Starting the swap. decided to go with the 5.3 harness and got my pcm programed by NP. installed a hd2 shift kit in the trans a few days ago. The trans looks brand new on the inside. It doesnt even look like it has any miles on it. There is a GM goodwrench sticker on the outside of it so maybe it was replaced within the 60,000 miles the truck was alive! I rebuilt the rear end last night and installed a posi. going to install a 30spline input shaft on the transfer case and replace all bearings and seals while im in there. Im also installing the turbo during the motor and trans swap. messing with alot of stuff at once. I know im raising the chance of something going wrong but I have to get it all done by next week. I'm taking the truck down to NP to have them button up the tune in a week. hopefully I can get everything done in time!
