I read that DC is going back to the getrag transmission, my first gen truck had almost 300k and never had problem w/transmission. Other than the 5th gear on my 2nd gen I was wondering why they are going away from the nv4500 and 5600. I also heard they are boosting power and more importantly making a full crew cab, can anyone confirm this? I don't need the 4500 rumored to be on the way, but the full or maxi cab as their supposed to call it would be great. Thanks Bill
