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 whole valve body without checking whether the stuck-on symptom is from wiring, debris, or a single solenoid.
Useful checks before replacing parts
- Monitor solenoid C command, actual gear, calculated ratio, input/output speeds, and pressure data during the failed shift.
- Check for contaminated fluid, valve-body sticking, solenoid mechanical sticking, wiring shorts, or control-driver faults.
- Look for companion incorrect-ratio or shift-timing codes that identify the affected gear path.
