Solution

1. Preparation

Gather tools and materials:
- Floor jack and stands
- Socket set
- Torque wrench
- Clean rags
- UV dye kit (if necessary)
Ensure a clean workspace and safety gear (gloves and goggles).

2. Lift the Vehicle

Use the floor jack to raise the vehicle securely and place it on jack stands.
Ensure the vehicle is on a level surface for accurate inspection.

3. Inspect the Transmission Pan

Locate the transmission pan and check for any visible damage or loose bolts.
If leaks are detected:
- 3.1. Drain the transmission fluid by removing the pan bolts and carefully lowering the pan.
- 3.2. Clean the pan and inspect the gasket.
- 3.3. Replace the gasket if damaged and reinstall the pan. Torque the bolts to manufacturer specifications (typically around 10-12 ft-lbs).

4. Check the Transmission Cooler Lines

Inspect the cooler lines connected to the transmission.
4.1. If leaks are found:
- 4.1.1. Loosen the fittings with a wrench.
- 4.1.2. Replace damaged lines with new ones and ensure tight connections.

5. Add UV Dye (if necessary)

If leaks are not visible, add UV dye to the transmission fluid.
Run the engine for a few minutes and check under the vehicle with a UV light to identify the source of the leak.
