Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is warm but turned off.
Gather necessary tools: a clean cloth and a funnel if needed.

2. Access the Transmission Fluid

For Tesla vehicles, there is no traditional dipstick for checking transmission fluid. Instead, you will need to access the transmission fluid fill port.
Raise the vehicle using a jack and secure it with jack stands for safety.

3. Inspect Fluid Level

Locate the transmission fluid fill port, generally situated on the side of the transmission.
Remove the fill port cap. Use a clean cloth to wipe any debris off the cap and surrounding area.
Insert a funnel into the fill port to check the fluid level visually, or use a dipstick adapter if available. The fluid should be at the correct level as indicated in the manual.

4. Add Transmission Fluid (if necessary)

If the fluid is low, use the manufacturer's recommended transmission fluid type, as specified in the owner's manual.
Insert the funnel and slowly add fluid until it reaches the appropriate level.
Replace the fill port cap securely.
