I am converting my 2000 Camaro from a T56 to a 4L80E and looking for help on how to get it hooked up and tuned the best way. I have EFILive and I am using their Custom OS3 based on the 01/02 Camaro OS (12212156). I was planning on getting the Speartech T56 to 4L80E harness and then do a 4L80E segment swap but was reading if you did that then the converter would unlock anytime you left off the throttle. Supposedly you can control the 4L80E with the 4L60E calibration and not have to worry about the converter unlocking anytime you left off the throttle. To use the 4L60E calibration do I need to get an auto engine harness or do I still need to get the Speartech T56 to 4L80E harness? Any help would be greatly appreciated?

Thanks,
John

you should be able to use the adapter harness , but you may need to swap some of the pinouts at the pcm and add a relay to run a 4l60 tune.
