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 assume the transmission is overheating until the temperature-sensor circuit and actual fluid condition are verified.
Useful checks before replacing parts
- Compare transmission fluid temperature to ambient temperature after a cold soak and to engine temperature after warm-up.
- Inspect transmission connector pins, internal harness, sensor circuit, grounds, and fluid intrusion at connectors.
- Check for related shift, pressure, or temperature codes that can change transmission strategy.
