P0774 Shift Solenoid E Intermittent

P0774 points to an intermittent shift solenoid E fault. The transmission controller detected an unreliable solenoid E circuit or response.

Code details

Generic OBD-II · P0

System: Transmission
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace multiple solenoids without proving whether the intermittent fault is shared wiring or one solenoid path.

Symptoms of P0774

Harsh, delayed, or slipping shifts, or being stuck in one gear.
Check-engine light, sometimes with limp-home mode.
Flaring RPM or a shudder under load.

Common causes of P0774

Low or degraded transmission fluid.
A failing speed sensor, shift solenoid, or pressure-control circuit.
Wiring, connector, or internal hydraulic/mechanical faults.

Useful checks before replacing parts

Compare solenoid E command to actual shift behavior, speed sensor data, pressure data, and freeze-frame conditions.
Inspect internal harness routing, connector fluid intrusion, case connector terminals, solenoid resistance, and module driver output.
Review related pressure, ratio, or solenoid codes that may show a shared harness or hydraulic cause.
