The only thing I can come up, mine does it too, is that there is more, for lack of a better word, force in the system in the lower gear and the bang is to do with disconnecting that. It seems to do it more when coasting to a stop uphill in my case.

My car does that also and it is usually at low speed with the throttle off.

Your explanation seems reasonable.

hmmmmm That would lead me to believe that there is too much "slack" or "windup" somewhere - eg, engine/trans mounts. Might be fixable. YMMV

Sounds reasonable except the only feedback is through the clutch pedal, can't feel it with the other foot on the floor or in the seat. As for the bang and rattles, I'm almost certain the rattle is flywheel chatter so the bang could be just an extra loud "chatter". I've only had the car a month and it only has 5xk, bought it used, on it so I'm still feeling it out and learning it. Just trying to make an educated guess.
