Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, torque wrench, transmission fluid, funnel, and replacement CVT filter if necessary.
Ensure the vehicle is on a level surface and securely lifted if needed.
Disconnect the battery to ensure safety during the repair.

2. Check and Replace Transmission Fluid

Fluid Level Check
- Locate the CVT fluid dipstick or fill port.
- Remove the dipstick, wipe it clean, reinsert it, and remove it again to check the fluid level.
- If low, top off with the manufacturer-recommended CVT fluid.
Fluid Change
- If the fluid is burnt or contaminated, drain the old fluid from the transmission pan.
- Remove the transmission pan bolts and gently pry off the pan. Be cautious of any fluid still in the pan.
- Replace the filter if applicable and clean the mating surface.
- Reinstall the pan and torque the bolts to manufacturer specifications.
- Fill the transmission with new CVT fluid using a funnel through the dipstick or fill port.

3. Inspect and Replace CVT Components

Belt and Pulleys Inspection
- Remove any necessary covers to access the CVT belt and pulleys.
- Inspect for signs of wear, cracks, or fraying on the CVT belt.
- Check the pulleys for any scoring or damage.
If damaged, replace the CVT belt and/or pulleys according to manufacturer specifications.
