I am currently working on an LS3 conversion - going into a Jeep rockcrawler. It will be backed with a 4l60E. I am looking for the most simple ECM/TCM/Harness to control this beast. Are my only options a E38 and T42? How about an older 58x 2 meg PCM?
If I went with a E38/T42, do I have to run an input speed sensor on the 4l60E?
What do you guys think?
Thanks,
David
