    OS12606961 is an update of 2005 truck OS12592618. Most trucks that received this OS update were 5.3 L / 4L60 models. The 2500 series trucks and Express / Savana vans (models with 4L80s) seemed to continue to use OS12592618.

    I don't have a tune with that OS for a 4L80, and I have actually yet to see one.
