Major Breakdown, big cluck, engine whined up and nothing.

[bdessinger]

So, looking for some advice/help. Had transmission rebuilt at 90k miles on my 2003 x5 4.4. I currently have 115k Miles on it. I hit the gas at a stop light and went about 50 feet and hear a big cluck engine winds up a few not so pretty noises later no power i tried to put in park and Nothing. Had to put parking Break on to keep car from rolling. The noise i heard was like metal on metal not grinding but rubbing. Any ideas of what it could be before the shop looks at it. Just trying to decide what else can go wrong I have about 7k in the car in the last 2 years. Wonder if I should keep it or get rid of it. Problem is I love my car. UGH. Any help would be appreciated.
