Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool down if recently driven.

2. Drain Old Transmission Fluid

Locate the transmission fluid drain plug, usually found on the bottom of the transmission pan.
Using a socket set, remove the drain plug and allow the old fluid to fully drain into a suitable container.
Replace the drain plug and torque it to the manufacturer’s specifications.

3. Remove the Transmission Filter

If applicable, remove the transmission pan to access the filter.
Unbolt the transmission pan using a socket set and gently pry it off.
Remove the old filter and replace it with a new one, ensuring that the sealing surface is clean.

4. Add New Transmission Fluid

Using a funnel, pour the recommended type and quantity of new transmission fluid into the transmission fill port.
Refer to the owner’s manual for specific fluid type (e.g., Tesla-approved fluid) and capacity.

5. Check Fluid Level and Test Drive

Start the vehicle and let it idle for a few minutes while shifting through all gears.
Check the fluid level again, adding more fluid as necessary until it reaches the correct level.
Test drive the vehicle to ensure smooth operation.
