P0771: Shift Solenoid E Performance/Stuck Off
2 vehicles · 1 makes · $150-$6,500 repair
Most Reported On
P0771 is an OBD-II diagnostic trouble code meaning “Shift Solenoid E Performance/Stuck Off.” This code indicates a performance problem with shift solenoid 'E', or that it appears stuck off — meaning the transmission isn't getting the gear engagement or behavior the computer commanded from that solenoid. Shift solenoids route hydraulic fluid to apply clutches and bands for specific gears, and on many transmissions solenoid E is tied to the torque converter clutch or a specific shift element. When the resulting action doesn't match the command, this code sets, often producing harsh or missing shifts, slipping, or a transmission limp mode. It generally points to the solenoid, fluid condition, or the valve body. This code is most commonly reported on 2019-2023 Ford Transit Connect, and 2022 Ford Maverick (XL, XLT, Lariat), with repair costs ranging from $150 to $6,500.
