Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid pump, funnel, torque wrench.
Safety Warnings: Ensure the vehicle is on a level surface, and use wheel chocks to prevent rolling. Allow the engine to cool before working on the transmission.

2. Check CVT Fluid Level

Locate the CVT fluid dipstick or fill plug.
Remove the dipstick or plug and wipe it clean.
Reinsert it fully and remove again to check the fluid level.
If low, add the recommended CVT fluid until it reaches the proper level.

3. Inspect CVT Fluid Condition

Inspect the fluid on the dipstick for color and consistency.
If the fluid is dark brown or has a burnt smell, it needs to be replaced.
Drain the old fluid using a transmission fluid pump and replace it with fresh CVT fluid.

4. Inspect CVT Belt and Pulleys

Remove the access cover to the CVT belt area.
Visually inspect the CVT belt for cracks, fraying, or glazing.
Check the pulleys for wear and ensure they are aligned correctly.
If the belt shows signs of damage, it needs to be replaced.

5. Reassemble and Test

Reinstall any covers and ensure all components are secured.
Start the engine and allow it to reach operating temperature.
Conduct a road test to verify if the slipping issue has been resolved.
