First off, I had a my TC replaced about 2k miles ago, and payed $700 out of pocket to have my trans flushed and filled as it was not an included operation and I wasn't comfortable driving the car home with the old fluid in there after a TC failure. That was at 62k for the record. Since then my trans has progressively gone down hill, but with different symptoms than most RS6's display when the trans has failed. It wants to shift at 1400 rpms, and maintain about 1200 rpm's at all times. It hits 3rd gear at about 20mph, 4th at 30mph, and 5th at about 40. If I use the paddle to try to downshift back down a gear it will inevitably just shift right back up. All the while it seems to be slipping. If I get angry and try to mash the throttle to try and coax a downshift, I just get a long delay, then it sits in limbo and tries to downshift only to up shift back to the wrong gear, leaving me at 1200rpm. Oddly enough, sport mode seems to still hold shifts to a higher rpm, but only if I start out in S mode, If I click it into S while driving, I no longer get that immediate downshift that I'm used to. My first thought was that the trans was under filled, but the dealership was confident that this was not the issue. I have an appointment for Wednesday morning, but am just trying to get a better idea of the cause of this or the possible outcome before I get their response. I'm thinking perhaps a clogged up valve body, who knows. I'm just afraid they are going to find a simple electrical problem without giving any thought to the damage done to the trans while being driven like this. I'm praying that it needs a whole replacement gearbox.
