Pan was dropped and filter changed. Pan was clean except for moderate residue on magnets. No debris on filter. I had the sample for just over a year before submitting it for analysis and no sediment settled out of it. Fluid was dark but did not smell burned. Refilled transmission, drove 10+ miles and did a drain and refill. Replacement fluid was Amsoil Universal. Shift quality was essentially unchanged and is still good after 4000 mi. Car is not driven hard and has 50+% highway miles.
