Not sure but guess what...truck is still in the shop. They were "done" two weeks ago, so they told me to drive it around for a week then bring it back in after a week so they can make sure there are no leaks and whatnot.
I test drove it and realized that the shifter is kind of loose, the truck still sometimes bucks a little when changing gears ans the brakes are still so bad - the whole truck rattles when I brake at anything above 30mph. Brought it back in over a week ago and now they've replaced the brakes, cut the rotors, ordered a new cable for the shifter as they told me that the cable in there was bad, have to replace another cam phaser as one they put in is "faulty", the stereo they said is having issues so are replacing the head unit. It just doesn't end it's crazy. A truck that I purchased on;y a few months back...sucks...
