has no plan to correct.

In October 2022, I began noticing while driving slight jerking, hesitation and apparent engine or transmission noise that appeared that my truck wanted to accelerate of when idling to a stop. A service light did come on at this point. I took my truck in to Koons Ford in Falls Church Virginia and reported my observations and concerns to Service Advisor [XXX]. [XXX] advised me that his service technician could diagnose the issue, and that the fee for this diagnostic work would be $250. I paid this fee with my credit card, but still don't have a record of this payment as it didn't appear on the invoice I received when the catalytic converters were replaced. [XXX] advised me that the issues I reported to me at the conclusion of the diagnostic testing that I needed new catalytic converters. The issue persisted and subsequently told by [XXX] after bringing my vehicle back to the dealership for almost 3 days of diagnostic work that I now needed a new transmission. I had been driving my truck and experiencing jerking and stalling to the detriment of my safety and that of my wife and grandchildren. I had to wait almost 4 weeks for the catalytic converters to come in for the catalytic converter installment. I was never advised during the period I was waiting for the catalytic converters to come in that driving the truck posed a safety risk so I drove it, albeit on a limited basis, while waiting on the parts to come in. A service light did come on at some point after the catalytic converted was installed and I coordinated a time to bring the vehicle back to Koons and as I indicated previously, after almost 3 days of presumably Ford technicians evaluating my, I was advised I needed a new transmission. I only have 80K miles on this truck that I purchased in November 2018. I understand the F-150 trucks, and late model F-150 trucks including 2018s have been found to have 10 speed transmission issues. This was not mentioned in any of my conversations with Ford. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (F

- Alpharetta, GA, USA

This is a messed up known issue with Ford F-150 2013-2018 model years with intermittent/unintended 4WD engagement. The system would lose vacuum and cause the hub to attempt 4WD engage at speed with loud grinding noise. Dealer for longest time could not/would not properly diagnose until I physically brought in the service bulletin. Ford-??s fix is to seal the vacuum hose and disable 2wd. And run AWD 24/7. #1 - lost 3-4 mpg average #2 - wore out the wheel bearing at 45,000mi. That was a $750 repair. Totally unacceptable!

- Pella, IA, USA

My truck has been shifting hard into 3rd gear in the mornings when the transmission is cold. I have reported to ford and a fix was attempted but nothing got better. This morning while taking my kids to school the 10 speed automatic transmission downshifted from 7th to 2nd gear while going 45 miles per hour. It reved the engine super high and slowed the truck quickly. It feels unsafe and I'm scared to put my family in my truck.

- Huntersville, NC, USA

The transmission skips gears. It shifts from 1 to 3 and 3 to 5 skipping 2 and 4 gears and I took to dealership and they said it-??s normal. When it shifts from 3 to 5 it-??s jerks all the time and it-??s not a smooth shift like every other shifts so there-??s something wrong with transmission or software. Recently I had issues while driving on freeway around 70-75 mph the truck was on 10th gear and it automatically shifted to 1 and then 5 then 6 then 9 and then shifted to 10. It happened like 2-3 from when I had this truck. When it did that it lost acceleration momentarily. Feel really unsafe when it does that because it can cause a wreck. The truck don-??t have engine light on but it definitely have some transmission issues and dealerships doesn-??t respond as there-??s no codes and I have extended warranty and dealership wants to charge me money for inspection. Please review my concern.

- Wesley Chapel, FL, USA

Transmission slips in and out of gear while in operation. When started, the truck will slip into neutral as it is driven. Makes it hazardous when merging into traffic or trying to pass as the transmission will slip without warning.

- Saginaw, TX, USA

Transmission goes slamming into gear on downshifts from 10 to 8 and 5 to 3. Terrible smoothness and it feel like the drive train is getting huge shock each time this happens. Upshifts from 3 to 5 are not smooth either under normal driving conditions
