P0745 Code: Pressure Control Solenoid A
🟠 Moderate severity · drivable
You can drive, but shifts may be harsh or delayed and the transmission could go into fail-safe mode.
What P0745 means
There's an electrical problem in the pressure control solenoid A circuit. This solenoid controls hydraulic pressure inside the transmission, and the computer uses it to make shifts smooth. An electrical fault here can cause harsh or slipping shifts.
Symptoms
- Check engine light is on
- Harsh or delayed shifts
- Transmission slips
- Transmission may go into fail-safe mode
Common causes
- most common: Faulty pressure control solenoid
- common: Damaged wiring or loose connector
- common: Contaminated transmission fluid
- less common: Low transmission fluid
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Check transmission fluid level and condition | Yes | $20–60 |
| Repair damaged wiring or connector | Mechanic | $80–250 |
| Replace pressure control solenoid A | Mechanic | $150–500 |
Frequently asked questions
Can I drive with a P0745 code?
Yes, but shifts may be harsh or delayed and the transmission could go into fail-safe mode. Have it diagnosed soon.
What does the pressure control solenoid do?
It controls hydraulic pressure inside the transmission. The computer adjusts it to make shifts smooth and to protect the clutches from slipping.
How much does it cost to fix a P0745?
Replacing pressure control solenoid A usually runs $150–$500 including parts and labor. Wiring repairs are typically less.
