Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, CVT fluid level gauge, safety goggles, gloves
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Change CVT Fluid

Locate the CVT fluid drain and fill plugs.
Using a socket set, remove the drain plug and allow the fluid to drain completely into a suitable container.
Replace the drain plug and torque it to the manufacturer’s specifications (check service manual for exact torque values).
Remove the fill plug and use a fluid level gauge to fill with the appropriate CVT fluid until it reaches the specified level.
Reinstall the fill plug and torque it to manufacturer specifications.

3. Inspect CVT Belt and Pulleys

Remove necessary covers to access the CVT assembly.
Visually inspect the CVT belt for fraying, glazing, or cracks.
Check the pulleys for wear and tear, ensuring they are clean and free from debris.
If significant wear is present, proceed to replace the CVT belt and pulleys as needed.

4. Reassemble and Test

Reinstall any covers removed during inspection and ensure all bolts are secured.
Reconnect the battery.
Start the vehicle and allow it to idle while checking for any leaks around the transmission area.
Conduct a test drive to ensure proper operation and monitor for any slipping symptoms.
