Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, transmission fluid, safety glasses, gloves, and a jack with stands.
Ensure the vehicle is on a flat surface and the engine is off.

2. Inspect Serpentine Belt

Sub-step 1: Open the hood and visually inspect the serpentine belt for cracks, fraying, or glazing.
Sub-step 2: If damaged, remove the belt by releasing tension from the tensioner pulley using a wrench.
Sub-step 3: Replace with a new serpentine belt, ensuring proper routing and tension.

3. Check Transmission Fluid

Sub-step 1: Locate the transmission dipstick (if equipped) or access the transmission fluid fill plug.
Sub-step 2: Check fluid level; if low, add the manufacturer-recommended transmission fluid.
Sub-step 3: Inspect for leaks around the transmission pan or cooler lines; repair any leaks found.

4. Inspect Transmission Components

Sub-step 1: If the whining persists, raise the vehicle and inspect the transmission for signs of wear or damage.
Sub-step 2: Check the condition of the output shafts and differential for play or wear.
Sub-step 3: If issues are found, consider replacing worn components or servicing the transmission.

5. Test Drive

Sub-step 1: After completing repairs, take the vehicle for a test drive to ensure the noise is resolved.
Sub-step 2: Monitor the performance of the vehicle, ensuring smooth acceleration and shifting.
