Recall 26V378 affects 44,963 2014 Ford F-150 trucks for an unexpected first-gear downshift. Repair will be free at any franchised Ford dealer once available.
Ford is recalling 44,963 2014 F-150 trucks because an incorrect earlier recall repair can leave the transmission output shaft speed sensor signal lost between the sensor and the powertrain control module. The signal loss can make the transmission unexpectedly downshift into first gear, resulting in loss of vehicle control, and the Ford dealer repair will be free once available.

What's wrong?
The output shaft speed sensor on the 2014 Ford F-150 reads how fast the transmission output shaft is turning. The powertrain control module, the truck's main engine and transmission computer, uses that signal to choose the right gear and keep shifting predictable.
On affected trucks, the signal between the sensor and the computer can drop out. Ford identified several causes in this group, including contamination, a power short to ground, connector corrosion, damaged connector pins, and incorrect sensor output. If the computer loses the speed signal, the transmission can unexpectedly downshift into first gear instead of staying in the gear that matches road speed.
Owners can notice a Malfunction Indicator Light after the downshift. The truck can return to normal operation if the signal recovers while driving, or it can need to be stopped and restarted before the transmission works normally again.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific pickup truck is included.
What's the safety risk?
An unexpected downshift into first gear can cause loss of vehicle control and increases crash risk. If the Malfunction Indicator Light comes on or the transmission stops shifting normally, slow down, pull over when safe, and call a Ford dealer for guidance. Repair will be free at any franchised Ford dealer once available.
What should I do?
- Check your VIN on or after July 6, 2026 to confirm your 2014 Ford F-150 is included in this recall.
- Watch for Ford's owner letter, which is expected to be mailed July 6, 2026.
- Contact a franchised Ford dealer once the repair opens to schedule the free PCM software update that addresses the signal loss tied to an unexpected first-gear downshift.
- Reference recall number 26V378 and Ford recall 26S45 when you call.
- Drive cautiously until the repair is complete. Leave extra following distance and be ready for an unexpected downshift.
What happens at the repair
Once the final dealer repair is available, a Ford technician will update the PCM software. The repair is a software update, not a transmission hardware replacement, and parts and labor are covered under the recall. Ford uses its standard reimbursement plan for owners who already paid out of pocket for a related repair before the recall notice. Keep the repair paperwork and ask Ford customer service or the dealer service desk how to submit documentation under that plan.
