    Default 4L60 to 4L80 2002 Silverado 5.3 DBW 12212156

    I have silverado, with the trans swapped to 4l80, the wiring has an adapter harness, doing research and searching these posts,
    Question what is a segment swap? is it copying a section of binary information from one file to the other? how is it done?
    is there a bin file that i can reflash this LS1B pcm with to run the 4L80 DBW 5.3L and 4l80 as if it was stock?
    thanks in advance

    So you open your stock tune. Then do a comparison (CTRL + F11) of a OS with a 4L80.
    Then click Edit, Copy Entire Segment, Transmission Calibration.
    Then Click Edit, Copy Entire Segment, Transmission Diagnostic.

    If you need a 4l80 tune i can send you one. Or i can do a segment swap if you need that.

    Glad you have it figured out. What numbers were off when the speedometer was off?

    Just purchased a used Flashscan V2 and need help to finish my 2002 5.3 Silverado 4l60e to 4l80e swap. Using swap harness from Amazon that included 2wire pcm pigtail harness. Very new to tuning. Want to learn and share.

    I will attempt to pull the stock tune soon. Still working on the frame resto. Once the bed is back on then I will try to figure out what exactly the "Segment" is. Still so new to the terms as well. I appreciate your response too.
