Need some advice. Have a 99 NBS Short bed Z71. I finally found a D60 and bought it. I have the auto crap transfer case and the 4L60E is needing replaced. What if I got a 4L80E w/the transfer case from a NBS 2500 or 3500 and just swapped them out. Could I leave it push button or do I have to run the stick? Which transfer case comes in these trucks? Also, does anyone know what years the 2500/3500 trucks still had rear disks or if they ever had them. I know my 10 bolt has disk brakes but the newer 1500's don't. Thanks
