Case in point, the Vette is turning 140K tomorrow, maintenance book shows it got a full trans rebuilt at 120ish but I will still only drop the pan, change filter and keep going. Just the way I do it lol.
On the diesels I had it was simple, the pan had a drain plug in it. I would drain them at 12K and refill, then change filter every other drain.
