Still didn't look very red. No improvement to slight hesitation on gear change. Needs to have counter reset and maybe adaptions etc.

I would advise going for a drive inbetween flushes so the fluid is thoroughly mixed. Or - sump dump and fill, drive around normally for a day or so depending on how much you use the car, say 50-100 miles then do it again. I have found this much better than sequential dumps just cycling through the gears without driving anywhere.
