1. Preparation

Gather tools and parts for the repair.
Disconnect the vehicle battery to avoid electrical shorts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.

2. Fluid Change

Sub-steps:
1. Place a drain pan under the transmission pan.
2. Remove the transmission pan bolts using a socket set.
3. Carefully lower the pan and allow the old fluid to drain completely.
4. Replace the transmission filter (if applicable) and inspect the pan for debris.
5. Clean the pan and replace the gasket.
6. Reinstall the pan using the torque specifications provided in the service manual (typically 10-12 ft-lbs).

3. Repair or Replace Range Sensor

Sub-steps:
1. Locate the transmission range sensor on the transmission.
2. Disconnect the electrical connector and remove the mounting bolts.
3. Install the new range sensor by reversing the removal steps.
4. Reconnect the electrical connector securely.

4. Wiring Inspection

Sub-steps:
1. Visually inspect wiring harness and connectors for any signs of damage or corrosion.
2. Use a multimeter to test the continuity of the wires.
3. Repair or replace any damaged wiring or connectors.

5. Test Drive

Sub-steps:
1. Reconnect the battery and clear any diagnostic trouble codes.
2. Start the engine and allow it to reach normal operating temperature.
