Solution

1. Preparation

Tools Required:

Ensure the vehicle is parked on a level surface and the engine is off. Wear safety gloves and goggles.

Use a socket wrench to remove the fill plug from the transfer case.
Inspect the condition of the plug and its washer. Replace if damaged.

3. Check Fluid Level

Insert a clean finger or a dipstick into the fill hole to check the fluid level.
The fluid should be level with the bottom of the fill hole. If not, prepare to add fluid.

4. Add Transfer Case Fluid

If fluid needs to be added, select the appropriate Honda transfer case fluid (check owner’s manual for specifications).
Using a funnel, carefully add fluid until it begins to slightly overflow from the fill hole.

5. Reinstall Fill Plug

Clean the fill plug and the washer, then reinstall it into the transfer case.
Tighten the fill plug to the manufacturer’s specified torque value (consult the owner’s manual for the specific value).
