    99 Sierra 5.3/4l60 XDF or update to 2156?

    Have a 99 Sierra 5.3/60e that has the 3372 operating system on it and have not been able to find an XDF for that OS, does anyone have one? Failing that, what do I need to do to be able to update the OS to one of the 2156 5.3/60e OS's?

    To update you just have to flash a compatible bin that matches your vehicle. Mostly transmission segment, and engine size.
    Have you tried universal patcher? It should be able to read your bin. And generate an XDF.
    No need to re-invent the wheel. But we can make it better
