Solution

1. Preparation

Park the vehicle on a level surface and set the parking brake.
Gather tools: OBD-II scanner, socket set, fluid pump, funnel, and a fluid catch pan.

2. Check and Replace Transmission Fluid

Inspect Fluid Level:
- Remove the transmission dipstick and wipe it clean.
- Reinsert, then remove again to check the fluid level; add fluid if low.
Change Fluid:
- Place a fluid catch pan under the transmission pan.
- Remove the transmission pan bolts using a socket set.
- Lower the pan carefully and drain the old fluid.
- Replace the transmission filter if applicable.
- Clean the pan and magnet, then reinstall with a new gasket.
- Refill with the appropriate transmission fluid (consult owner’s manual for specifications).

3. Inspect Transmission Components

Visual Inspection:
- Check for wear on gears and bearings by removing the transmission cover if accessible.
- Look for signs of damage to the torque converter.
Torque Converter Check:
- If noise persists, consider checking or replacing the torque converter as it can cause whining noises.

4. Test Drive

After repairs, perform a test drive under various conditions to ensure that the whining noise has been resolved.
