Ended up doing very similar today. Used fluid pump to pull exactly 2qt out, dropped pan, just under 1qt remaining, cleaned magnet, wiped pan, replaced fluid. Filter looks like I should probably change soon. Don't have the correct tools for the filter seal, unless it's advised to leave the old one in there.

No abnormal amount of residuals on the pan magnet. Measured what was in there as I removed replaced with same, did the typical idle/drive/measure routine and we're in the goal posts, no top-off needed.

Shift seems better from 1st to 2nd, and dropdown after banging WOT seems faster also, but maybe it's all in my head. Will run it as-is until another oil change, then drop the pan and probably change filter and seal.

Is it worthwhile to swap the factory pan to one with a drain? Seem to be cheap enough and would be a lot less hassle than pumping out the dipstick.
