P0759 Code: Shift Solenoid B Intermittent
🟠 Moderate severity · drivable
Usually drivable, but 2-3 shifts may be missed or rough when the solenoid signal drops out.
What P0759 means
Shift solenoid B's electrical signal comes and goes instead of staying steady. Because of this, the 2-3 shift works sometimes and fails other times. Loose wiring and bad connectors are the most common culprits for intermittent codes.
Symptoms
- Check engine light on and off
- Intermittent missed shifts
- Rough or delayed shifts at times
- Transmission occasionally slips
Common causes
- most common: Loose, corroded, or damaged wiring in the solenoid circuit
- common: Faulty shift solenoid B
- common: Low or dirty transmission fluid
- less common: Faulty transmission control module
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Clean and tighten the solenoid connector and inspect the wiring | Yes | $0–30 |
| Check and top up the transmission fluid | Yes | $20–60 |
| Replace shift solenoid B | Mechanic | $100–400 |
Frequently asked questions
Can I drive with a P0759 code?
Yes, but the transmission may miss or delay shifts at random times. Have the wiring checked soon.
Why does an intermittent code keep coming and going?
Because the electrical connection is failing on and off, often from a loose or corroded connector that moves while driving.
How much does it cost to fix a P0759?
A connector or wiring fix can be $30–$150, while replacing shift solenoid B runs $100–$400.
