OK, It did it for me this afternoon! It isn't the diff. It is definetly coming from the transmission area. I started the car and it was whining when in park. When shifted to either R from P or N or from R to either P or N it made a metallic clunk, not quite grinding. When in either P or N it made a whinning sound. When I shut it down the whining sound dropped off like something free-wheeling(the torque converter?) to a stop. It was low on ATF just like when it happened for my wife.

Anyone have any suggestions? Thanks ahead of time!
