2. Replace the drain plug with a new washer and torque it to the manufacturer’s specifications.
3. Refill the transmission with the recommended CVT fluid using a funnel. Check the owner's manual for the correct fluid type and capacity.

3. Inspect and Replace CVT Components

Tools Required: Socket set, torque wrench, screwdrivers.
Sub-steps:
1. Remove any covers or shields to access the CVT assembly.
2. Inspect the CVT belt and pulleys for wear and damage.
3. If damaged, remove the belt and pulleys, and replace them with new OEM or quality aftermarket parts.
4. Reassemble all components and ensure proper torque specifications are met.

4. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the engine and allow it to reach operating temperature.
Test drive the vehicle to ensure smooth operation and no slipping or abnormal noises.
