Hey all. cannot seem to find any info on this, sorry if has been addressed before. I am swapping a 2004 silverado 5.3 into my 72 nova. i'm usin g a pcm that was programmed for my 2004 4wd silverado. i will be putting a 2wd 4l60e in my nova. is there anything in the calibration i will need to change to run the 2wd in the 4wd computer? or should it all work just the same. Thanks in advance.
