Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, flashlight, rags, funnel.
Ensure the vehicle is parked on a level surface and the engine is cool before beginning any work.

2. Inspect and Repair Leaks

Sub-steps:
1. Check for Fluid Leaks: Look under the vehicle for any fluid leaks (oil, coolant, transmission fluid).
2. Tighten or Replace Seals: If leaks are found, tighten loose fittings or replace damaged seals and gaskets.
3. Clean Up Spills: Wipe any spilled fluids to prevent burning smells from contact with hot engine parts.

3. Change Oil and Filter

Sub-steps:
1. Drain Engine Oil: Remove the oil drain plug and allow oil to drain completely.
2. Replace Oil Filter: Use an oil filter wrench to remove the old oil filter; install a new filter with a dab of new oil on the gasket.
3. Refill Engine Oil: Replace the drain plug and fill the engine with the manufacturer-recommended oil type and quantity.

4. Inspect Brake System

Sub-steps:
1. Remove Wheel: Use a jack to lift the vehicle and remove the wheel to access the brake components.
2. Check Brake Pads and Rotors: Inspect for excessive wear or heat damage; replace if necessary.
3. Test Brake Components: Ensure calipers are not sticking and that brake lines are intact.

5. Address Transmission Issues

Sub-steps:
1. Check Transmission Fluid: Remove the dipstick and check fluid level and condition; top off or change fluid as necessary.
2. Inspect Transmission Cooler: Ensure the cooler is functioning correctly and there are no blockages.
3. Professional Inspection: If fluid is burnt, consider having a professional perform a transmission service.
