Clutch Slipping? Normal SMG stuff?

Okay so I am just a little concerned. I was on my way home from work and playing around a little bit and noticed something odd. I was in s4, traction control off and sport pushed. I didn't even have it wide open but getting on it. When shifting it (not at redline) it seemed like from 2-3 and/or 3-4 it felt a little shudder and then engagement. Not sure if it is because of being in s4 or what. Any advice?

Reset your SMG by using the paddles. Have you done this before? Everyone once in awhile the system gets a little confused.

How do I do this re-setting that you are mentioning? Sounds like would be a good idea since I got the car only like 3k miles ago and no telling how the last owner drove but based on the music left on the phatnoise harddrive probably very slow

Drive the car at +30 MPH (+50 KPH) and put it in N and then pull both paddles for ten seconds. You'll feel the car adapting to your shift points.

I reset mine a few days ago and while the difference isn’t night and day; it is noticeably smoother on the up shifts. Definitely worthwhile to do this every so often.

Mine was shuddering as well and then it progressively got worse. I would try resetting the smg first and if that doesn't work then have a indy shop check it out real quick. It also could be TPS sensor, etc but you won't really know until you get it diagnosed...
