rpm are around 19 or 20 thousand

are you running oversize tires? 1900 is a fairly low rpm and i noticed my own van has a shuddering vibration as the rpms drop and it is still in overdrive. it's caused by the gear ration being to high and the added strain of firing against this impossible load ratio turns up as vibration.
