Is this normal for the tranny?

I have on 07' H2 and notice that sometimes you feel a vibration as if the driveshaft is not balanced correctly....It's a small vibration like the exhaust may be touching the cage, but only does it if you are stepping on the gas, and right before it will kick down to third.
I also owned a 05' H2 a while back and that had the same vibration........which got noticeably worse when my ignition switch failed......just curious as to if all H2's do that.....?
