Replace Fluid (if discolored):
- Drain the old transmission fluid by removing the drain plug.
- Replace the drain plug and refill with new fluid through the dipstick tube.

3. Inspect and Repair Transmission Components

Inspect for Leaks:

- Replace any damaged gaskets or seals.
Check Internal Components:
- If the whining persists, consider removing the transmission pan for internal inspection.
- Look for worn gears, bearings, or any debris in the pan.
