P0756 Code: Shift Solenoid B Performance or Stuck Off
🟠 Moderate severity · drivable
Drivable, but shifting may be harsh or erratic and continued driving can damage the transmission. Fix it soon.
What P0756 means
The shift solenoid B is stuck in the off position, so its fluid circuit won't open when commanded. That means the shift (or pressure change) this solenoid controls can't happen — the transmission may be unable to reach a particular gear, or pressure stays too low. This is a mechanical/hydraulic sticking fault, not a wiring issue.
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 B (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 (may free a lightly-stuck solenoid) | Yes | $100–250 |
| Replace the shift solenoid B | Mechanic | $200–500 |
Frequently asked questions
What does 'stuck off' mean?
The solenoid is physically held in its closed/off position, so it cannot open its fluid circuit. It is a mechanical problem rather than an electrical one.
Can a fluid change fix a stuck solenoid?
Sometimes, if the sticking is caused by sludge or debris. If the solenoid is worn, it will still need replacing.
How much does it cost to fix?
$100–250 for a fluid change, or $200–500 for a new solenoid.
