P0746 Code: Pressure Control Solenoid A Performance/Stuck Off
🟠 Moderate severity · drivable
You can drive, but the transmission may slip or shift harshly, so avoid heavy acceleration until it's repaired.
What P0746 means
Pressure control solenoid A is not performing as expected and is likely stuck off. Line pressure may stay too low, which lets the clutches slip and makes shifts feel harsh or delayed. This is a performance fault rather than a pure electrical one.
Symptoms
- Check engine light is on
- Harsh or delayed shifts
- Transmission slips between gears
- Loss of power under acceleration
Common causes
- most common: Faulty pressure control solenoid
- common: Clogged valve body or filter screen
- common: Contaminated or low transmission fluid
- less common: Worn internal clutches
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Check transmission fluid level and condition | Yes | $20–60 |
| Replace pressure control solenoid A | Mechanic | $150–500 |
| Service the valve body or rebuild the transmission if clutches are worn | Mechanic | $800–3000 |
Frequently asked questions
Can I drive with a P0746 code?
Yes, but the transmission may slip or shift harshly. Avoid heavy acceleration and have it diagnosed soon to prevent further wear.
What does stuck off mean for a pressure control solenoid?
It means the solenoid isn't holding line pressure like it should, so transmission pressure stays too low. That lets the clutches slip and makes shifts feel harsh.
How much does it cost to fix a P0746?
Replacing the solenoid usually runs $150–$500. If the valve body or clutches are damaged, repairs can run $800–$3,000.
