Shudder under 2000 rpm seems to come from engine side of vehicle(passenger). This problem seems to arrise when van is in final geer and seems to smooth out quite a bit when you put it under a load. Could be vibration damper but it didnt start until pontiac replaced tranny lines.This van has all new suspension,struts,inner and outer tye rods, ball joints,Brake hoses and lines. and axles, brakes Lines,components even master. new tires,radiator and heater core.I am certified in steering and brakes but still confused. Any recomendations would be helpful. Thanks.......keith
