Ford 10 Speed Transmission Lawsuit Update for 2017–2020 F-150s
Table of Contents
Is there a Ford 10-speed lawsuit? The short answer
Yes, but it is no longer a class action you can join. O’Connor v. Ford (N.D. Ill., No. 1:19-cv-05045) was filed in 2019 over the 10R80 10-speed in 2017–2020 F-150s. In September 2026, the judge denied class certification.
As of our September 28, 2026 check, there is no settlement, no claim form and no certified class. Find your situation below.
- 2017–2020 F-150 with harsh shifts: start with Ford’s bulletin and your repair options.
- 2021 F-150: you were never in this case, but check the park-system recall in the table.
- 2015–2017 six-speed truck: the big 2026 downshift recall is yours. The lawsuit is not.
- Truck skipping or stuck in gears: see our guide to an F-150 10-speed that loses gears.
Other issues by model year are in our F-150 problems by year guide.
ℹ️ Safety Note: Harsh engagement, sudden downshifts, and a transmission that won’t hold Park are safety concerns, not just legal ones. The information here is for general understanding. If your truck shows any of these, have it inspected by a qualified technician, and don’t wait on a court case to do it.
Is your F-150 part of the 10-speed lawsuit?
No F-150 owner is currently a class member, because the court declined to certify any class. Here is who the case was about.
| Your F-150 | Transmission | Where you stand | Applies To |
|---|---|---|---|
| 2017–2020, IL, CA, MA or NY | 10R80 | Was in a proposed class. Certification denied Sept 2026 | Court’s class definitions |
| 2017–2020, other states | 10R80 | Never in a proposed class | Same |
| 2017, six-speed | 6R80 | Not in this case | Some 2017s used the 6R80 |
| 2021 and newer | 10R80 | Outside this case | Case covered 2017–2020 only |

Model year and transmission
Some 2017 F-150s left the factory with the six-speed 6R80. Check the transmission code on your door-jamb sticker before assuming either way.
Your state
Plaintiffs asked for four state classes: Illinois, California, Massachusetts and New York. Now no class exists in any state.
2021 and newer trucks
These trucks also use the 10R80, but this case never covered them. Ford’s bulletin 24-2254 addresses harsh shifting on 2021–2022 F-150s built on or before 15 August 2022.
Where the O’Connor case stands in 2026
The case has moved slowly since 2019. These four 2025–2026 rulings shape where it is now.
Rulings so far
- March 2025: federal warranty-law (Magnuson-Moss) claims were allowed to continue.
- January 26, 2026: a Massachusetts consumer-protection claim survived Ford’s challenge.
- February 4, 2026: the court ruled on both sides’ warranty experts.
- September 2026: class certification was denied. Law360 and Mealey’s report two reasons: a class-action waiver in Ford’s warranty blocked the warranty claims, and the other claims didn’t show a common defect with a common cause.
📋 On the Record: In the February 4, 2026 order, both sides’ experts looked at 2017–2020 10R80 F-150 warranty data.
- Ford’s expert found 95.3% of 2017 and 93.3% of 2018 trucks had no harsh-shift warranty claim in their first 60,000 miles or 60 months.
- The plaintiffs’ expert found 20% had at least one visit for a transmission claim.
Ford denies any defect. Status checked September 28, 2026.
What the denial means
The denial doesn’t mean the court ruled the transmission is fine, and it doesn’t mean the court found it defective. It means owners won’t be compensated as a group through this case.
What Ford’s bulletins say about harsh 10-speed shifts
Ford’s bulletin for the 2017–2020 F-150 names a specific internal cause for harsh and delayed shifts.
The CDF drum explanation
📋 On the Record: Ford TSB 25-2126 (31 March 2025, replacing 25-2018) covers 2017–2020 F-150 and 2018–2020 Mustang with the 10R80. It lists four conditions: harsh engagement, delayed engagement, harsh shift and delayed shift. It also lists warning-light codes including P0751, P0731 and P2700. It says these may be due to axial movement of the CDF clutch cylinder sleeve causing hydraulic leaks.
🔍 Why It Happens: The CDF clutch cylinder routes fluid to clutches the transmission applies during gear changes. If its sleeve slides out of position, fluid leaks between circuits. A clutch then applies late or hard, which you feel as a slam or a flare between gears.
Read Ford’s bulletin 25-2126 or our full breakdown of 10-speed transmission problems on the F-150.
2021–2022 trucks have their own bulletin
Bulletin 24-2254 covers 2021–2022 F-150s built on or before 15 August 2022. The 10R80 MHT is excluded. A bulletin isn’t a recall: Ford’s 2023 bulletin says repairs follow your existing warranty coverage, and bulletins don’t change warranty limits.
Is the big F-150 transmission recall about your 10-speed?
No. The 2026 recall of 1.39 million F-150s, 26V237, covers 2015–2017 trucks with the six-speed 6R80. It does not cover the 10R80.
| Campaign | Issue | Applies To | Status (Sept 28, 2026) |
|---|---|---|---|
| 18V213 / 18S09 | Park pawl roll pin may be missing | 2017–2018 F-150 10R80, built Oct 2016–Mar 2018 | 2018 recall; check VIN |
| 26V402 / 26S48 | Park pawl may engage while moving | 2021 F-150 10R80, built Jan 8, 2020–Oct 8, 2021 | Open; remedy expected Q2 2027 |
| 25E070 / 25SB3 | Reman unit may lack T10 bearing | Reman 10R80s fitted to 2017–2021 vehicles | Open |
| 26V237 / 26S28 | Unexpected downshift | 2015–2017 F-150, 6R80 only | Open, not a 10-speed recall |
Recalls that do cover 10R80 trucks
If your 10-speed was already replaced under warranty, the remanufactured-transmission recall notice matters most. The replacement unit itself may be the problem.
⚠️ Watch Out: Until the 26S48 fix arrives, Ford’s recall page says to apply the electronic parking brake every time you park. That is the practical protection against rollaway while the software remedy is developed.
The 6-speed recall and probe that don’t
NHTSA’s downshift investigation summary was limited to 6R80 trucks. We cover that fix in our breakdown of the 26S28 six-speed downshift recall.
✅ Do This: Run your VIN through NHTSA’s VIN recall lookup. Then ask the dealer three things:
- Check Ford’s recall system for open 18S09, 26S48 and 25SB3 campaigns.
- Confirm whether any earlier transmission replacement was a remanufactured unit.
- Print the result on a repair order.
Repair now or wait for the lawsuit?
Don’t wait. With no certified class, there is no class-wide reimbursement for a repair you delay.
In warranty vs out
Ford’s standard powertrain warranty runs 60 months or 60,000 miles from the warranty start date. Many 2017–2020 trucks are now past it. Check your start date on the original invoice before you pay for anything.
What a CDF drum repair or replacement involves
Ford’s bulletin procedure can require removing the transmission. That is why quotes range from replacing an internal part to fitting a complete remanufactured unit.
💵 On these numbers: Costs shown are typical ranges, not quotes. Labour rates vary sharply by region and between dealer and independent shops, and parts pricing moves. Use these to judge whether a quote is in the right neighbourhood, not to predict your invoice.
💵 What It Costs: Ask for a quote that separates four items:
- parts: a CDF clutch cylinder, or a whole remanufactured transmission,
- labour hours for removing and refitting the transmission,
- fluid,
- programming.
Sourced ranges with their assumptions are in our F-150 10-speed transmission repair cost guide.
What to do now that there’s no class
Your options are now individual, not group.
Documentation that protects you
Keep every repair order, and make sure each one records the concern in your words, the codes found and the bulletin applied. That paper trail is what an individual claim runs on.
Lemon law and arbitration clauses
State lemon laws set their own limits on repair attempts and time windows, and many 2017–2020 trucks may be outside them. The class ruling also points to terms in Ford’s warranty that limit group claims. An attorney licensed in your state can tell you what still applies and what deadlines you face.
✅ Do This: If you feel harsh shifts or see the wrench light, book an inspection. Ask the technician to diagnose against TSB 25-2126 (2017–2020) or 24-2254 (2021–2022 built on or before 15 August 2022). Ask them to record the stored codes on the repair order.
FAQ
1. Is there a Ford 10-speed transmission settlement?
No. As of September 28, 2026, O’Connor v. Ford has no settlement, and class certification was denied in September 2026.
2. Do I need to sign up for the Ford 10-speed lawsuit?
No. Without a certified class, there is nothing to sign up for and no claim form exists.
3. Is my 2021 F-150 in the 10-speed lawsuit?
No. The case covered 2017–2020 10R80 F-150s only. Some 2021 trucks fall under park-system recall 26S48 instead.
4. Which states did the Ford 10-speed lawsuit cover?
Plaintiffs proposed classes in Illinois, California, Massachusetts and New York for 2017–2020 10R80 F-150s. None were certified.
5. What is the CDF drum problem on the 10-speed?
Ford’s bulletin 25-2126 links harsh or delayed shifts on 2017–2020 F-150s to the CDF clutch cylinder sleeve moving and leaking fluid.
6. Will Ford fix 10-speed harsh shifting for free?
Only within warranty. Bulletin repairs follow normal coverage, and standard powertrain coverage runs 60 months or 60,000 miles.
7. Is the 1.4 million F-150 transmission recall for the 10-speed?
No. Recall 26V237 covers 2015–2017 F-150s with the six-speed 6R80, not the 10R80 ten-speed.
8. Is my 10-speed F-150 safe to drive with harsh shifts?
Harsh engagement and Park faults are safety concerns under Ford’s own bulletin and recalls. Have it inspected by a qualified technician before relying on it.
9. Should I wait for the lawsuit before repairing my F-150 10-speed?
No. With class certification denied, there is no class reimbursement to wait for. Keep every repair order.
10. Can I use lemon law instead of the 10-speed lawsuit?
Possibly, but your state’s repair-attempt limits and time windows decide it. An attorney licensed in your state can confirm.
The bottom line
The Ford 10-speed lawsuit no longer offers F-150 owners a group remedy. Three steps still help:
- Run your VIN for 18S09, 26S48 and 25SB3.
- Get harsh shifts diagnosed against the right bulletin.
- Keep every repair record.
We’ll update this page when the docket moves or a recall remedy launches.
