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 an electrical failure when the code says performance; hydraulic response and fluid condition must be checked.
Useful checks before replacing parts
- Compare shift solenoid F command with actual gear ratio, shift timing, input speed, output speed, and pressure data.
- Inspect fluid condition, valve-body sticking, solenoid response, control wiring, and connector condition.
- Review whether the fault occurs hot, cold, during one shift, or under heavy throttle.
