    Greetings

    Hi Everyone,

    I'm doing an LS swap on a G Body cutlass that I've been working on and off on for 15 years. Yea I know that's a long time. I got 4.8 ls motor and 4l60e from a 2007 Sierra. I have the original harness, computer, pedal, dbw, etc. Looking for a stock xdf Any suggestions?

    Perhaps 2007 was the last year the 1 meg PCM (blue / green connectors) was used?

    Perhaps converting to an older 1 meg PCM that has a .xdf is an option?

    Perhaps the computer you have is the E38 ECM that is using the T42 TCM for the 4L60E?
