Solution

1. Preparation

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

2. Inspect and Replace Fluid

Transmission Fluid:
- Remove the transmission dipstick and check fluid level and condition.
- If fluid is low or burnt, add the appropriate type (refer to owner's manual).
- If fluid is contaminated, drain the transmission fluid and replace with new fluid.
Engine Oil:
- Check engine oil level using the dipstick.
- If low, top off with the correct oil type.
- If burnt, perform an oil change including oil filter replacement.

3. Brake Inspection and Replacement

Remove the wheel to access brake components.
Inspect brake pads and rotors for wear and overheating.
Replace worn brake pads or rotors as necessary using the following:
- Use a torque wrench to tighten lug nuts to manufacturer specifications.
- Reassemble the wheel and lower the vehicle.

4. Addressing Fluid Leaks

Identify and repair any fluid leaks found during the inspection.
Replace any faulty gaskets, seals, or hoses that may be causing leaks.

5. Final Inspection

Reconnect the battery and start the engine.
Allow the vehicle to idle and check for any unusual smells or leaks.
