TBH I thought the trans was disengaging or something while the brakes were applied at lights and that was what happening was it reengaging or 'waking up' or something of the sort.

at least, that's what it felt like.

as for accelerating, I don't recall it for sure but I do seem to believe there was also a bit of delay to the car accelerating. It wasn't instant response that's for sure.
