Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, transmission fluid, funnel, drain pan, OBD-II scanner.
Park the vehicle on a level surface and engage the parking brake.

2. Inspect and Replace Transmission Fluid

Check Fluid Level:
- Remove the dipstick and wipe it clean. Reinsert and remove it again to check the fluid level.
- If low, add the appropriate type of transmission fluid as specified in the owner’s manual.
Drain Old Fluid:
- Place a drain pan under the transmission pan.
- Remove the pan bolts with a socket set and allow the fluid to drain completely.
Replace Filter:
- Remove the old filter from the transmission and install a new one, ensuring it is seated properly.
Reinstall Transmission Pan:
- Clean the mating surface of the pan and apply a new gasket if necessary.
- Reinstall the pan and tighten bolts to the manufacturer’s specified torque.

3. Inspect Transmission Components

Check for Wear:
- Inspect gears and bearings inside the transmission for wear or damage.
- Look for signs of metal shavings in the fluid.
Listen for Noise:
- With the vehicle running, listen closely to pinpoint the source of the whining noise.
- If noise persists, further disassembly may be needed.

4. Address Drive Belt and Pulleys

Inspect Drive Belt:
- Check the drive belt for cracks or wear, replacing it if necessary.
Check Pulleys:
- Inspect the pulleys for alignment and wear. Replace any faulty components.
