Yes, I agree completely that I have the worst version for mpg. AWD 5.3 and 3.73 gears. None of which are helping me out.

I wanted the 5.3 as they make more power and the difference in mpg is not that large at all. The part that really kills it, is the AWD.

I also am keeping 40 to 45 in the tires as well. We have the same size wheels and most likely the same tires as well. 275/55/20

Transmission cooler is in the center, right behind the Chevy emblem. On the drivers side is the powersteering cooler. I have both. I use the Torque App to both monitor all of my temps and to tune my driving. That's why I removed my 75% grill block as the trans temps were becoming to high for my liking on a day to day no load highway driving(175-185°)

The slots in the bumper have a black plastic fillers. There is no airflow through them for mine. The only airflow I would be getting would be through the lower opening. I don't think I will be blocking from the front due to appearances(I really like how it looks lol)


It turns out my ECU does to DFCO. I just haven't been watching at the right times yet. I noticed it the other day. I would like to get the tuner to have it enter DFCO sooner and hold it longer.
