I read that you need to swap the output shaft and housing in order to run a 4wd 4l80 as a 2wd. Can anyone confirm this? Would I be better off trying to trade the 4wd for a 2wd trans instead of having it torn down and swapped? Is there anything else I should know before I try to do this? I'm taking a 6.0 with a 4l80 out of a 06 2500 to put in my c10.
