P2708 on 2020-2023 Lincoln Aviator — Shift Solenoid "F" Stuck On
1 vehicles · 1 makes
Most Reported On
P2708 is an OBD-II diagnostic trouble code meaning “Shift Solenoid "F" Stuck On.” A generic (SAE-defined) powertrain code that applies to most OBD-II vehicles with an automatic transmission, and is reported across Chrysler, Ford, Dodge, Ram, Hyundai/Kia, Toyota/Lexus, Mazda, Honda and VW. The transmission control module commanded shift solenoid "F" off, but hydraulic pressure or gear-ratio feedback indicates the solenoid is still applied — stuck in the ON position. Because shift solenoids route the fluid pressure that applies each clutch pack, a stuck solenoid usually shows up as harsh or delayed shifts, slipping, being locked in one gear, or stalling when coming to a stop. Severity typically starts moderate and worsens quickly, so it should not be ignored. This code is most commonly reported on 2020-2023 Lincoln Aviator.
Common Causes

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.
