Auto trans rolls forward in neutral...

Hi folks, just noticed that my 320i auto rolls forward a bit when in neutral and also seems very sluggish up to 40mph. Any ideas?

I don't know too much....but i know that its normal for automatics to roll forward or backward depending on the slant of the road..

As for the 40 mph thing....i'm not to sure, hmmm i would say do a tune up...get the spark plugs firing at the right time....BUT the best thing of all is see a technian.
