Tools Required: Fluid extraction pump, catch pan.
Use a fluid extraction pump to remove the old CVT fluid from the transmission.
Ensure the catch pan is positioned correctly to avoid spills.

3. Remove Transmission Pan

Tools Required: Socket set, torque wrench.
Remove the bolts securing the transmission pan using a socket set.
Carefully lower the pan and inspect the filter; replace if necessary.

4. Inspect and Replace CVT Belt

Tools Required: Pulley puller, socket set, torque wrench.
Use the pulley puller to remove the drive pulleys.
Carefully take out the old CVT belt and inspect the sheaves for wear or damage.
Install the new CVT belt, ensuring it is properly seated on the pulleys.

5. Reassemble Transmission

Reinstall the transmission pan and tighten the bolts to the manufacturer’s specified torque settings.
Refill the transmission with new CVT fluid according to the manufacturer’s specifications.

6. Final Checks

Reconnect the battery and start the engine.
Allow the engine to idle for a few minutes and check for leaks.
