Clean the Pan: Clean the transmission pan and its gasket surface thoroughly before reinstallation.

4. Fill with New Transmission Fluid

Access the Fill Port: Locate the transmission fluid fill port (typically on top of the transmission).
Use a Transmission Fluid Pump: Insert the pump or funnel into the fill port and begin adding new transmission fluid. Refer to the owner's manual for the correct type and amount of fluid (typically Honda ATF DW-1).
Check Fluid Level: After filling, check the fluid level using the dipstick while the engine is running and in park. Adjust as necessary.
