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 to avoid any electrical issues.

2. Identify and Repair the Leak Source

For Engine Oil Leak:
- Inspect the oil pan and gasket for damage.
- Replace the oil pan gasket if necessary (remove the oil pan, clean the surface, apply new gasket, and torque to manufacturer specifications).
For Coolant Leak:
- Check the radiator, hoses, and connections for leaks.
- Replace damaged hoses or a faulty radiator (remove old components, install new parts, and refill coolant).
For Transmission Fluid Leak:
- Inspect the transmission pan and seals.
- Replace the transmission pan gasket if damaged (drain fluid, remove pan, clean surfaces, install new gasket, and refill transmission fluid).

3. Refill Fluids

After repairs, ensure all fluids (engine oil, coolant, transmission fluid) are at the correct levels as per the manufacturer’s specifications.

4. Final Inspection

Recheck all repaired areas for leaks after the vehicle has run for a brief period.
