Loud reverse rumble and cruising shutter

So ever since i took my car in to get my misbalanced clutches replaced, my car has been making a pretty noticeable noise when i shift into reverse when its cold out. Its like a grind or something hard vibrating around in my engine bay area. Its really weird but only happens when the temperature is cold outside. It does not happen if i am idling, but the moment i shift into reverse it makes the noise. It also not make the noise if i go straight into drive.

Also when i am cruising at about 35 mph, i can see my rpms fluctuation about 300-500 rpms randomly while at the same time making the same grinding/rattling noise. The noise also occurs if i cruse into a turn leading to a hill and give it some gas.
The noise, for whatever reason, make me think of a clutch puck that has come loose and is just like vibrating like crazy and wacking the clutch assembly as it rotates.
Im gonna take it in at some point but i have been way to busy to recently. Just wanted to see if anyone else is having these issues.

Il try and take a video some time so you guys can hear what i sounds like.

Question: Do you get the noise in R with your foot solidly on the brake?

35 MPH is the transition point between 5th and 6th if you are cruising (light throttle).
In other words <35 MPH = 5th and >35 MPH = 6th.

In that case, it is better not to stay at 35 MPH or you can shift to 'S' (which will keep it in 5th).

yes my foot is solidly on the break. It never made the noise with my old clutches.

well thats the thing, its in 6th gear and not shifting. The rpms drop for a second, the noise occurs, then the rpms go back up. As with reverse, the rpm drop and noise never happened with my old clutch. its between 35-40 where is happens the most. But i can defiantly see where that speed could be causing some clutch action to occur. I wonder if its only one of the clutch packs thats causing the issue. my guess would be the 2-4-6 clutch pack, especially if reverse is initiated on that pack. I dont know how DCT does reverse work that well.

Driving down Colorado St will do that... GO COUGS!

I had a bad thunking in my clutch on my 06 in reverse, but you have a totally different clutch. I'd check the slave cylinder though, that was my problem.
