Solution

1. Preparation

Tools Required:

- Oil catch pan
- Clean rags
- UV dye kit (if needed)
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool and disconnect the battery.

2. Identify the Source of the Leak

Use a UV light if dye was added to the transmission fluid to pinpoint the leak.
Clean the transmission area with a degreaser to ensure a clear view of leaks.

3. Repair the Leak

For Transmission Pan Gasket:
1. Drain the transmission fluid into an oil catch pan.
2. Remove the bolts securing the transmission pan using the socket set.
3. Carefully pry the pan off and remove the old gasket.
4. Clean the mating surfaces of the pan and transmission with a clean rag.
5. Install a new gasket and reattach the pan, torquing the bolts to manufacturer's specifications (consult repair manual for specific torque values).
For Seals and Lines:
1. If the leak is from the output shaft seal, remove the driveshaft if necessary.
2. Use a seal puller to remove the old seal and install a new one.
3. Tighten any loose fittings on the transmission cooler lines and replace any damaged lines.

4. Refill Transmission Fluid

Refill the transmission with the appropriate type of transmission fluid as specified by Tesla (consult the owner's manual for details).
Use the dipstick to check the fluid level and ensure it is at the correct mark.

5. Final Checks

Reconnect the battery and start the vehicle.
Allow the engine to reach operating temperature and check for leaks again.
