The car wont shift out of park when car is running. But if you shut the car off it will shift out and start in netural but wont shift into any gear.
this is by no means a cure, but for the time being you can get it into gear with a bit of patience ....and timing. as your turning your engine over..at the point it turns over put it into gear-it might take a few attempts but you should get a gear. i have had a couple of beemers that i have dismantled do this(both e36 compacts) . remember keep your foot on the brake. once its started it may remedy itself. timing is crucial with this trick. :-) just before your engine fires it will slide into gear.
my trans am had that problem, it was a transmission mount. Not sure about a bmw, it could be a lot of number of things.
