2012 LS3 into '55 Chevy swap questions Looking for some quick answers, trying to help a friend out.
He's got a LS3 pull out, ecm, and harness from a '12 Corvette that was an auto (6l80). He's got a 2004 4l80e for his swap. Is there some way to make this work with the stock ECM from the Vette, or is a stand alone tcm controller hos only option? If more details are needed I'm sure I can get them.

Contact WWW.SPEARTECH.COM and see if they slowed down enough to start offering harness reworking. If not and the budget allows it, they can build you a new harness for what ever tranns you want. IIRC, with my order the TCM was ~ $125-1$150 with the ECM reflash. John and his crew have great customer service after the sale too.
A lot of people go strickly lowest price and run into problems with sub-par customer support.
