Solution

1. Preparation

Tools Required: OBD-II scanner, torque wrench, socket set, fluid catch pan, funnel, CVT fluid (Honda HCF-2), multimeter.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace CVT Fluid

Sub-steps:
1. Place a fluid catch pan under the transmission drain plug.
2. Remove the drain plug and allow the old CVT fluid to fully drain.
3. Replace the drain plug and tighten it to the manufacturer’s specifications (typically around 30 Nm).
4. Using a funnel, refill the transmission with Honda HCF-2 CVT fluid through the fill tube to the specified level.

3. Inspect and Replace the CVT Belt

Sub-steps:
1. Remove any necessary components to access the CVT belt (such as the engine cover).
2. Remove the belt cover bolts and take off the cover.
3. Inspect the CVT belt for wear or damage; if necessary, remove the belt from the pulleys.
4. Install the new CVT belt by routing it over the pulleys and ensuring it is seated correctly.
5. Reinstall the belt cover and secure it with the bolts, tightening to specifications.

4. Final Testing

Sub-steps:
1. Reconnect the battery.
2. Start the engine and allow it to idle.
3. Conduct a road test to ensure that the slipping symptoms are resolved and monitor for any unusual noises or performance issues.
