2. Drain Old CVT Fluid

Tools Required: Socket set, oil drain pan, funnel, and CVT fluid.
Locate the transmission fluid drain plug under the vehicle.
Position the oil drain pan beneath the drain plug.
Remove the drain plug using the socket set and allow the old fluid to drain completely.
Replace the drain plug and torque it to the manufacturer's specification (usually around 30 ft-lbs).

3. Replace CVT Fluid Filter (if applicable)

Tools Required: Screwdriver, oil filter wrench.
Locate the CVT fluid filter (consult the service manual for specific location).
Remove the old filter using the oil filter wrench or screwdriver.
Install the new CVT fluid filter, ensuring it’s properly seated.

4. Fill New CVT Fluid

Tools Required: Funnel.
Locate the CVT fluid fill plug.
Remove the fill plug and insert the funnel.
Pour in the manufacturer-recommended CVT fluid until it reaches the proper level (check specifications for the exact amount).
Reinstall the fill plug and torque it to the specified value.

5. Final Checks

Reconnect the battery negative terminal.
Start the engine and let it idle for a few minutes.
Shift through all transmission gears to circulate the new fluid.
Check for leaks around the drain and fill plugs.
