but I don't think that's what's causing the car's vibration when shifting into gear.
could be, actually. you mentioned a low idle rpm...a poorly running engine can idle low, and when you add the load of the torque converter when drive is engaged, it could pull the engine idle low enough to cause vibration as the car nears the point of stalling.
