I had a 300d turbo engine installed in my 240d with 4spd man trans. I have a driveline vibration at certain rpms/load. One mechanic told me that there is a special flywheel that needs to be used for this swap. The shop that did the swap told me that wasn't true, everything will work just fine. Any help?
