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.
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.
