P0747 Code: Pressure Control Solenoid A Stuck On
🟠 Moderate severity · drivable
You can drive, but shifts will be very harsh and the extra pressure can strain the transmission, so get it repaired soon.
What P0747 means
Pressure control solenoid A is stuck on, which keeps transmission line pressure high. High pressure makes shifts feel very harsh and jerky, and it puts extra strain on the transmission over time.
Symptoms
- Check engine light is on
- Very harsh or jerky shifts
- Rough engagement when shifting into gear
- Possible shudder during acceleration
Common causes
- most common: Faulty pressure control solenoid
- common: Valve body sticking
- common: Wiring short keeping the solenoid energized
- less common: Contaminated transmission fluid
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 |
| Repair shorted wiring or service the valve body | Mechanic | $200–800 |
