Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a flat surface and securely parked.
• Disconnect the vehicle from any charging source.

2. Update Software

• Connect the Tesla vehicle to Wi-Fi.
• Navigate to the software update menu and download any available updates.

3. Inspect and Replace Transmission Fluid

• Tools Required: Fluid pump, torque wrench, funnel.
• Check the fluid level using the designated dipstick or port.
• If low, add the recommended transmission fluid (consult the owner’s manual for specifications).
• If the fluid is dirty or contaminated, drain the old fluid:
  1. Locate the drain plug on the transmission.
  2. Position a drain pan underneath and remove the drain plug.
  3. Allow the old fluid to fully drain.
  4. Reinstall the drain plug and torque to manufacturer specifications.
  5. Use a fluid pump to fill the transmission with new fluid through the fill port until it reaches the recommended level.

4. Inspect Transmission Components

• Visually inspect the transmission for any signs of leaks or damage.
• Check electrical connections and wiring related to the transmission for wear or corrosion.
• If any components are damaged, proceed with their replacement.

5. Reassemble and Test

• Ensure all components are securely fastened.
• Reconnect the vehicle to the power source and allow it to charge if necessary.
• Perform a test drive to confirm that the slipping issue has been resolved.
