Oh also, the tranny is the GM (my anti-Obama brother calls them "Government Motors") 4L30E so it's not one of the ZF units. The Isuzu Trooper crowd seems to have posted generously on how to get the fluid level correct. When it cavitates, it makes no sound, just falls into a neutral state for a moment.
On the windows, all 4 don't work (and yes they could all be stuck from 3 years) the moonroof doesn't and the central locking doesn't either. So I need to get after the fuse checking.
