I am fairly new to the LS platform. I have a 2013 sierra with a 4.8 and 4l60. I picked up an l96 for it. I want to swap out the 4l60 for a 4l80. What year 4l80 is compatible and what all do I need to make it work? I?m sure this has been asked a thousand times, but I keep getting contradicting answers everywhere I look.
