I've come to the site and it has been very helpful in my decision to perform an ls swap in my 72 c10 Yes I know it's not a Camaro but I am having problems finding a 2003 4l60e to match my 03 lm7 out of an Chevy Express full wire harness and ecu.....i have a 99 4l60e from from a 2wd truck with 5.3 what would I need to do to make this transmission work with my setup? I have searched several different places and they all have varying opinions on wether or not it's the same or different thanks, any help is greatly appreciated!

 

Your 1999 5.3 trans is fine behind the 2003 LM7,just use the PN switch that matches your harness.

 

Thanks Just trying to make sure the pcm can control it with no shifting issues
