Ron: I have same car, same year. Had the same problem and after having the mechanic chechked in, found old seals stick to strainner in the transmission, changed filter and fluid and back to normal again. Could be same problem. Check archive under "transmission problems" Good luck. 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? Thanks everyone! Ron
