Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid pump, funnel, transmission fluid, safety glasses, gloves.
Ensure the vehicle is on a level surface and securely lifted using jack stands.

2. Transmission Fluid Check

Sub-steps:
1. Locate the transmission fluid dipstick or fill plug.
2. Remove the dipstick or fill plug using a socket set.
3. Check the fluid level; if low, add the appropriate type of transmission fluid as specified in the owner's manual.
4. Inspect the fluid condition; if it appears dark or burnt, a fluid change may be necessary.

3. Drive Belt Inspection

Sub-steps:
1. Visually inspect the drive belts for signs of wear, fraying, or cracks.
2. Check for proper tension and alignment.
3. If damaged, replace the drive belts with OEM or equivalent parts.

4. Transmission and Differential Inspection

Sub-steps:
1. If no issues are found with fluid levels, inspect the transmission for any external leaks.
2. Remove the fill plug from the differential and check the fluid level; add fluid if necessary.
3. Inspect for any unusual noises by rotating the wheels and listening for grinding or whining.

5. Reassembly and Testing

Sub-steps:
1. Reinstall the dipstick or fill plug securely.
2. Lower the vehicle safely from the jack stands.
3. Start the engine and conduct a test drive to ensure the whirring noise has been resolved.
