Transmission warning light on other F-150 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2020, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
This sheet is for a "Service Transmission" message, a transmission fault warning or a wrench light. Owners say it often shows up with lost power, a stall or a car that won't accelerate, and sometimes clears on the next start.
What got replaced
Owners who name the part that was replaced mention the transmission control module (8 reports).
Recalls and investigations
2 recalls on the transmission and drivetrain cover the 2014 model year. A recall on the same system isn't always the same failure, so read the defect text.
A loss of signal between the transmission output shaft speed sensor and the powertrain control module (PCM) can cause the transmission to unexpectedly downshift into first gear.
A loss of signal between the transmission output shaft speed sensor and the powertrain control module can cause the transmission to unexpectedly downshift into first gear, regardless of vehicle speed.

Should you keep driving it?
This page can't tell you that. 1 of 58 reports involved a crash and 2 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
