P08DD code meaning
Shift Solenoid K Control Circuit/Open
Powertrain system Generic code P08xx codes Check engine light
What P08DD means
Signals that the control circuit of shift solenoid K is open, so commanding the valve produces no current: a broken wire, a pushed-out terminal, a burnt coil or a failed internal transmission harness. No manufacturer documents this code publicly. Ford handles opens through the base code of each solenoid, P0750 for solenoid A, while GM's tables fold them into the circuit-high code P0974, so a separate open code like this one stays unused in both systems. CARB requires transmission outputs to be checked for opens. P08DB and P08DC are the short-circuit codes, P08D8 the general electrical fault. Without power the valve stays in its rest position, so one gear range drops out.
P08DD at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P08DD
- Check engine or transmission warning light on
- Some gears no longer available
- Limp mode with fixed gear
Common causes of P08DD
- Most likelyBroken wire or pushed-out terminal
- PossibleFailed internal transmission harness
- PossibleBurnt-out solenoid coil
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P08DD means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8 | Area: transmission. |
| DD | The exact fault in that area. |
What to do next
- Note P08DD and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P08DD
What does P08DD mean?
P08DD means "Shift Solenoid K Control Circuit/Open". Signals that the control circuit of shift solenoid K is open, so commanding the valve produces no current: a broken wire, a pushed-out terminal, a burnt coil or a failed internal transmission harness. It is a generic code, so it means the same on every make.
Is it safe to drive with P08DD?
Drive gently and only to a workshop. With P08DD the car can go into limp mode (reduced power) to protect itself.
Will P08DD fail an emissions test?
Yes, it can. P08DD is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P08DD to fix?
Difficulty: hard. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P08DD clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
