Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues.

2. Identify and Fix the Leak Source

For Coolant Leak:
1. Remove the engine cover (if applicable) using a socket set.
2. Inspect the radiator and hoses for cracks or loose connections.
3. Replace damaged hoses or radiator if necessary.
For Oil Leak:
1. Inspect the oil pan and drain plug for leaks.
2. Tighten the drain plug or replace the oil pan gasket if leaking.
For Transmission Fluid Leak:
1. Inspect the transmission pan and seals.
2. Replace any damaged gaskets or seals in the transmission assembly.

3. Replace Any Necessary Components

If damaged components are found, replace them with OEM or quality aftermarket parts.
Ensure all connections are tight and secure.

4. Refill Fluid Systems

Refill any drained fluids to appropriate levels (engine oil, coolant, transmission fluid).
Use the manufacturer's specified fluids for refilling.

5. Final Inspection

Reconnect the battery.
Start the vehicle and allow it to reach operating temperature while checking for leaks.
Monitor the fluid levels and ensure they remain stable.
