P0771

Shift Solenoid E Performance/Stuck Off

Q: 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.

Q: 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.

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 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.
