2. Inspect the CVT belt for signs of wear, such as cracking, fraying, or glazing.
3. Check the pulleys for scoring or damage.
4. Measure the belt width and compare it with factory specifications to determine if it is worn down.

4. Replace Transmission Fluid (if necessary)

Sub-steps:
1. Place a drain pan under the transmission pan.
2. Remove the transmission pan bolts and carefully lower the pan.
3. Drain the old fluid and replace the transmission filter if applicable.
4. Reinstall the pan with a new gasket or sealant and torque the bolts to manufacturer specifications.
5. Refill the transmission with the correct type and amount of CVT fluid.
