Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

• Remove the transmission dipstick and wipe it clean.
• Reinsert the dipstick, remove it again, and check the fluid level.
• If low, add the manufacturer-recommended transmission fluid until it reaches the correct level.
• If the fluid is dark or burnt, drain the old fluid using a drain pan and replace it with new fluid.

3. Inspect and Repair Wiring

• Visually inspect the wiring harness for the transmission control module and sensors.
• If damaged wiring or connectors are found, repair or replace as necessary.
• Use electrical contact cleaner on connectors to ensure good conductivity.

4. Test and Replace Transmission Range Sensor

• Locate the transmission range sensor and disconnect the wiring harness.
• Use a multimeter to test the sensor's resistance according to the manufacturer's specifications.
• Replace the sensor if it does not meet the specifications.

5. Check and Replace Vehicle Speed Sensor

• Locate the vehicle speed sensor, usually mounted on the transmission.
• Disconnect the electrical connector and remove the sensor using the appropriate socket.
• Install a new vehicle speed sensor and reconnect the electrical connector.

6. Clear Codes and Test Drive

• Reconnect the battery and use the OBD-II scanner to clear the P0730 code.
• Conduct a test drive to ensure the transmission operates smoothly and check for any reoccurring codes.
