I recently purchased my first BMW. It is a 1992 325i and other than the automatic transmission, I am excited. I put 4 new tires on it and changed the oil using Mobil 1. I was wondering what the RPMs should be at when cruising at 60-65 MPH. My car is at about 2500-2700 RPM and it feels like it should be shifting. Is this normal for BMW transmissions? Thanks!
