Useful checks before replacing parts
- Compare manual shift control data with actual lever, button, or paddle operation and confirm each request is seen cleanly.
- Inspect switch wiring, shifter or steering-wheel connectors, clock spring paths where applicable, reference voltage, ground, and liquid damage.
- Check whether manual mode entry, gear display, upshift, or downshift request behavior matches the circuit fault.
