How do you change automatic transmission fluid on Honda Ridgeline?

To change the automatic Transmission Fluid on a Honda Ridgeline, start by warming up the engine, then turn it off and let it cool slightly. Locate the transmission fluid drain plug and remove it to drain the old fluid into a container. Replace the drain plug, then use a funnel to add new transmission fluid through the dipstick tube, checking the level with the dipstick to ensure it’s within the recommended range. Finally, start the engine, let it run for a few minutes, and check for leaks before taking the vehicle for a short drive and rechecking the fluid level.
