Wife complained that VW was almost stalling out when coming to a stop and
also when moving from a stop. I happened to be in the car with her when it
happened again and it can best be explained as if it were a manual when
first learning to drive. It's like coming to a stop and suddenly realizing
that its a manual and you need to put the clutch in to keep it from
stalling out, in other words I think the trans is staying in gear and not
shifting to neutral properly. The tach drops from around 900 to 3 or 4
hundred then its like it goes up to normal after almost stalling out.

It sounds like the car's torque converter might not be releasing soon
enough.

The car died completely coming to a stop about 3 months ago and the dealer
put in a fuel relay and reset the throttle body. When I took it in this
week they reset the adaptive trans by turning on the ign and holding the
gas pedal to the floor for 5 secs then turning off ign and restarting.

I'm not sure about all VWs but on Eurovans (also adaptive transmission) the
procedure is similar but a little different so I wonder if the dealer got it
right.

This is the procedure I know of (I have a Eurovan):

1. Turn ignition on.
2. Turn ignition off.
3. Turn ignition on again, floor gas pedal for at least 5 seconds.
4. Release pedal and start the car. Done.

Maybe try that? Heck...it's free and costs only a few seconds of your time.

Car has 40,000 miles on it and has VW certified used car warranty. Is this
a problem to be concerned about? How long does adaptive trans take to
relearn. What is an adaptive automatic.

The adaptive automatic basically just "learns" your driving style and when
reset it reverts to factory default shift points. After reset it should be
smooth...it should just be shifting at the factory-default revs, etc.
between gears.

I've never felt this kind of hard downshift in any automatic I've owned
before. What next steps do I take since its under factory warranty? Dealer
did a complete 40K service at 38,900 when I had last oil change. We've had
car since about 34,600 with no prior trans shifting problem at all its been
smooth as silk.

I would say that you might want to try the procedure above first (try to
reset it one more time). Then, if that doesn't work, it needs to go back.
You might have a dirty valve body. VW will like to tell you that its autos
are sealed for at least 100K miles but that isn't always the best advice.
Dirty ATF fluid or low ATF fluid can cause poor shifting. They should check
the level and condition of the fluid and change it if necessary as well as
any filters in the transmission and clean the valve body. if the ATF is
low, you have a leak somewhere and that should be covered by warranty.

If that doesn't work, it could be a defective torque converter that isn't
releasing properly. That's more complicated.
