...I read a discussion a few days ago that it was better to remove the trans and drain all the fluid, no doubt that's true. This is just easier and I don't see how it can be bad as long as I'm careful to clean around the hole before removing the plug. The oil is black but doesn't smell burnt, I'll replace it with 20w-50.

I would go so far as saying it was FUN doing the complete drain & fill, because it forces you to clean, inspect, lube and adjust several other things while you're at it
AND nothing beats the feeling of having the hydrostatic full of fresh fluid, almost like the day it was assembled, :tango_face_wink:
*** For a partial drain & fill, there's only a couple things to watch out for. Clean around the filler hole, replace EXACTLY the volume you took out, and use a tiny plastic hose to suck the air out of the expansion tank, which allows the last several ounces (300ml) to flow in. Because you haven't really drained all the fluid, purging may not be too hard.
Like you said, even though the fluid may have been 'roasted' many times, it doesn't smell. It just looks like metalized, liquid ? :tango_face_glasses:
