Looking to remove the 2005 4.8 with 4L60 and replace with 2007 6.0 with 4L80
Can I use the same PCM and wiring?

Just a little help but not much...you will want to make sure your reluctor wheel is the same if not you can buy a kit to read from a different reluctor wheel to the computer. As for the transmission, your wiring will be a little different. Those two things are really the only things I can think of and then obviously you will want to have the computer tuned to compliment the swap.

Here is a link for the trans
