vibration shifting to O.D.
 

i have 2003 ram 3500, cummins 5.9, auto trans. quad cab 4x4.
I am getting a vibration, growling type noise when tranny shifts into OD. So far i have replaces torque conv., re-built tranny, new turbo and inlet pipe. Dealer cannot figure it out. Vibration feels like its coming from tranny hump in cab. HELP!!!!
