Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the battery to ensure safety during electrical work.

2. Drain Transfer Case Fluid

Locate the transfer case drain plug.
Use a socket set to remove the drain plug and allow the fluid to completely drain into a catch basin.
Inspect the drained fluid for metal shavings or debris, indicating internal wear.

3. Replace Transfer Case Fluid

Reinstall the drain plug and torque it to the manufacturer's specifications.
Locate the fill plug on the transfer case.
Using a fluid pump, fill the transfer case with new fluid that meets Honda specifications (typically Honda Dual Pump Fluid or equivalent).
Fill until the fluid starts to seep out of the fill hole, then reinstall the fill plug and torque to specifications.

4. Inspect and Replace Seals or Gaskets

Remove the transfer case from the vehicle if there are leaks or extensive damage.
Replace any worn or damaged seals and gaskets using an appropriate sealant.
Reinstall the transfer case, ensuring all bolts are torqued to specifications.

5. Test Transfer Case Functionality

Reconnect the battery.
Start the vehicle and engage the AWD mode; listen for abnormal noises and ensure smooth operation.
Perform a test drive to confirm that the issue has been resolved.
