The Ford F-150 transmission lawsuit is actually a group of class actions filed in federal courts in Illinois, California, Massachusetts, and Virginia, along with a proposed national class action in British Columbia, all alleging that the 10R80 10-speed automatic transmission in 2017 and newer F-150s and related vehicles shifts harshly, hesitates, and can lose power. As of mid-2026, none of the class cases have settled or been certified, though individual owners have won substantial recoveries under state lemon laws.
What Owners Say the Transmission Does
The complaints describe a consistent set of behaviors. Trucks jerk and lunge between gears. Shifts arrive late, or land hard enough that drivers report whiplash. Some owners say the transmission gets stuck in a single gear. Others describe a loud clunk on startup, or a complete loss of power during acceleration, which the lawsuits characterize as a safety hazard at intersections.1ClassAction.org.

Ford’s own Technical Service Bulletins point to mechanical causes. TSB 24-2254 identifies axial movement of the CDF clutch cylinder sleeve, which allows hydraulic circuit leaks and produces harsh or delayed engagement.2NHTSA. TSB 24-2254 An earlier consolidated bulletin, TSB 22-2428, laid out a tiered repair path escalating from software recalibration through valve body overhaul to full CDF clutch cylinder replacement.3NHTSA. TSB 22-2428 A separate technical analysis identifies a second failure mode: the E clutch pressure passage in the 10R80 runs close to bolt holes for the electronic auxiliary fluid pump, and the thin wall between them can crack, causing pressure loss and clutch damage independent of the CDF drum issue.4Transmission Digest. 10R80 E Clutch Damage Cause and How to Fix
Which Vehicles Are Covered
Ford began installing the 10R80 in the F-150 with the 2017 model year and later expanded it to the Expedition, Ranger, Mustang, Transit, and Lincoln Navigator. The class actions cover 2017 and newer vehicles equipped with that transmission.5Wallace Miller.

How Ford Has Responded
Ford has not publicly conceded a systemic defect. Its service bulletins instruct dealers to tell customers the truck uses an “adaptive transmission shift strategy which allows the vehicle’s computer to learn the transmission’s unique parameters and improve shift quality,” and that after a reset, drivers may experience “firmer than normal upshifts and downshifts for several days” during relearning.7NHTSA. TSB 23-2123 Plaintiffs allege Ford has used this “adaptive learning” framing to deny warranty claims, telling owners that rough shifting is normal behavior.1ClassAction.org.

Status of the Class Actions
The furthest-along U.S. case is O’Connor et al. v. Ford Motor Co., No. 1:19-cv-05045, in the Northern District of Illinois. Plaintiffs moved to certify the class in September 2024, and that motion is still pending.5Wallace Miller. Ford Transmissions The case has survived several attempts by Ford to knock it out. In March 2025, the court rejected Ford’s move to dismiss the plaintiffs’ Magnuson-Moss Warranty Act claims. In January 2026, Judge Jeffrey Cummings denied Ford’s motion for judgment on the pleadings on a Massachusetts consumer-protection claim, finding the plaintiff had “sufficiently stated an independent claim” under Chapter 93A.8Ford Authority.

A parallel consolidated action, Miller et al. v. Ford Motor Co., No. 2:20-cv-01796, has been pending in the Eastern District of California since September 2020, with Lieff Cabraser Heimann & Bernstein and Capstone Law appointed as interim lead class counsel.9CourtListener. Miller v. Ford Motor Co. Fact discovery is still ongoing and class certification has not yet been briefed. Related cases are moving through the District of Massachusetts and the Eastern District of Virginia; a judgment was entered in Dolan v. Ford Motor Company in Virginia in June 2026, though the terms are not reflected in available records.10CaseMine. Dolan v. Ford Motor Company
In Canada, Charney Lawyers PC filed a proposed national class action in British Columbia Supreme Court in April 2025. A case management judge has been assigned and a conference was scheduled for February 2026 to set the certification hearing date. The case has not been certified.11Charney Lawyers.

Because no class has been certified and no settlement reached, there is nothing to file a claim against yet. Owners waiting on class relief are, for now, waiting.
Recalls and What They Do and Don’t Cover
NHTSA’s biggest recent action on F-150 transmissions is not about the 10R80. Recall 26V237, announced in 2026, covers 1,392,935 F-150s from the 2015–2017 model years equipped with the older 6R80 six-speed transmission, where degraded electrical connections in the transmission lead frame can cause unexpected shifts to neutral, unintended upshifts or downshifts, and rear-wheel lockup. The recall carries a “Do Not Drive” advisory, and Ford’s remedy is a powertrain control module software update, with lead frame replacement for trucks that showed related diagnostic codes. Dealer notifications went out in April 2026, and owner notices were scheduled for July 2026.12NHTSA. Recall 26V237 If your truck is a 2017 or newer with the 10R80, this recall does not apply to it.
A much smaller recall, 25E070, covered 34,481 vehicles across several Ford and Lincoln models that received remanufactured 10R80 transmissions as service replacements. The defect was a missing bearing that could prevent the transmission from properly engaging in park, traced to an assembly error at supplier ATC Drivetrain Inc.13NHTSA. Recall 25E070
What Owners Can Do Now
Individual lemon law claims have produced meaningful recoveries while the class cases work through certification. In one reported case, attorneys at Knight Law Group obtained a $165,000 settlement offer for the owner of a 2022 F-150 that had been purchased for roughly $65,400. The truck exhibited gear slipping, lurching, transmission fluid leaks, and a complete transmission pump failure in January 2024 that put it in the shop for about a month, with roughly two months of repair time overall. The offer amounted to more than two and a half times the purchase price.14Knight Law Group. Ford F-150 10 Speed Transmission Lemon Law Settlement Offer Some plaintiffs’ attorneys argue that individual claims frequently yield higher per-owner recoveries than a class settlement would.
If you are still under warranty, document every dealer visit and keep repair orders. Ford’s service bulletins direct dealers to try software reprogramming first and escalate to valve body or CDF cylinder work, so the paper trail of what was done, and what did not fix the problem, is what a later lemon law or warranty claim will rest on.
What Out-of-Warranty Repair Costs
For owners past warranty and outside any recall, costs run high. Dealer quotes for a full transmission replacement typically fall between $8,500 and $11,000, with parts alone around $5,800 to $6,250 for a Ford remanufactured unit and labor of roughly $2,600 or more. Independent shops have quoted about $6,700 installed for a third-party rebuild. Software updates and valve body reprogramming run $250 to $450, and a full rebuild at an independent shop $4,500 to $6,500.15Athens Ford Service. F-150 10R80 Transmission Repair Back-orders on replacement transmissions have at times pushed owners toward remanufactured units.
Where Things Stand
The Illinois case is the closest to a class certification decision. The California case is still in discovery on an amended complaint. The Canadian case has not yet reached its certification hearing. No settlements have been announced anywhere. In the meantime, an individual lemon law or warranty claim is the only path with a defined timeline, and it does not require waiting for the class litigation to resolve.
