OK. Here goes.
On jack stands all day. Looked and tugged and hit everything. Everything is perfect. All bolts, nuts are tight with no sign of wobbling, etc.
It only does it under acceleration from a stop and if you're on it when it shifts.
So........ Put my wife in back seat and drove it. 50-75% gone!!!
No noise when shifting-only a little bit left when I hit it off the line. Wife stuffed towels between seat edge and panel and sat on driver side in rear.
Noise is gone !!!!!
Put her in front and left towels. Only a fraction of noise left.
Almost sounds like (now) a big socket or steel ball is banging between the well and the 1/4. Took off the vent screen in the door jamb. Everything is tight and nothing lying at the bottom like it sounds like.

Will start again tomorrow.
Any ideas?
Randy
