Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, jack and jack stands, basic hand tools (sockets, wrenches), brake cleaner.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Allow the engine to cool before proceeding.

2. Addressing Fluid Leaks

Identify the source of any fluid leaks found during the diagnostic step.
If the leak is from oil, coolant, or brake fluid, replace the damaged seals, gaskets, or hoses as necessary.
Clean up any spilled fluids with brake cleaner to prevent further burning smells.

3. Brake Inspection and Repair

Remove the wheel to access the brake caliper and rotor.
Inspect the brake pads for wear; if worn down to the backing plate, replace them.
Check the rotor for warping or overheating; replace if necessary.
Reassemble the brake components and wheel, ensuring all bolts are torqued to manufacturer specifications.

4. Replace Damaged Belts and Hoses

Identify any frayed or damaged belts and hoses during inspection.
Use a socket to loosen the tensioner, then remove the belt.
Replace any damaged belts with new ones, ensuring proper routing.
Inspect and replace any damaged hoses, securing them with the appropriate clamps.

5. Testing the Transmission

Check the transmission fluid level with the dipstick while the vehicle is running.
If the fluid is burnt or low, replace it with the manufacturer-recommended fluid.
If the transmission is overheating, further diagnostic may be required to address internal issues.
