Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is cool.
Safety: Disconnect the battery to prevent any electrical issues.

2. Drain Old Transmission Fluid

Locate the transmission drain plug under the vehicle.
Use a socket set to remove the drain plug and allow the old fluid to completely drain into a catch pan.
Replace the drain plug once all fluid has drained.

3. Replace Transmission Filter (if applicable)

Remove the transmission pan by unscrewing the bolts with a socket set.
Carefully detach the pan to access the filter.
Remove the old filter and replace it with a new one, ensuring it is securely seated.

4. Add New Transmission Fluid

Identify the correct type of transmission fluid specified by the manufacturer (e.g., TESLA ATF).
Use a funnel to refill the transmission with new fluid through the dipstick tube until it reaches the correct level.
Start the engine and allow it to idle, then cycle through all gears to distribute the fluid.

5. Check for Leaks

Inspect around the transmission pan and drain plug for any signs of leaks after adding new fluid.
If leaks are present, recheck the tightness of the pan bolts and drain plug.

6. Finalize and Test Drive

Reconnect the battery.
Take the vehicle for a short test drive to ensure smooth operation and proper shifting.
