P0774: Shift Solenoid E Intermittent
What to do
Note whether it happens when the car is thoroughly warm — that is the most common pattern, and it helps considerably.
What this code means
Solenoid E operates unreliably, producing brief protective shifts that clear themselves. Internal harness faults and pass-through connector leakage are the usual causes, and both are provoked by heat rather than by anything the driver does.
Likely causes
Start here
- Damaged transmission wiring harness · moderate
- Fluid tracking into the transmission connector · moderate
- Failed shift solenoid · moderate
Less common
- Corroded transmission connector · moderate

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
