Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Identify Leak Source

Transmission Pan:
- Remove any underbody covers if present.
- Clean the area around the pan to identify the exact source of the leak.
Cooler Lines:
- Inspect both the inlet and outlet lines connected to the transmission for any signs of leakage.

3. Replace Seals or Lines

If the leak is from the pan:
- Drain the transmission fluid into a suitable container.
- Remove the transmission pan bolts using a socket set.
- Carefully remove the pan and replace the gasket.
- Reinstall the pan using the correct torque specifications (typically around 10-12 ft-lbs).
If the leak is from the cooler lines:
- Use an appropriate wrench to disconnect the leaking line.
- Replace the damaged line with a new one.
- Ensure all fittings are tight and secure.

4. Refill Transmission Fluid

Use the recommended transmission fluid (check the owner's manual for specifications).
Pour the fluid through the dipstick tube or filler plug until the correct level is reached.

5. Final Checks

Reconnect the battery.
Start the engine and let it idle for a few minutes.
Check for any leaks around the repaired areas.
