Dealer says "grinding into second is not abnormal"

I have a similar issue when shifting from 1st to 2nd. I've had the dealer look at it and was told it is normal as well. My issue isn't a grinding sound though. When I shift from 1st to 2nd at low speeds, especially in the parking lot at school or somewhere like walmart where somebody is usually walking by, the engine or transmission shudders like it would if the engine were to die even though I'm still going??? It's like when you're first learning how to drive stick and kill it a few times in first, at least I did way back when, but in this case the car doesn't actually die. In another reply, I read where the clutch may not be fully disengaging and maybe that's what's happening with my car.
