Can't help on the gearchange but mine has always run noticeable
rougher at idle with the A/C on. Got the garage to look at it once,
thinking that perhaps there was something wrong with the AC
compressor, and thus putting too much resistance on the engine. But
everything was ok.

It was probably only noticeable by me though, not sure how much of a
vibration you are talking about!
