My A6QW does not have the Tiptronic, but the regular 4-speed
automatic. This is *exactly* how I was told to drive it: stay
in 3rd around town, leave 4th for 50+MPH cruising.

I do it a lot, but don't have many miles on the car (4K so far).
I suspect the only problem will be a slight lowering of mileage.
I put 200+K miles on standards driven routinely at 3K+RPM, no
problems at all with the engines or trannies.

In a hopefully-unrelated question, I've noticed that when I leave
it in Drive, if I am "coasting" along with little power, when the
3rd-4th shift happens, the car sometimes selects neutral for between
1/2 second and 5 seconds. Then it drops into 4th with a slight
shudder (1/2 second) or a huge KER--THUNK!!!! (5 seconds) given
the high revs from being in neutral.

Anyone else with a slushbox seen this?
