- Refill with new CVT fluid (make sure it meets Honda specifications, such as Honda HCF-2).

3. Inspect and Clean Transmission Cooler

Sub-steps:
- Disconnect the lines from the transmission cooler.
- Inspect the cooler for debris or blockages and clean as necessary using compressed air.
- Reconnect the cooler lines ensuring no leaks occur.

4. Replace Transmission Filter (if equipped)

Sub-steps:
- Locate and remove the transmission filter.
- Install a new filter, ensuring it is seated properly.
- Reattach any fasteners securely.

5. Test Cooling System

Sub-steps:
- Check the coolant level and top off if necessary.
- Inspect hoses for leaks or damage.
- Start the engine and allow it to reach operating temperature while monitoring the temperature gauge.
