Your AOD is either very gummy vb or servos and possibly even governor.
but my bet is that it is time for a rebuild. The AOD and trucks never agreed with each other in stock form.
You are spouting the classic signs of OD band failure and even possible dirrect clutch failure.
However, I was able to once resurect an AOD by cleaning the vb up and the servo's to get it by - but not for long.
