Yes, it's the "generation 8", made from '95 to '99, and I believe they're around 4000 lbs. and have a Cd of .31 or so. I suppose that is a good combination for extra-long coasts.

And I think Old Mechanic is right about the torque converter completely "un-locking" during a power-off coast, too .... I have shifted between "neutral" and "drive" while coasting without being able to detect any difference at all.
