I guess my 4x4 might not be working to well, pretty much I was trying to get out of my driveway, due to a lil bit of snow I put it in 4 high. At first it wasn't switching into 4wd right away for some unknown reason. So after driving it in a snowy parking lot in my house with it still in 4wd it kicked in after driving it forward. I have push button where you have to press the buttons for it to get into 4wd so I was wondering, is it normal for my truck to shift into 4wd when it drives forward? I was also backing out of my driveway when this happen, not sure if it matters but my truck is lifted a little bit(not sure how much got the truck with the lift kit)
