i finally got around to changing out the PTU fluid. I'm at 31100 miles.
the fill plug was full of a nice paste with lots of glitter!
the oil came out pure black with a bit of glitter but it was still a nice liquid. i was able to get around 13 oz out. i used a small hose with adapter on my vacuum pump and it worked quit well.
i also did a drain and fill on the tranny and had to fix a tire with a nail in it.
