I tend to down shift at either low speeds (say under 35mph) and I will roll to the red light anticipating that I won't have to stop. Or at high speeds (saying coming down an off ramp formt the interstate) I will drop to 4th then to 3rd to allow the engine to assist the brakes.
Otherwise I just drop in in N and use the brakes to slow.
Chattering when shifting is not a good thing, a solid shift should clunk at most.
