P2707 Shift Solenoid F Performance/Stuck Off

P2707 is not an electrical fault: the circuit to shift solenoid F is intact, but the clutch it controls does not apply when commanded, as if the solenoid stayed off. Ford stresses that a ratio-based check cannot tell a solenoid failure apart from other faults in the clutch hydraulics. In its 2024 summary P2707 equals P2706 with the functionally-failed-off byte for the 10R and 8F families. The test runs whenever the solenoid is switched from off to on; a bad event lasts about 2.5 s when not shifting or 1 s within a shift, adds 3 to a fault counter, a correct state takes 1 off, and the code sets at 9. Bulletins name a damaged F clutch piston on the 8F57 (SSM 50617) and a delaminated fluid pump gasket causing several stuck-off codes on 2021 Super Duty 10R140 units (SSM 50512). P2708 is the stuck-on case.

Likely causes

Leaking or damaged clutch F piston or seals
Shift solenoid F or its valve sticking in the off position
Insufficient supply pressure, e.g. damaged fluid pump gasket
Low transmission fluid level

Symptoms

  • Gears using clutch F missing or slipping
  • Return to Park or no engagement in drive or reverse
  • Check engine light on
