P0771
Shift Solenoid E Performance/Stuck Off
Transmission (shift solenoid)
Generic OBD-II
Medium
What it means
P0771 means shift solenoid E is under-performing or stuck in the "off" (released) position, so the hydraulic circuit it controls isn't applying as commanded. Shifts into the affected gear may be delayed, slipping, or missing, and the transmission may enter a failsafe mode. Low or dirty fluid and a worn solenoid are the usual causes.
Medium
Can I keep driving? Drivable but expect poor or missing shifts and the transmission may hold one gear; fix soon to avoid clutch wear from slipping.
Common symptoms
What you'll notice
- Transmission slipping or not shifting properly
- Delayed or harsh shifts
- Stuck in the wrong gear (limp mode)
- Check-engine light on
Common causes
Most likely first
- Shift solenoid E stuck off or worn (weak performance)Likely
- Low or contaminated transmission fluid reducing hydraulic pressureCommon
- Damaged wiring or a poor connector in the solenoid circuitCommon
- Blocked or worn valve-body passagesLess often
- Failed transmission control module (less common)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame and check transmission fluid level and condition first.
- Service low or dirty fluid and the filter.
- Inspect the solenoid E wiring and connector.
- Test and replace shift solenoid E if it fails to actuate.
- Inspect the valve body for sticking if the solenoid is good.
FAQ
Quick answers
Is it safe to drive with P0771?+
Short trips are usually fine, but slipping and holding the wrong gear generate heat that wears the clutches, so repair it soon.
Can I just clear P0771?+
It returns until the solenoid, fluid, or valve-body problem is corrected — the transmission keeps detecting that the circuit isn't applying as commanded.
