Hello everyone, I have a 2008 and 2009 Avalanche LTs. (I know it’s not a Silverado but I really need some help here) my main issue is my 2008 has a built 5.3 and a built 4l60e. My 2009 is rust free and I’m currently installing my 9 inch lift on it. The only issue is the 6 speed transmission is junk, it has no gears besides park. Is it possible to swap the 2008 motor and 4L60e into my 2009? I’m hoping it’s going to be as simple as a normal motor swap but I’m not sure what all it entails. I’m sure the cluster is different but besides that can I just transfer my ECM and tcm over? Or will I need to do some programming to my bcm and such. Thank you in advance!
