Ford F-150 Transmission Problems by Year 2015-2024
NHTSA complaints, recalls and Ford bulletins for every model year
Which F-150 years draw the most transmission complaints, which recalls apply to your truck, and what Ford's own service bulletins say the fix is. Every figure below comes from NHTSA records and Ford documents, last checked September 18, 2026.
F-150 Transmission Problems by Model Year: Complaints, Recalls and Bulletins
The 2018 F-150 has the most power train complaints on file with NHTSA: 744 of its 1,899 total owner complaints. The 2019 is next with 508, then the 2021 with 435. These are owner reports, not confirmed failures, and newer trucks have had less time to collect them.
The 2019 F-150 has no power train recall at all, as of September 18, 2026. For 2017-2020 trucks with the 10-speed, Ford has answered harsh and delayed shifting with service bulletins. A bulletin is a repair instruction for dealers, not a recall, so the work is normally covered only while the truck is under warranty. The latest, bulletin 25-2126 from March 2025, has technicians test for an internal hydraulic leak and, if the test calls for it, replace the CDF clutch cylinder.
2015 and 2016 trucks use the 6R80 6-speed. The 10R80 10-speed arrived on some 2017 trucks. For 2018, Ford bulletin 18-2274 lists the 10R80 behind the 2.7L, 3.5L and 5.0L engines, while NHTSA recall 17V-669 shows the 3.3L V6 kept a 6-speed.
| Model year | Power train complaints (NHTSA) | Transmission and driveline recalls | What to check first |
|---|---|---|---|
| 2015 | 198 of 1,425 | 26V-237 (unexpected downshift into second gear) | Run the VIN for recall 26V-237. If the truck slips or flares between gears, have the fluid checked and the codes read before it gets worse. |
| 2016 | 376 of 1,749 | 26V-237 | Same recall as the 2015. Nearly twice the power train complaints of the 2015, so take a sudden hard downshift seriously. |
| 2017 | 319 of 1,120 | 17V-053, 17V-671, 18V-213, 26V-237 | Find out whether yours is the 6-speed or the 10-speed, then run the VIN. 17V-671 and 18V-213 apply to 10-speed trucks only. |
| 2018 | 744 of 1,899 | 18V-213, 18V-214, 17V-669, 26V-375 | Check the build date on the door jamb. Built on or before May 15, 2018: ask whether the bulletin 18-2274 reprogram was done. Still shifting hard: bulletin 25-2126 leak test. |
| 2019 | 508 of 998 | None | No recall to wait for. Ask for the bulletin 22-2428 and 25-2126 checks: software first, then the hydraulic leak test. |
| 2020 | 234 of 544 | 20V-197 (shift cable lock clip) | Run the VIN for 20V-197. Harsh or delayed shifts fall under bulletin 25-2126. |
| 2021 | 435 of 1,260 | Transmission: 22V-188, 25V-169, 26V-402. Driveline: 21V-381, 21V-986, 22V-623, 23V-896 | Seven power train recalls, the most of any year here. Run the VIN first. Harsh or delayed engagement is covered by bulletin 24-2254. |
| 2022 | 230 of 800 | Transmission: 23V-070. Driveline: 21V-986, 22V-623, 23V-896 | Run the VIN for 23V-070 (a loose bolt can stop Park from engaging). Built on or before August 15, 2022: bulletin 24-2254 applies. |
| 2023 | 190 of 502 | Transmission: 23V-070. Driveline: 23V-128, 23V-896, 25V-512 | Run the VIN for 23V-070. Trucks with the Trailer Tow Max Duty package should also check 23V-896 and 25V-512 (rear axle hub bolt). |
| 2024 | 64 of 221 | Transmission: 25V-164. Driveline: 25V-512 | Run the VIN for 25V-164: the valve body may have been machined incorrectly, which can cause reverse gear failure. |
Complaint counts are owner complaints filed with NHTSA whose component includes power train, pulled September 18, 2026, summed across F-150 cab styles and de-duplicated by complaint number. They are reports, not confirmed failures, and they cover the whole power train, not only the transmission. Recall numbers are NHTSA campaign numbers. A recall applies to certain trucks in a model year, so your VIN decides whether yours is covered.

What to do next, based on what your truck is doing
- Harsh, delayed or clunky shifts on a 2017-2022 truck. Software is the first step in Ford's bulletins, but a leaking clutch cylinder sleeve is not fixed by software. A diagnostic visit sorts out which one you have before money goes into parts. Transmission diagnostics
- A recall number in the table matches your year. Recall repairs are free at a Ford dealer, not at an independent shop. Run your VIN at nhtsa.gov and book it with the dealer. For everything a recall does not cover, see Ford repair in Rohnert Park
- Slipping, flare between gears or burnt-smelling fluid. Those point to clutch wear rather than software. Stop towing and have it looked at before the damage spreads. Transmission rebuild
- You tow, idle for long stretches or drive dusty roads. Ford moves the fluid change from 150,000 miles to every 30,000 miles under those conditions. Transmission service

Common Ford F-150 Transmission Problems
Based on our 45+ years of experience, these are the most common transmission issues we see with this vehicle model.
2017-2020 10-Speed Harsh or Delayed Shifting (10R80)
Harsh, bumpy or delayed shifting is the complaint we hear most on F-150s with the 10R80 10-speed. There is no recall for it. Ford has handled it through service bulletins. Bulletin 18-2274 (September 2018) has dealers reprogram the powertrain control module on 2018 trucks built on or before May 15, 2018. Bulletin 25-2126 (March 2025) covers 2017-2020 trucks: the technician tests for a hydraulic leak inside the transmission and, if the test calls for it, replaces the CDF clutch cylinder and the clutch and planetary container cylinder. Ford's stated cause is a sleeve in that clutch cylinder moving out of place. Software is the first step, but a sleeve that has moved is a parts repair that no reprogram will fix.
Common Symptoms
- •Hard shifts between gears (especially 3rd to 5th)
- •Jerking or lurching during normal acceleration
- •Delayed engagement when shifting from Park (2-3 second delay)
- •Clunking or grinding noise during gear changes
- •Issue more pronounced when transmission is cold
2021-2022 10-Speed Harsh or Delayed Engagement (Bulletin 24-2254)
Ford bulletin 24-2254 (August 2024) covers 2021-2022 F-150s with the 10R80, hybrids excluded, built on or before August 15, 2022. Ford names the cause: the sleeve in the CDF clutch cylinder moves, which opens hydraulic leaks inside the transmission. That is a parts repair, not a software update. The 2021 model year also carries seven power train recalls, three of them on the transmission itself, so run the VIN first.
Common Symptoms
- •Harsh or delayed engagement into Drive or Reverse
- •Harsh or delayed shifts on the road
- •Check engine light with transmission codes
- •Sometimes only while the transmission is still cold
2015-2017 6R80 Transmission Slipping (Clutch Pack Failure)
2015-2017 F-150s with the 6R80 6-speed can slip when clutch packs wear or the solenoid pack fails. Slipping that is caught early is often a smaller job than slipping that has been driven on for months, so have it diagnosed before it spreads. Separate from slipping: NHTSA recall 26V-237 (April 2026) covers certain 2015-2017 F-150s because a lost signal between the transmission range sensor and the powertrain control module can make the truck downshift into second gear without warning. That recall repair is free at a Ford dealer.
Common Symptoms
- •RPMs increase without acceleration (especially 2nd to 3rd gear)
- •Transmission slips between gears
- •Check engine light with P0751 code
- •Burning smell from transmission fluid
- •Problem worsens over time if left untreated
Immediate attention required! This issue can lead to complete transmission failure if not addressed.
Torque Converter Shudder
Torque converter shudder is often caused by degraded transmission fluid or a failing torque converter clutch. Early intervention with a fluid flush can sometimes resolve the issue.
Common Symptoms
- •Vibration at 35-45 mph
- •Feels like driving over rumble strips
- •Worse when transmission is warm
- •Improves temporarily after fluid change
Transmission Fluid Leak at Lead Frame
The lead frame connector seal is prone to failure, causing fluid leaks. This is a known issue with a relatively straightforward repair involving seal replacement.
Common Symptoms
- •Transmission fluid puddle under vehicle
- •Low fluid warnings on dashboard
- •Shifting problems due to low fluid
- •Visible leak at transmission pan area
Delayed Reverse Engagement (10-Speed)
A pause before Reverse takes hold on a 10-speed F-150 has more than one possible cause. Ford bulletin 22-2428 (May 2023) lists four for harsh or delayed engagement: control module software, the solenoid identification strategy, sticking valves in the main control valve body, and movement of the CDF clutch cylinder sleeve. Which one you have decides whether the fix is a reprogram or parts, so it takes testing, not guessing. On a 2024 truck, check recall 25V-164 first: the valve body may have been machined incorrectly, which can cause reverse gear failure.
Common Symptoms
- •2-5 second delay when shifting to Reverse
- •Clunk or thud when Reverse finally engages
- •Normal forward gear operation
- •Issue more pronounced when cold
Transmission Overheating
Common when towing heavy loads without proper cooling. May require auxiliary transmission cooler installation or thermostat replacement.
Common Symptoms
- •Transmission Temperature warning light
- •Reduced power/limp mode activation
- •Burnt transmission fluid smell
- •Dark or discolored fluid
10-Speed Adaptive Shift Learning (After a Reprogram)
The 10-speed adapts its shifts to the truck and the driver. After a reprogram it has to relearn. Ford's own customer note in bulletin 18-2274 says to expect firmer than normal upshifts and downshifts for several days afterward. If the shifts are still rough after a couple of weeks of normal driving, relearning is not the cause and the truck needs the bulletin checks described above.
Common Symptoms
- •Inconsistent shift quality: good one day, rough the next
- •Transmission "hunts" for correct gear
- •Rough shifts after battery disconnect
- •Improves over the following days of normal driving
Valve Body Failure
Complete valve body failure requires replacement of the entire valve body assembly. This is a complex repair requiring specialized tools and expertise.
Common Symptoms
- •Multiple gear shift issues
- •Transmission stuck in one gear
- •No movement in Drive or Reverse
- •Multiple transmission codes present
Immediate attention required! This issue can lead to complete transmission failure if not addressed.

Technical Service Bulletins (TSBs)
What are TSBs? Technical Service Bulletins are manufacturer advisories about known issues and recommended repair procedures. They are not recalls but provide valuable repair guidance.
10R80 Harsh or Bumpy Shift and Engagement - 2018 Trucks Built On or Before May 15, 2018
TSB #18-2274 • Issued: 2018-09-07
Covers 2018 F-150s with the 2.7L, 3.5L or 5.0L engine and the 10R80. Ford's fix is to reprogram the powertrain control module. The bulletin warns owners that upshifts and downshifts may feel firmer than normal for several days afterward while the transmission relearns.
Related Symptoms:
10R80 Harsh or Delayed Shifts and Engagements - 2017-2023 Trucks Built On or Before August 15, 2022
TSB #22-2428 • Issued: 2023-05-26
Ford's umbrella bulletin for 10-speed shift complaints. It replaced four earlier bulletins (22-2139, 22-2102, 21-2377 and 21-2434). It names four possible causes: powertrain or transmission control module software, the solenoid identification strategy, sticking valves in the main control valve body, and movement of the CDF clutch cylinder sleeve. The repair depends on which one the checks point to.
Related Symptoms:
10R80 Harsh or Delayed Engagement and Shifts - 2021-2022 Trucks, Hybrids Excluded
TSB #24-2254 • Issued: 2024-08-23
For 2021-2022 F-150s with the 10R80 built on or before August 15, 2022. Ford ties the symptoms, which can include a check engine light with shift solenoid performance codes such as P0751, to the CDF clutch cylinder sleeve moving and leaking hydraulic pressure. This is a parts repair, not a software update. Ford lists it as eligible under the New Vehicle Limited Warranty.
Related Symptoms:
10R80 Harsh or Delayed Shifts - 2017-2020 Trucks, CDF Clutch Cylinder Replacement
TSB #25-2126 • Issued: 2025-03-31
Replaced bulletin 25-2018. For 2017-2020 F-150s, the technician checks the hydraulic circuit for leakage and, if the test calls for it, replaces the CDF clutch cylinder and the clutch and planetary container cylinder. One branch of the diagnosis asks whether the symptoms show up only while the transmission fluid is still cold. A bulletin is not a recall, so outside of warranty the repair is normally paid for by the owner.

View Guide →Frequently Asked Questions
Is there a recall on the 2019 F-150 transmission?
No. As of September 18, 2026, NHTSA lists nine recalls on the 2019 F-150 and none of them is filed under power train. The 2019 still drew 508 power train complaints, the second-highest count of any 2015-2024 F-150. Ford has handled the 10-speed shift complaints through technical service bulletins, which are repair instructions for dealers, not free recall repairs. Check your own VIN at nhtsa.gov/recalls, because new campaigns are added over time.
Which F-150 years have the most transmission complaints?
By NHTSA power train complaint count, 2018 is the highest with 744, followed by 2019 with 508, 2021 with 435 and 2016 with 376. The 2024 has the fewest so far with 64, but it is also the newest truck on the list. Complaint counts are owner reports, not confirmed defects, and they are not adjusted for how many trucks Ford sold each year.
Is there a class action over the F-150 10-speed transmission?
Yes, one is on file. O'Connor v. Ford Motor Company was filed in federal court in Illinois in 2019 over the 10R80 in 2017-2020 F-150s. A September 2026 memorandum opinion denied class certification, which means the case was not approved to go forward on behalf of all owners. Ford denies that the transmission is defective. We are a repair shop, not lawyers, so talk to an attorney about your own rights.
Is the 10-speed transmission reliable in newer F-150s?
It depends on the year. The 2018 and 2019 trucks drew the most power train complaints to NHTSA, and Ford has issued several bulletins for harsh or delayed 10R80 shifts on trucks built on or before August 15, 2022. Ford's bulletins put the cause down to software, sticking valves in the valve body, or a clutch cylinder sleeve that moves and leaks pressure. Complaint counts drop for 2022 through 2024, though those trucks have also had less time on the road.
How often should I change the transmission fluid in my F-150?
Ford's owner's manual lists a transmission fluid and filter change at 150,000 miles on the normal schedule. Under Special Operating Conditions, which include towing, extensive idling, heavy commercial use and dusty roads, Ford's interval is every 30,000 miles. Our shop advice is to have the fluid condition looked at around 30,000 and 60,000 miles even if you drive on the normal schedule, because it is the cheapest early warning you can get.
What are signs my F-150 transmission is failing?
Warning signs include slipping gears, delayed engagement, rough shifting, transmission fluid leaks, burning smell, warning lights, and unusual noises. If you experience any of these symptoms, have your transmission inspected immediately to prevent costly damage.
Can I tow with my F-150 if it has transmission problems?
We strongly advise against towing if you are experiencing any transmission issues. Towing puts additional stress on the transmission and can turn a minor problem into a major failure. Have the transmission repaired before resuming towing activities.
Does my F-150 take MERCON LV or MERCON ULV?
It depends on the transmission. The 10R80 10-speed takes MERCON ULV only. Ford's 2020 owner's manual names Motorcraft XT-12-QULV, specification WSS-M2C949-A. The 6-speed trucks take MERCON LV. The two fluids are not interchangeable, and the wrong one can cause shift problems and wear. If you are not sure which transmission you have, call (707) 584-7727 with your VIN before anyone drains the pan.
How much does it cost to rebuild an F-150 transmission?
The cost of a complete transmission rebuild for an F-150 varies based on the extent of damage, whether it is a 6-speed or 10-speed model, and specific parts needed. We provide professional diagnostics and detailed estimates before any work begins. All rebuilds include our comprehensive 2-year/24,000-mile warranty. Call (707) 584-7727 for a personalized quote based on your vehicle's specific needs.
My 2018 F-150 has harsh shifts. What should I do first?
Start with the build date on the driver's door jamb sticker. If your 2018 was built on or before May 15, 2018, Ford bulletin 18-2274 calls for a powertrain control module reprogram, and shifts can feel firmer for several days afterward while the transmission relearns. If the truck has already had that update and still shifts hard, the next step is bulletin 25-2126: a hydraulic leak test and, if it fails, replacement of the CDF clutch cylinder. Check your VIN for open recalls too, since the 2018 has four power train campaigns. Call (707) 584-7727 to book a diagnosis.
What does delayed reverse engagement mean in my F-150?
On a 10-speed built on or before August 15, 2022, Ford bulletin 22-2428 lists four possible causes for delayed engagement: control module software, the solenoid identification strategy, sticking valves in the main control valve body, and a clutch cylinder sleeve that has moved. Only the first is a software fix. On a 2024 truck, check recall 25V-164 first. It covers a valve body that may have been machined incorrectly and can cause reverse gear failure, and a Ford dealer repairs it free.
My 2015 F-150 is slipping between 2nd and 3rd. Is it fixable?
Usually, yes. The 2015-2017 trucks with the 6R80 6-speed can slip from worn clutch packs or a failing solenoid pack, and a scan plus a road test tells the two apart. Continuing to drive on a slipping transmission makes the damage worse. Also run your VIN for recall 26V-237, filed in April 2026 for 2015-2017 F-150s. It covers an unexpected downshift into second gear caused by a lost sensor signal, and the fix is free at a Ford dealer. Call (707) 584-7727 to schedule a diagnostic scan.
Can I prevent F-150 transmission problems with maintenance?
Maintenance helps, but it will not fix a software fault or a moved clutch cylinder sleeve. Follow Ford's schedule: fluid and filter at 150,000 miles for normal driving, or every 30,000 miles if you tow, idle for long periods or drive dusty roads. Use MERCON ULV in the 10-speed and MERCON LV in the 6-speed. Stay inside the tow rating on your door jamb sticker. Get any transmission code scanned promptly, and check your VIN for recalls once or twice a year. Call (707) 584-7727 to schedule service.
