A6 transmission
I'm noticing that my A6 has a hesitation at low speeds. The dealer says yes you do, but it not bad enough for GM to pay for a fix. Is any body else having this problem? If yes what can we do about the problem? I understand all the newer 06's don't have this problem as GM has corrected the problem.

I know that there's a bulletin out about a slight hesitation/delay before the trans responds when shifting into drive (mine has a very mild case of this) but I haven't heard too much on a hesitation once in gear and driving.

I posted some notes on this previously. The dealer fix is to re-flash your computer after pulling the radio J fuse out (under the hood on the passenger side). You'll get much more driveability and a less loosey-goosey feel under part throttle/cruising conditions.

That is soooooo right.
