My 08 sprinter 3.0 V6 has a vibration that will almost shake the dash out of the cab , When cold it dose not do it , You have to drive about 30 minutes and then any time you load the engine it vibrates , The TC was replaced , The drive line has been inspected , It almost feels like and engine mis , It dose not do it when revving at idle and dose not do it power braking the engine , No DTCs in ECU or TCM , When the vibration starts about 55 MPH while accelerating or loading the motor the power is diminished , Shift to neutral and vibration goes away , Some times if you shut the engine off it will take a few minutes before it starts vibrating again , If you let it set over night you have to drive about thirty minutes , Checked the fan clutch , Pulleys , Belts , AC , It dose feel quite like a TC shudder however , Much harsher and we did put a factory converter in already

make sure the torque converter is bolted tight to the drive plate , the gearbox is bolted tight to the motor , your mounting are not torn & oil soaked . Oily rubber mounts can become soft once heat is added to the equation .

Check your rear trans mount too.
