First, take your foot off the pedal. THEN:

Don't do that. Why would you do that. Don't do that. It doesn't save
any gas or brake linings. It's not easier on the transmission. Don't
do that.

Normal. Not just the Taurus. GM even has a problem w/
transmissions(4L60E) because of this behaviour.

I discovered this by trying to isolate a vibration problem at high
speeds...And my foot is not on the gas.....for some reason when the vehicle
is doing 75mph the computer is telling it to keep the rpms up....this
doesn't seem normal to me...

It's normal. I won't explain the details, but it has to do with the PCM operating
strategy. The PCM doesn't expect to see ~60-80 MPH with the trans in neutral. It keeps
the RPM way up to lessen the chance of damage if the transmission is re-engaged at
that speed. Basically, Don't Do That!!! The PCM can only provide SO much protection
from stupid abuse like that. If that was a 70s car, either the trans would come apart
when re-engaged or the engine would overspeed. Why in hell would you put the trans in
neutral at 75mph and then re-engage it??
If you are doing stupid stuff like this to find a vibration, you really need to take
the vehicle to someone who knows what they are doing before you cost yourself a bunch
of money.

Tom..

To me this seems like a dumb design because the car seems to not slow down
as all my other cars have when you take your foot off the gas when the car
is in drive....to me it seems like I always have to have my foot on the
brake to slow the thing down.

Thanks for your imput...Even though you seem to be making me out to be a
moron...(grin)

The 2000 Taurus is a very slippery free-rolling vehicle - by design, for
fuel economy purposes. Believe me, when it doesn't need fuel, it shuts
off as much as possible.

Not intending to make you out to be a moron. Just don't do that and send me the $2K.
I've got a daughter starting college in the Fall
Seriously, going into neutral and back into drive can damage the transmission. It's
just not a good idea. Like Rob said, that car rolls very easily and loses speed slowly
when you take your foot off of the gas. I noticed that right away going from a pickup
to a 98 Taurus. It's nothing to worry about.
