Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is turned off and cool.
Gather safety gear (gloves and safety glasses).

2. Locate the Transmission Drain Plug

Use a socket set to remove the undercarriage cover if applicable.
Identify the drain plug on the transmission pan.

3. Drain Old CVT Fluid

Place a drain pan under the transmission drain plug.
Remove the drain plug carefully using a wrench.
Allow the old CVT fluid to completely drain into the pan.

4. Replace the Drain Plug

Clean the drain plug and inspect the sealing washer for wear.
Reinstall the drain plug and torque it to the manufacturer-specified value (usually around 33 ft-lbs).

5. Refill New CVT Fluid

Locate the fill plug on the transmission (typically on top).
Using a funnel, add new CVT fluid (ensure it meets Honda specifications).
Fill until the fluid level reaches the desired mark (if using a dipstick) or until it starts to overflow slightly from the fill hole.

6. Check Fluid Level

Start the engine and let it idle for a few minutes.
Shift through all gears and return to park.
Check the fluid level again and add more fluid if necessary.
