I was wondering if it was possible to do? I have a 04 HD with a bad transfer case, was going to overhaul it in the spring. But several weeks ago, I had a transmission cooler line break and fried the transmission (my son was driving, I think he hit something to rip the line out of the radiator). I've now come across a used transmission with low miles, they also have the transfer case, but it's manual. so like I asked at the beginning, can it be converted.
