Shuddering feeling while shifting up to 35mph
 

**Technical question**
I have a 2014 RAM 1500 5.7L V8 Multi Displacement VVT.
I've noticed that sometimes when shifting up to 35MPH, there is a shuddering (for lack of a better word) that seems to be happening. The vehicle shakes/shudders a little. This can happen while towing or without a tow load. It seems to be somewhat random.
Does anyone know what might be causing this or if this is normal behavior? When above 35-40 mph and shifting it's very smooth and I don't notice any of this "shuddering" whatsoever.
Thanks!
