Changing Gears
I've noticed when I'm leaving out of the neighborhood while driving real slow and the transmission change gears I feel a stomp like it kicked into gear, is this normal, at normal speed it's fine. 2007 auto 80000 miles.

The A6 is somewhat sensitive to temperatures below 140-150, especially at WOT. The shift points aren't consistently at the same RPM. At least that's what several owners, including myself, have experienced.

Yea, HOXXOH is right. Many, but not all, A6's get a little "harsh" when cold. I wouldn't worry about it unless there are other odd behaviors that concern you.

The OM recommends 50K for severe service and 100K for normal service. They identify severe as hot city traffic and/or hilly. Assuming most of your driving is local in Texas, my opinion would be it's probably a good time right about now. If you do it yourself, there is a very specific procedure to be followed. If you take it to someone else and they are not 100% familiar with it, don't let them touch it. Unless you totally trust your dealer, find a Vette specific shop. I would avoid any place that wants to do a flush, since the filter doesn't get changed. The change will take about 7 quarts of fluid. It must be Dexron VI. I always use Delco, since that's the fluid GM used for all their engineering and testing.
There have been several threads about changing the fluid, but sometimes there is incomplete or erroneous information, so I suggest you get a printout from the service manual. That way you'll be assured of knowing how it's to be done and you can confirm that someone isn't BSing you.

OP my 07 shifts the same way. Under very light throttle, or even more so when letting up on the throttle right before it shifts....bang a hard shift.

That applied mainly to Fords I believe. The fluid would varnish and stick to the internals. When new fluid was put in it dislodged this varnish and plugged up the passage ways.

Right, did you fix it or still dealing with it.

Ford used no friction modifier in the early years. Most others used whale oil, which worked well until it was banned. The older trannys didn't like the replacement fluids, so many people chose to never change it. I personally had a '70 El Camino with OEM fluid when I sold it with 236K miles.
