Sounds a lot like stock just louder. To fix the shifting issue if you're still on the stock tune I highly recommend a OTT tune. Had it done on my 18 this past Tuesday and I'm blown away by it. Befor and after comparison the truck feels like it's had a bigger engine swapped in. Drove over 200 miles on the highway coming back from getting it done and at 70 it can actually pick up speed without downshifting and can maintain its speed up an incline without changing gears

Thanks, it needs something for sure! Get it done at a 4x4 shop?
