Is it just the torque converter lock up staying in??
If it stays in, it allows the engine to supply some braking effort, as it would in a manual car.

Turn your music off, and listen to the exhaust note.
When coasting down hill and the foot right off the gas pedal, listen to the exhaust.
Then apply the slightest amount of throttle - not enough to speed up, but just so there is weight on the gas pedal.
If the exhaust note goes quieter at that point, then the torque converter has come out of lock up, and no more engine braking.

Engine braking is good - saves on brake pads.

Not sure if the VX is supposed to do this, but mine does it all the time, and has done since I bought it second hand.

Circmand, I experience the same slowing down you are talking about. But I always assumed it was caused by what PK describes-- it feels more like engine braking due to the fact that as soon as I apply the slightest pressure to the gas pedal. Also, when going downhill, if I shift into neutral the engine braking effect goes away completely.

Also of note is that the VX seems to do more of this engine braking in "Power mode" than in normal mode.

I have been operating in power mode since reading it helps with gas mileage here. I think this started happening around the same time but I was dealing with a new PCV valve and changed the fuel pressure regulator so I did not make the connection. Thanks everybody.
