Mine will vary from completely seamless to feeling like the truck is shifting down (still pretty smooth), just depends on the load required. I have also noticed the amount of time in V4 changes with the weather. Got up in the 50's for a day last week, and the truck spent alot more time in V4 than it does in single digit temps. Brought my average mpg up nearly two miles that day.

1300 miles here. City driving with mix of surface streets and highway. City is pretty hilly, but I'm pretty gentle on the gas. Been averaging 15-16mpg. A little dissapionting considering my last truck was getting about 17-18 city.
