My sliptronic was replaced two days ago and I swear it feels like a totally different car. It is definitely faster and more responsive. I can now actually feel the difference in the sport drive mode, whereas before I could not. The rpms hold up longer. The original transmission I had was definitely defective in more ways than one. The cold start/reverse problem was only the tip of the iceberg IMHO. It feels like a brand new car now. Much, much quicker. Go figure...
