Yah, I hear you. I dropped the pan just to clean the magnets and get as much old fluid out as possible. I heard bad things about that o-ring so went to the dealer to get one "6 weeks, not stocked" It finally came in 4 days ago so I just flushed the screen out with brake cleaner and changed the paper filter. Pulling the fender liner is a pain in the crack but well worth it. 4 litres of old fluid out, 4 litres in, no leak.
