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 condemn the transmission for overheating until the temperature circuit and actual fluid temperature are verified.
Useful checks before replacing parts
- Check for open circuits, poor grounds, connector damage, internal harness faults, or a temperature signal stuck high.
- Compare scan-tool fluid temperature with actual operating conditions and other temperature sensors.
- Inspect transmission connector sealing, pin fit, and harness routing around heat and fluid exposure.
