P0774 — Shift Solenoid E Malfunction
Drivable short-term, but fix now to avoid damage.
What P0774 means
This code means the powertrain computer detected that shift solenoid E is malfunctioning and not responding as expected, so the transmission can't shift properly. It usually points to a failed solenoid, dirty transmission fluid, wiring issues, or a worn valve body. It's commonly fixed by replacing the solenoid and servicing the fluid, and most repairs avoid a full transmission rebuild.
Common symptoms
- Check engine light is on
- Harsh or delayed gear changes
- Transmission stuck in gear or in limp mode
- Slipping or RPMs flaring during shifts
- Reduced fuel economy
Common causes
- Failed or worn shift solenoid E
- Dirty or low transmission fluid
- Damaged wiring or connector to the solenoid
- Faulty valve body
- Transmission control module fault
Typical repair cost
$250 – $800
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0774 code?
For short trips, usually yes, but you shouldn't rely on it. A malfunctioning shift solenoid can cause harsh shifts or limp mode and added transmission wear, so have it checked soon.
How much does it cost to fix a P0774 code?
Most repairs run between about $250 and $800, depending on whether you need just a solenoid and fluid service or also valve body or wiring work.
Is a P0774 code serious?
It can be. The car may still move, but a faulty solenoid affects shifting and can lead to more expensive damage if ignored, so it's best to address it promptly.
What does shift solenoid E do?
Shift solenoid E is an electronically controlled valve that routes transmission fluid to engage the correct gear. When it malfunctions, the transmission can't shift as designed, which sets this code.
