P0767 Code: Shift Solenoid D Stuck On
🟠 Moderate severity · drivable
Drivable, but shifting may be harsh or erratic and continued driving can damage the transmission. Fix it soon.
What P0767 means
The shift solenoid D is stuck in the on position, so its fluid circuit stays open when it shouldn't. That can make the transmission hold the wrong gear, shift harshly, or fail to release a circuit — the opposite failure mode from a stuck-off solenoid.
Symptoms
- Check engine light on
- Harsh or erratic shifting
- Transmission may be stuck in one gear
- Possible limp mode
Common causes
- most common: Stuck shift solenoid D (debris or wear)
- common: Dirty or contaminated transmission fluid
- less common: Valve body bore wear
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Change the transmission fluid and filter | Yes | $100–250 |
| Replace the shift solenoid D | Mechanic | $200–500 |
Frequently asked questions
What does 'stuck on' mean?
The solenoid is held in its open/on position, so its fluid circuit cannot close. This usually causes harsh or incorrect shifting.
Is a stuck-on solenoid worse than stuck-off?
Both are serious. Stuck-on often causes harsh, abrupt shifts, while stuck-off prevents a shift from happening at all.
How much does it cost to fix?
$100–250 for a fluid change, or $200–500 for a new solenoid.
