Useful checks before replacing parts
- Check manual mode signal voltage, ground path, open circuits, short-to-voltage faults, connector fit, and switch transition data.
- Inspect shifter wiring, console connectors, spilled-liquid damage, recent trim work, and related upshift or downshift inputs.
- Compare high input behavior with manual mode entry, gear display, range sensor data, and freeze-frame voltage conditions.
