Step 2: Replace the transmission fluid filter if applicable (consult service manual for procedure).
Step 3: Refill the transmission with the recommended type of fluid.
- Fluid Type: Honda ATF DW-1 or equivalent.
Step 4: Start the engine and cycle through the gears to allow fluid to circulate, then check the fluid level again and adjust as necessary.

4. Inspect and Repair Drive Train Components

Step 1: Raise the vehicle and secure it on jack stands.
Step 2: Inspect the drive shafts and CV joints for any signs of wear or damage; replace if necessary.
Step 3: Check for any play in the wheel bearings or hubs; replace if needed.
