P0750 — Shift Solenoid A Malfunction
CAUTIONIs it safe to drive? Shift solenoid A has a problem. The transmission may stick in a gear or shift incorrectly — drive gently and address it.
What P0750 means
Shift solenoids open and close hydraulic circuits to change gears. Which gears are affected depends on make and model — check brand-specific diagrams. Often the solenoid itself fails due to dirty fluid.
Most likely causes (in order)
- Burnt or dirty transmission fluid clogging the solenoid
- Failed shift solenoid A
- Wiring or connector fault
- Valve body debris
Symptoms you might notice
- Stuck in gear
- Missing or incorrect shifts
- Limp mode
What to check first
Change fluid and filter first — solenoid sticking from dirty fluid is the #1 cause. Then test solenoid resistance and command it with a scanner to confirm it actuates.
