P2708 on Lincoln: How to Diagnose & Fix
Shift Solenoid "F" Stuck On
1 Lincoln model · 1 documented issue
P2708 on Lincoln by model: symptoms, diagnosis and fix
Some 2020-2023 Lincoln Aviators equipped with a 10R60 and built on or before December 23, 2022, or a 10R80 MHT and built on or before August 15, 2022, may have harsh or delayed engagement and/or harsh or delayed shifts. Ford TSB 22-2428 says the condition may involve PCM/TCM software, the transmission solenoid-ID strategy, sticking main-control valves, or axial movement of the CDF clutch-cylinder sleeve. The complaint may occur with or without a malfunction indicator and the bulletin's listed transmission DTCs. The symptom alone does not select a valve body, CDF cylinder, or complete transmission.
Common Symptoms
- Harsh engagement
- Delayed engagement
- Harsh shift
- Delayed shift
- Malfunction indicator with a bulletin-listed transmission DTC
How to Fix
Have a Ford/Lincoln-capable technician confirm the transmission and build date, retrieve PCM/TCM faults, and follow TSB 22-2428 in order. The bulletin begins with available PCM/TCM programming and an adaptive-learning drive cycle, then uses the stored faults and clutch behavior to select an accelerated main-control break-in routine. If the condition remains, the procedure can require main-control overhaul and, only after the bulletin's later tests fail, condition-specific internal transmission repair. Parts and coverage must be selected by VIN and the actual failed step; this record intentionally has no buy link.
Owner tips & cautions
- TipRecord the exact shift or engagement event and ask for the PCM/TCM fault report plus the TSB decision-tree step that failed before approving internal transmission work.
- WarningDo not order a valve body or CDF part from harsh shifting alone; Ford's procedure can resolve the condition through programming, adaptive learning, or clutch cycling before parts are selected.

Frequently asked questions
What does P2708 mean on a Lincoln?
P2708 stands for "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. On Lincoln it is documented across 1 model: Aviator.
What are the most common causes of P2708?
The most common causes of P2708 are: Failed or electrically stuck (shorted/open) shift solenoid F, Debris or varnish holding the solenoid valve open in the valve body, Contaminated, burnt, or low transmission fluid, Damaged wiring, chafed harness, or corroded connector at the transmission case connector, Faulty or leaking valve body, Failed transmission control module (rare — check wiring and fluid first). The specific cause varies by vehicle.
How much does it cost to fix P2708 on a Lincoln?
Repair costs vary widely with the root cause and Lincoln model; each issue on this page carries its own estimate where one is published.
