Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, transmission fluid, funnel, and rags.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Check and Replace Transmission Fluid

Locate the Transmission Dipstick: Open the hood and locate the transmission dipstick.
Check Fluid Level: Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
- Tools Required: None for this step.
Inspect Fluid Condition: If the fluid appears dark or has a burnt smell, it needs to be replaced.
Drain Old Fluid: Position a drain pan under the transmission pan and remove the drain plug. Allow the old fluid to completely drain.
- Safety Warning: Ensure the vehicle is cool to avoid burns from hot fluid.
Replace Filter: If applicable, remove the transmission pan and replace the filter.
- Torque Specification: Ensure to torque pan bolts to manufacturer specifications (usually around 10-12 ft-lbs).
Add New Fluid: Using a funnel, add the appropriate type and amount of new transmission fluid as specified in the owner’s manual.
- Fluid Type: Refer to the owner's manual for the specific fluid type (e.g., Hyundai SP-IV).
Check for Leaks: Start the engine and allow it to run while checking for any leaks around the transmission pan and drain plug.

3. Inspect and Repair Components

Inspect Transmission Mounts: Check for signs of wear or damage to the transmission mounts. Replace if necessary.
Examine Belt and Pulleys: If the whining persists, inspect the serpentine belt and pulleys for wear. Replace any worn components.
