If the vibration is new, or worse since the service was performed, than the t-belt is likely off by one tooth, probabally the rear exhaust cam. If it is the same-in fact if it has always been there, it is possibally normal. It usually gets a little worse when in drive, at idle, because the idle speed is a bit lower (despite load compensator) but mostly because of the load placed on the engine by the tourque converter.
PM me if you think it is abnormal or a new problem, and we can share some of my experience on the matter.
