P08D6Shift Solenoid K 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
- Indicates that shift solenoid K was commanded on but the gear or clutch behind it never engaged, as if the valve stayed in its off position. No manufacturer documents this code publicly. A documented model is GM's P0751 for solenoid A on the 6-speed units: with first gear commanded, the TCM counts a fault when slip reaches 400 rpm and the measured ratio sits in a fixed window that points to the wrong gear, and it needs two trips to light the MIL. Ford infers a solenoid failed off from the obtained gear or shift pattern over three solenoid events. CARB requires this functional check. The reverse fault is P08D7. Typical signs are engine flare during shifts and a skipped gear.
