Solution

1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Allow the engine to cool before beginning repairs.
Tools Required: Jack and jack stands, socket set, wrench set, fluid catch pan, screwdriver, and possibly a dye testing kit.

2. Identify and Fix Oil Leak

Sub-steps:
1. Clean the oil leak area with a degreaser to clearly see the source.
2. Tighten loose bolts on the oil pan or valve cover using a torque wrench.
3. Replace any damaged gaskets or seals (e.g., valve cover gasket).
4. If the oil pan is damaged, remove the pan, clean the surface, replace the gasket, and reinstall.
5. Refill the engine oil as necessary.

3. Address Coolant Leak

Sub-steps:
1. Inspect and replace any damaged hoses connected to the coolant reservoir.
2. If the radiator is leaking, remove it and install a new radiator.
3. Replace the thermostat if it's malfunctioning.
4. Refill the cooling system with the appropriate coolant.

4. Resolve Transmission Fluid Leak

Sub-steps:
1. Inspect the transmission pan for cracks or loose bolts; tighten or replace as necessary.
2. Replace the transmission pan gasket if it's leaking.
3. Refill transmission fluid to the proper level.
