2. Remove the retaining bolts of the CVT filter and detach the filter from the transmission.
3. Install the new CVT filter, ensuring a proper seal and secure with bolts.
4. Reinstall any underbody shields removed.

4. Inspect and Replace Torque Converter (if necessary)

Tools Required: Socket set, torque wrench, jack stands
Steps:
1. Remove the transmission from the vehicle by unbolting it from the engine and disconnecting all necessary wiring and fluid lines.
2. Once removed, inspect the torque converter for damage or wear.
3. Replace the torque converter if it is faulty by following the manufacturer’s installation guidelines.
