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 owners wrote

“My transmission started down shifting on its own while driving one morning and the check engine light and wrench light illuminated. I took it to the dealership that afternoon and had the conductor board replaced. They said it was the speed sensor that malfunctioned.”

Filed Feb 18, 2026

“I was driving down the highway and the transmission started shifting erratically and went to 3rd almost causing me to wreck. Check engine light and wrench icon came on and had to pull over immediately. Code says faulty transmission range sensor and lead frame are the cause.”

Filed Sep 16, 2025

“Transmission abruptly downshifts without warning. Cluster displays wrench icon and see manual but does not store a code in OBDII. Truck runs in “limp mode” restarting seems to clear the issue. Ford states no code no problem. I have video of issue happening.”

Filed Aug 2, 2025

“Truck suddenly downshift into 5th gear and bucked for second starting out to get up to 60 mph Wrench light comes on transmission at 60 mph. holding back due to communications from the output sensor and the PCM. Took it to a ford dealer and had transmission flushed it was diagnosed with code PO722. Dealer said earlier years of these type of transmission on F150 had same problems.”

Should you keep driving it?

This page can't tell you that. 0 of 94 reports involved a crash. 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.
