P0757
Shift Solenoid B Stuck On
Transmission — shift control
Generic OBD-II
Medium
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.
Medium
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.

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.
