Shift Solenoid B Stuck On
What it means
P0757 means shift solenoid B is stuck on — staying energized or open when it should release — so the transmission cannot change gears normally. It may stay locked in one gear or shift harshly. The engine still starts and runs, but the transmission often drops into a protective limp mode until the solenoid or its circuit is fixed.
Can I keep driving? The car still drives, but a stuck shift solenoid often forces the transmission to hold one gear or drop into limp mode — drive gently and get it repaired soon.
Real-world scan data

Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

How to diagnose & fix
Work through it in order
- Confirm the code and read freeze-frame data.
- Check transmission fluid level and condition — dirty fluid can stick solenoids.
- Inspect the solenoid B wiring and connector for damage or corrosion.
- Test the solenoid resistance and operation; replace it if faulty.
- If it persists, inspect the valve body and TCM. Clear and re-test.
