I am starting to put an '08 LS-3 into my '38 Chev. I have a 4L60E out of a 2004 Silverado. I intend to have the corvette harness stripped out and understand that I need a T42 ECM to link the transmission. Is a Delphi P/N 12586242 the same as a T42? I can't find anyone who knows what a T42 is.
I would appreciate any help, thanks.
