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 transmission assembly before checking solenoid D operation and valve-body contamination.
Useful checks before replacing parts
- Monitor solenoid D command, actual ratio, input speed, output speed, and pressure data during the affected gear change.
- Check for debris, fluid contamination, valve-body sticking, solenoid mechanical sticking, or wiring shorts.
- Use related shift and ratio codes to narrow the hydraulic circuit involved.
