I would say it is the DCT. However, what is unknown is exactly what is causing the shuddering. The transmission seals are known to have issues and can allow oil to leak from the wet to the dry part of the transmission which contaminates the clutch and causes slipping. However, this is not the only issue with the DCT. For some reason, the shifting can get out of whack due to something that goes wrong with the adaptive learning process. If there doesn't appear to be any oil leaking into your bell housing area, it is more likely this type of issue. To remedy this, you can go through a clutch relearning process which can either be done at the dealer ($$) or using a cheap scan tool and the Forscan software. I'm actually due to do this again myself.
