Diagnostic Steps

Solution

1. Preparation

Gather necessary tools: clean cloth, funnel (if adding fluid), and a flashlight.
Ensure the vehicle is in "Park" and on a level surface.

2. Access Transmission Fluid Fill Port

Open the front trunk and locate the transmission fluid fill port, which is typically near the rear of the motor compartment.
Remove the fill port cap carefully.

3. Check Fluid Level

Use a clean cloth to wipe the dipstick (if applicable) or observe the fluid level through the sight glass.
- If using a dipstick, insert it back into the fill port, then remove it again to check the level.
The fluid level should be within the recommended range marked on the dipstick or sight glass.

4. Add Fluid (if necessary)

If the fluid level is low, use a funnel to add the appropriate transmission fluid, typically Tesla's own or a suitable equivalent.
Add fluid in small increments, checking the level frequently until it reaches the correct level.

5. Replace Fill Port Cap

Ensure the fill port cap is securely fastened after checking or adding fluid.
