Ever noticed your F150 jerking when you shift gears or heard a concerning clunk from underneath your truck? You might be experiencing one of the many transmission problems that have plagued Ford’s flagship pickup. These issues aren’t just annoying—they can be dangerous and expensive to fix.
Most Common Ford F150 Transmission Problems
Ford F150 trucks have faced persistent transmission issues across multiple model years, with problems varying between the 6-speed (6R80) and 10-speed (10R80) transmissions.
6-Speed Transmission Issues (2011-2017 Models)
The 6-speed automatic transmission found in older F150 models comes with some serious concerns:
- Sudden downshifting to first gear at highway speeds, creating dangerous driving situations
- Loss of vehicle control during these unexpected downshifts
- Rear wheels locking up or skidding when the transmission malfunctions
- Rapid deceleration without driver input
These problems stem from a loss of signal between the transmission output shaft speed sensor and the powertrain control module. According to NHTSA documentation, this communication failure can be caused by contamination, electrical shorts, connector corrosion, or sensor failures.
One Ohio owner of a 2016 F150 reported that “the truck automatically shifted from 6th Gear to first gear nearly throwing me through the windshield” while traveling at 70 mph on the highway.
10-Speed Transmission Problems (2017-Present Models)
Ford introduced the 10-speed automatic transmission in 2017 F150 trucks, hoping to provide more power and fuel efficiency. Unfortunately, it brought its own set of issues:
- Harsh shifting, especially when the engine is cold
- Clunking or banging noises when starting the engine
- Hesitation or delays between gear changes
- Transmission slipping out of gear unexpectedly
- Vehicle jerking or lunging during normal driving
- Wrench warning light illumination on the dashboard
- Complete loss of power while driving
A 2023 F150 owner described experiencing “frequent harsh shifts” in “probably 3/4 the cases of decelerating to a stop,” describing it as “a slight bump (and sometimes it’s more like a shove) on every gear from 6th on down.”
The 10-speed transmission problems may be related to manufacturing defects, including:
- False detection of low transmission fluid pressure
- Malfunctioning solenoid strategy
- Stuck valves within the transmission
- Failures of axial components, particularly the CDF drum
Recent Recalls and Investigations
Ford has issued multiple recalls for F150 transmission problems, showing just how widespread these issues are.
The June 2024 Recall
In June 2024, Ford recalled approximately 552,000-668,000 F150 pickup trucks in the United States from the 2014 model year. The problem? A serious transmission defect causing unexpected downshifting into first gear regardless of vehicle speed.
Ford’s documentation revealed:
- 300 warranty reports related to this issue
- 96 field reports from dealers
- 124 customer complaints
- 40 trucks reporting rear wheel lock-up or loss of control
- 2 injury reports and 1 crash potentially linked to this defect
The fix involves dealers updating the powertrain control software to illuminate the check engine light if communication is lost between the PCM and speed sensor.
March 2025 NHTSA Investigation
More recently, in March 2025, the National Highway Traffic Safety Administration launched an investigation into nearly 1.3 million Ford F150 pickup trucks from the 2015-2017 model years equipped with 6-speed transmissions.
This investigation was prompted by 138 complaints from consumers about unexpected transmission downshifts at highway speeds, causing rapid deceleration and potentially dangerous driving conditions.
History of Previous Recalls
These recent actions follow a pattern of F150 transmission issues dating back several years:
- In 2016, Ford recalled 153,000 F150 vehicles with six-speed automatic transmissions from 2011-2012 model years
- In 2019, Ford expanded that recall to include 1.48 million F150 trucks, adding 2013 models
- Later in 2019, Ford issued another recall for 107,000 2013 F150 vehicles due to issues with the initial fix
