4l80e swap into 1260691 pcm

[Dylpicle8]

I have a 2005 Silverado Z71 4x4 with push button (autotrac) transfer case that I am swapping a 4l80e into. The O.S is 12606961 and I can't find a 4l80e segment swap to match the OS. Any help with this is very much appreciated, thanks for any answers.

Might be hard to find unless someone has one...

Seems to be that way, can it be flashed as a new operating system that is compatable? I have only ever seen one file which claims to have the segment in the right OS, but it is for HP tuners and I don't have the software to even check it. :(

Check your vin on GM tis and see if there is a newer OS. If I have the vin I can pull the latest calibration

Sorry for not posting initially, the vin is 1GCEK19B55Z298476

Well 12606961 is a newer OS the 12592618 was an older more common OS that I have a bunch of 4l80 files

Are they compatable/flash-able into my truck? Really appreciating this help!

Google GM tis and punch your vin in to get all the Calibration data
