P0772 Shift Solenoid E Stuck On

P0772 indicates shift solenoid E is stuck on. The transmission behavior suggests the solenoid remains applied when the controller expects release.

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 the entire valve body before checking fluid debris, wiring, and solenoid E mechanical operation.

Symptoms of P0772

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 P0772

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

Monitor solenoid E command, actual ratio, input speed, output speed, and pressure data during the failed shift.
Check for contaminated fluid, stuck valve-body passages, solenoid sticking, wiring shorts, or control-driver issues.
Review related ratio, pressure, or shift-timing codes to identify the affected hydraulic path.
