    2005 GMC Yukon XL 4L80E swap

    If someone could help verify this segment swap file i did, i pulled it from a stock 4L80E 05 Silverado 6.0 2500HD 12592618OS in the repository but i want to be sure its good before loading it into my truck.

    Would be loading it into a 2005 GMC Yukon XL 1500 5.3 OS 12592618 with a 4L80E swapped.

    if needed for reference i used this harness, https://www.ebay.com/itm/164777370889, not one like the PCM of NC harness that only uses one VSS.

    Update, tried a tune that was taking the values from a 2000 Sierra and that didn't work. Was able to get me home but I had to use the command gear controls in VCM scanner. Writing the above tune now to see if it will work on its own.
