Few days ago, I started my ar and put into drive. The car seems like not really moving and in neutral mode. Hmmm, so I step on the gas and is engaged back. So I thought is fine. Yesterday I was driving on a main road... omg, the car all of the sudden won't go when I was on the left lane. I stepped on the gas, the car screams...and the car seems like in neutral mode, but it do moves a bit. So after like 40 seconds or so, I feel the tranny engaged back again and the rpm jumps back from 4500 rpm to 2000. Anyone knows what's wrong with my car? Do I need a new transmission? Anyone knows any good mechanics who do a good job on this pain in the ass bimmer tranny in NY area? Thanks everyone!
