Solution

1. Preparation

Tools Required: Socket set, torque wrench, fluid catch pan, clean rags, funnel.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical shorts.

2. Drain Transmission Fluid

Place the fluid catch pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan and allow the fluid to drain completely into the catch pan.

3. Inspect and Replace Gasket/Seals

Remove the old gasket from the transmission pan and the mating surface on the transmission.
Inspect the transmission seals and replace any that show signs of wear or damage.
Clean the surfaces thoroughly with a clean rag to ensure a proper seal.

4. Reinstall Transmission Pan

Place the new gasket onto the transmission pan.
Align the pan and install it back onto the transmission.
Tighten the bolts in a crisscross pattern to the manufacturer’s specified torque value (typically around 8-10 ft-lbs).

5. Refill Transmission Fluid

Using a funnel, refill the transmission with the appropriate type of fluid specified for the Tesla Outback (likely ATF).
Check the fluid level with the dipstick and add more if necessary.

6. Test for Leaks

Reconnect the battery.
Start the vehicle and allow it to reach operating temperature.
Check for leaks around the transmission pan and seals while the engine is running.
