Hello, I have a 2004 echo (auto) and I want to change the auto-transmission oil after 200K kms When reading about this, watching videos etc, there seems to be a range of opinions on even whether to do the change or not?? My preference is to just do a simple drain and refill. Happy to let whatever metal bits have accumulated to be left trapped inside on the magnet. My guess is they won't be moving anywhere, but I'm happy to be corrected on that. However, I cannot find a specific video, or even manual picture, that identifies the exact plug that needs to be loosened in order to drain the fluid. Can someone pls supply a clear pic, or link, which shows the exact plug (nut) to loosen so the fluid will drain? Many thx, JB
