4l60e Pinout
4l60e Pinout to the pcm. I did a LS swap on an 89 K5 blazer, but I originally kept the 700r4 to go behind it. I recently sold it and put a built 4l60e from a 2006 silverado behind it. I had a stock transmission harness, to pin in the computer since my wiring harness was built for the 700r4. I've seen a couple different wiring diagrams for this transmission. I have 2nd and 3rd gear, that is all. When I put it in drive, it starts in 3rd but I can manually shift from 2nd and 3rd. Any help would be greatly appreciated
