Ford F-150 10-Speed Transmission Subject Of New Lawsuit

A new class action lawsuit asserts that the 10-speed 10R80 automatic transmission equipped in Ford F-150 models can cause "life-threatening" issues due to "harsh shifting, jerking, hesitation and slipped gears." The lawsuit includes a number of 2017 to 2019 Ford F-150 models in Illinois.

According to one plaintiff in the lawsuit, the 10R80 10-speed automatic exhibits a loud "clunk" or "bang" noise when starting the engine on his leased 2018 Ford F-150 XLT 3.5L EcoBoost, just five months and 6,000 miles after acquiring the vehicle. The plaintiff also asserts that the transmission will hold gears for too long, and exhibit power loss while shifting during warmup or when cold.

Apparently, at one point the plaintiff’s Ford F-150 wouldn’t even accelerate or shift, instead displaying the message "drive mode not available" in the dash. After determining the vehicle was in limp mode, the plaintiff pulled over to disconnect the battery and reset the onboard computer.

What’s more, the lawsuit says that some owners have suffered whiplash due to the poor shifting quality of their Ford F-150.

So far, Ford has issued two technical service bulletins to address the issue, including TSB 18-2079 and TSB 18-2274. Both confirm the 10R80 10-speed transmission can exhibit harsh or delayed shifts, as well as firmer than normal upshifts and downshifts. One possible explanation is that the "adaptive transmission shift strategy," which is intended to improve shifting quality, actually worsens the shift quality for several days after the adaptive strategy is reset as the computer relearns various parameters.

Meanwhile, the lawsuit says the adaptive transmission shift strategy does not address the 10-speed’s numerous other shifting issues.

Notably, the Ford F-150 10R80 automatic transmission was developed jointly between FoMoCo and General Motors. The transmission can also be found in the Ford Mustang, Ford Expedition, Lincoln Navigator, Ford Ranger, and overseas, the Ford Everest.

  • A truck that shifts so firm you can get whiplash..!!? Really, at no extra cost? Sign me up, usually I have to pay extra for trans modification and\or tuning to get that. The limp mode thing is not cool, but as for gear changes the more harsh the better.

    • 33.3%! You're wrong there! That's the snakey lawyer's personal take. After court costs, administrative fees, and all the other crap they'll charge you for, you would be lucky to get 50 cents. All these lawsuits that snakey lawyers win costs the consumers with higher prices. Just look at health care and prescription costs and thank a lawyer for outrageous costs.

    • I had serious and life threatening sudden loss of power issues. Between 10 and 20 mph, the transmission would shift down to 0 RPM causing the back wheels to lock and screech to a halt!! I was lucky I was never rear ended when it happened. I had only 60,000 miles on my new 2018. My new 2013 ALSO had sudden loss of power issues but not life threatening. After these issues with BOTH new Ford trucks, I traded it in for a Dodge. I’m DONE with Ford!!! Their vehicles are dangerous!!! If you can get rid of that truck, do it ASAP!!! It’s a death mobile!!!

  • Ok, I’m going to accelerate from 0-70 mph. By 70 I should be in 10th gear. On average that is a shift every 7 mph. I wonder why there are problems when it is all computer controlled. This learning program has been around for years and to me it is all marketing hype. I have bad driving habits doing hard acceleration and braking, so how the the learning program change shift patterns, etc?

    • When you accelerate and then let off the gas, it doesn't upshift and engine brakes hard....kinda blows.

  • I have this truck and I can tell you that the transmission isn't as good as the 8 speed I had in my 2014 Hemi. That thing was always in the right gear, this one has inconsistent hesitation and lethargy, for lack of a better description.

  • Owning two 2018 vehicles with this transmission, I can say that the one in my mustang GT acts funny sometimes, but has never been much of an issue, and the same trans in my F150 3.5 eco has had zero issues whatsoever. Both have drive modes, and both will change behavior dramatically as intended switching between some modes. "Whiplash" inducing? I call BS.

    • Agreed! 40K on my '17 lariet, zero tranny problems..... Some money grubbing lawyer looking for his/her 33.3%

        • And don't forget the Shyster lawyer will surely get HIS cut before you receive that $.50 settlement!

      • The same deal the Focus/Fiesta DPS6 DCT transmission, MOST of the "complaints" for this transmission were due to uneducated owners not familiar with a MANUAL transmission that is shifted AUTOMATICALLY, vulture lawyers were ready to get inside Ford's "deep pockets" by filing frivolous lawsuits, trashing Ford's reputation. There was a "legitimate" problem with the DPS6, had to due with defective oil seal allowing oil on the "dry" clutch discs causing Shudder. This was fixed by Ford long before all the lawsuits. I own a '13 Focus with the DCT, had clutch pak replaced Free at 53K miles, now have 83K miles and car is running SWEET!

    • 2018 f150 2.7 eco boost had the service refresh of the control module done and also bought a tuner am using the 87 obtained street tune its been like nite and day since I had the mods done transmission shifts 100%better now now I love this truck before I was ready to dump it get the service reflash done and get a tuner it worked 9n my truck

    • It’s not whiplash inducing. Just very irritating. Hearing the rear end clamk on a shift sucks. Do they still make manuals?

  • We have three Ford F-150 trucks... they do this. Ford Service can not ever create the scenario... there for the trucks are still undiagnosed.

  • I have an ‘18 F150 3.5; so far so good. A lot of people complain about feeling it downshift as you slow to a stop. Hell, I LOVE that!

    • Does that 3.5L V6 have the "chain driven" water pump? I am asking because I recently sold my '12 Lincoln MKZ with only 55K miles on it because heard that water pump on these vehicles starts to leak, the owner could end up in a world of hurt like...........needing a new engine, to the tune of at least $3K. I really LOVED that car, but hearing about this problem, sent CHILLS down my back. I wanted to unload it before there was a hint of a problem. Did Ford redesign the 3.5L that is in your truck? If so, than at least I would be in the market for another 3.5L V6!

  • I own a 2019 Mustang GT with the 10 speed transmission and 3:55 rear, manga ride suspension and virtually every available option. The car is simply awesome and so is the 10speed. Yes the first 1200 miles or so it did some wacky, even clunky shifts as it learned to shift according to the owners (me) driving habits. And maybe a couple of very loud/ harsh 3/2 downshifts approaching a traffic light. But all things considered the car is crazy fast and fun to drive. I’m sure there will be some defective units out there as there are with all significant new products. May I suggest that the folks experiencing the problems drive for 1200-1500 miles of break-in using every drive mode with both highway and around town driving so the PCM can learn. It is after all, a complex product that is operated by a computer interpreting the drivers input... hope this helps.

    • I own a 2019 Mustang GT with the 10speed and the Performance Pack 1 option. (larger radiator, Brembo brakes, stiffer front springs, staggered wheels) Its fun to drive, yes!! trust me, this thing makes use of every bit of horsepower and it is fast!! I drive hard just like you but this adaptive learning thing is crazy. I think mine has a learning disability! It never keeps what it has learned. It goes through its cycle, gets everything dialed in and then a week later, it forgets and goes back into class after learning some bad habits. The worst is being in 10th gear at 40mph and I go to pass somebody and no response. I literally have to put the pedal to the floor to force a kickdown or go to the paddle shifters and manually shift it. Not that its a bad thing but if it learned to it by itself, why am I reminding it later on???? I brought this up with the dealer a couple times but of course, as always, if it doesnt do it with them in the car, they cant take it apart and investigate further. I took the tech to the side off the record and asked him whats the deal with this and his answer was "there is an issue, there are problems, 1st and 2nd gears burn up quite easily especially if you drive in the Sport and Sport + modes and then go back into normal mode, but you have plenty of warranty left on it, wait until the transmission completely fails and then bring it in" I knew exactly what he was talking about because I went into those modes just to see the difference and when I did go back into normal, the car drove like it was completely lost. the shift pattern was all over the place.

      • I wonder if these transmissions would have these problems IF GM had stayed out and just let Ford engineers due the designing. Seems like most of the stuff that GM designs turns out to be a "pile" of turds. The jury is still out on the 8-speed DCT that's in the C8 Corvette, will have to wait and see! The only GM vehicles that I trust are the "Korean Jukeboxes" like the Chevy Sonic (which is DONE come Oct, because of poor sales)!
