Hi guys. This is my first LS swap and trying to do it all on my own. Eventually, I'll get a professional tune but for now, I just want to see if I can make the swap and get it running. I've started with a LQ4 out of a 2001 2500 2WD. I have the enginer rebuilt and the complete harness and PCM (411 12202088). I've got TunerPro and LSDroid and done enough research to delete VATs and turn off O2 errors. What I don't understand, is how to change the transmission. The original truck has a 4L80E and I have a 4L60E. It seems like there is a way for me to find an XDF from a vehicle that had a 4L60 and copy/paste (segment swap) into my original BIN. Is that right? Could I get some guidance on how to do that? I can't seem to find a walk through. Thanks
