Solution

1. Preparation

Gather necessary tools and park the vehicle on a level surface.
Allow the engine and transmission to cool to avoid burns.
Disconnect the battery to prevent electrical shorts.

2. Identify Leak Source

Tools Required: Flashlight, inspection mirror
Use the flashlight and inspection mirror to pinpoint the exact location of the leak.
If the leak originates from the transmission pan, prepare for removal.

3. Remove Transmission Pan

Tools Required: Socket set, torque wrench, gasket scraper
Remove the bolts securing the transmission pan using the socket set.
Carefully lower the pan and drain any remaining fluid into a pan for disposal.
Clean the mating surface on the transmission case with a gasket scraper.

4. Replace Gasket or Seal

If the gasket is damaged, replace it with a new one. Ensure the new gasket is compatible with the Tesla Model Y.
For seals, remove the old seal and install a new one, ensuring it is seated correctly.

5. Reassemble Transmission Pan

Reinstall the transmission pan over the transmission.
Torque the pan bolts to the manufacturer's specifications (typically around 10-12 ft-lbs but verify for your specific model).
Reconnect the battery.

6. Refill Transmission Fluid

Tools Required: Funnel, transmission fluid (Tesla-approved type)
Using a funnel, refill the transmission with the appropriate fluid until it reaches the correct level.
Start the vehicle and cycle through the gears to ensure proper fluid distribution.
