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 transmission mechanical parts before testing the low shift solenoid A control circuit.
Useful checks before replacing parts
- Check shift solenoid A control wiring, internal harness, case connector, terminal tension, and short-to-ground faults.
- Compare solenoid command with circuit voltage or current and actual shift behavior.
- Review companion ratio, shift, and solenoid codes to understand whether the low circuit is causing limp mode.
