Solution

1. Preparation

Tools Required:
- Torque wrench (if applicable)
- Clean funnel (if adding fluid)
- Rags (for cleanup)
Safety Warnings:
- Ensure the vehicle is parked on a level surface and is in 'Park'.
- Allow the vehicle to cool down before checking fluid levels.

2. Access Transmission Fluid Check Point

Locate the transmission fluid fill port under the vehicle near the transmission assembly.
If needed, raise the vehicle using a jack and secure it with jack stands.

3. Check Fluid Level

Remove the fill plug using the appropriate wrench (if applicable).
Insert a clean funnel into the fill hole to avoid spills.
Check the fluid level; it should be at the fill hole's bottom edge. If fluid drips out, the level is sufficient.

4. Add Fluid (if necessary)

If the fluid level is low, using a clean funnel, add the recommended transmission fluid type (Tesla recommends using their own branded fluid).
Add fluid slowly to avoid overfilling and check the level frequently.

5. Reassemble

Replace the fill plug securely and tighten to the manufacturer’s torque specifications if applicable.
Clean any spills with rags to prevent contamination.
