Shift Solenoid E Performance or Stuck Off
The P0771 code means the vehicle's onboard diagnostic system has detected: Shift Solenoid E Performance or Stuck Off. This is a critical severity code.
- Keep driving?
- No -- stop driving
- DIY difficulty
- hard
- Estimated cost
- $150 - $600 (parts and labor)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.

Common Symptoms
- Check Engine Light illuminated
- Cannot shift into certain gears
- Transmission stuck in limp mode
- Harsh delayed shifts
Probable Causes (Ranked by Likelihood)
- Shift solenoid E stuck in off position Very High
- Clogged solenoid E from debris in fluid High
- Worn valve body bore for solenoid E Moderate
- Low transmission fluid pressure Low
Step-by-Step Diagnostic Procedure
-
Monitor shift solenoid E command vs actual state on scan tool
-
Check solenoid for mechanical sticking
-
Inspect transmission fluid for particles and contamination
-
Perform line pressure test
-
Replace solenoid E -- flush transmission if fluid is contaminated
Common Fixes by Vehicle
What techs usually find when diagnosing P0771 on specific vehicles — tap your vehicle for the fix and the exact part:
2005-2017 Toyota Camry/Highlander U250E/U151E Advanced DIY
Shift solenoid E performance on Toyota U-series transmissions affects the lockup and overdrive circuits. This solenoid sees the highest duty cycle and wears fastest. Replace the solenoid through the valve body. Toyota recommends checking the solenoid with a scan tool bidirectional test before replacement to confirm the solenoid is the issue and not a wiring fault.
Labor: 4-6 hours2007-2018 GM Silverado/Tahoe 6L80E Advanced DIY
Shift solenoid E on the 6L80E controls 5th-6th gear operation. Performance faults at highway speed often indicate solenoid wear or low line pressure. Check line pressure in all ranges before replacing solenoids. If pressure is low, the pump may be worn. If pressure is normal, replace the solenoid and check the valve body bore. GM TSB 17-NA-211 covers updated solenoid calibrations.
Labor: 4-6 hours2010-2019 Ford Escape/Fusion 6F35 Advanced DIY
The 6F35 SSE solenoid controls overdrive application. Performance codes on high-mileage 6F35 transmissions often indicate valve body bore wear. Ford updated the valve body casting on 2015+ models to address bore wear issues. On earlier models, a Sonnax oversized solenoid kit provides a permanent fix. Always replace the filter and fluid during the repair.
Labor: 5-7 hoursFrequently Asked Questions
Can I drive with code P0771?
Do not drive -- have the vehicle towed. Shift solenoid E performance or stuck off can cause the transmission to be stuck in the wrong gear or shift unpredictably.
What is shift solenoid E?
Shift solenoid E is an electro-hydraulic valve inside the transmission that controls fluid flow to engage specific gear combinations. It is commanded by the TCM to achieve proper shift timing.
Can I replace shift solenoid E without removing the transmission?
On most vehicles, shift solenoids are accessible by removing the transmission pan and sometimes the valve body. The transmission does not need to be removed from the vehicle.
