Solution

1. Determine Change Frequency

Tesla recommends checking the transmission fluid every 50,000 miles or 4 years, whichever comes first, for normal driving conditions.
For severe driving conditions (e.g., frequent towing, racing), consider more frequent changes.

2. Inspect Transmission Fluid Condition

Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Remove the transmission fluid inspection plug (if applicable).
3. Check for metal shavings or discoloration in the fluid, which may indicate wear.

3. Change the Transmission Fluid (if necessary)

Sub-steps:
1. Lift the vehicle using a hydraulic lift or jack stands.
2. Place a drain pan under the transmission fluid pan.
3. Remove the drain plug and allow fluid to completely drain.
4. Replace the drain plug and torque it to the manufacturer's specification.
5. Use a funnel to refill the transmission with the recommended fluid type (Tesla uses its own proprietary fluid).
6. Start the vehicle and cycle through the gears to circulate the new fluid.
7. Check the fluid level using the inspection plug and add fluid as necessary.
