Inspect the transmission pan for metal shavings or debris.
Clean the pan and replace the filter if applicable.
Reattach the transmission pan, ensuring to torque the bolts to the manufacturer’s specifications (typically around 8-10 ft-lbs).

3. Add New Transmission Fluid

Using a funnel, add new Honda ATF DW-1 transmission fluid through the dipstick tube or designated fill port.
Check the fluid level with the dipstick, ensuring it is at the correct level while the vehicle is running and in park.

4. Test Operation
