Carr04Avant

My 04 S4 Avant has been having some trouble with the transmission lately and I'm not sure if it's anything to worry about. When rolling to a stop, the tranny shifts through 2nd gear and produces a slight jerk or clunk before hitting first gear. It doesn't do it in Sport mode though. I've researched all over the place to see if someone has had similar issues. I just had my ATF changed, and I've contacted multiple Audi dealerships to see if there are any tranny control module software updates. Another downside is that I'm trying to sell the car and this will obviously only scare people off. Any feedback would be appreciated.
