P07F7 on 2020-2023 Lincoln Aviator — Gear 10 Incorrect Ratio
1 vehicles · 1 makes
Most Reported On
P07F7 is an OBD-II diagnostic trouble code meaning “Gear 10 Incorrect Ratio.” Generic (SAE-defined) powertrain code for vehicles with 10-speed automatic transmissions, most commonly the Ford 10R60/10R80 and GM 10L80 family. It is part of a series where P07F6 is Gear 9 and P07F7 is Gear 10. The transmission control module compares input shaft speed to output shaft speed and found that the actual ratio in 10th gear did not match the ratio it commanded. In practice the driver may feel harsh or delayed engagement, harsh or delayed shifts, flare on the shift into top gear, or the transmission may refuse to reach 10th at all. Because slipping clutches generate heat and debris, this should be diagnosed rather than cleared and ignored. This code is most commonly reported on 2020-2023 Lincoln Aviator.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
