P2708Shift Solenoid F Stuck On

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
  • Needs a drive cycle to confirm a fix
How the car detects it
P2708 means the clutch fed by shift solenoid F stays applied when the controller expects it released, although the wiring checks pass. Ford's 2024 OBD summary maps it to P2706 with the failed-on byte 7E for its 10R60/10R80, 8F35/8F40, 8F57 and 8F24 units. One bad event lasts roughly 2.5 s outside a shift or 1 s during one; each adds 3 to a counter, each correct reading removes 1, and 9 stores the code. Since a ratio test cannot separate valve and clutch, Ford's 10R80 bulletins (21-2315 up to 26-2395) treat it as a hydraulic fault, e.g. a shifting sleeve on the CDF clutch cylinder that leaks oil. Audi bulletin 2078831 lists P270800 with a gear actuator fault on 2025 A5/Q5 dual-clutch boxes. Expect harsh or late shifts and a lit MIL. P2707 is the opposite case.
What you may notice
  • Harsh or delayed engagement and shifts
  • MIL lit, often with other stuck-on or gear-ratio codes
  • Binding or shudder as two clutches work against each other
  • Transmission may hold a fixed gear for protection
Likely causes
  • LikelyInternal oil leak at a clutch cylinder or sleeve keeping the clutch applied (Ford 10R80 CDF cylinder)
  • PossibleShift solenoid F mechanically sticking in the applied position (dirt, wear)
  • PossibleOutdated PCM/TCM calibration; Ford bulletins combine reprogramming with the repair
  • RareDebris or degraded fluid jamming valves in the valve body
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
