P08DFShift Solenoid L Performance/Stuck Off

  • 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
Functional fault of shift solenoid L: the TCM switches the valve on, but speed sensor data show that the intended clutch did not take up, so the valve acts as if stuck off. No manufacturer documents this code publicly. The detection logic is known from the analogue for solenoid A: Ford compares the obtained gear or shift pattern over three solenoid events, and GM's P0751 counts repeated slip of at least 400 rpm in a ratio window that does not match first gear, with the MIL after two trips. Typical causes are a valve jammed by debris, low line pressure or a leaking clutch circuit rather than wiring. CARB requires the check. P08E0 is the stuck-on fault. Expect flare or a missing gear.
What you may notice
  • Check engine or transmission warning light on
  • Engine flare between gears
  • Gear missing or skipped
Likely causes
  • LikelyShift spool jammed by debris
  • PossibleLow line pressure or low fluid level
  • PossibleLeak in the clutch circuit fed by the valve
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
