Useful checks before replacing parts
- Measure manual control signal voltage, reference feed, ground, and continuity while operating upshift, downshift, and mode controls.
- Inspect switch contacts, connector terminals, short-to-ground faults, clock spring or shifter harness paths, and spilled-liquid damage.
- Compare low circuit status with manual mode entry, gear display, and related switch or range sensor data.
