Trying to 4l80e segment swap my 99 GMC 1500 with 4l60e. From what I've read I need a tune file with the same OS as my truck in order for the segment swap to work (it's greyed out). I have been unable to find a factory 4l80e tune file with a 1273008 OS. Help please and thank you.

Do you have the stock file you can post?
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Here's my stock file:
May I ask where you were getting the OS number 1273008 from?
This files stock OS number is 9373372. You'd just need an OS that matches that number to perform the segment swap. Find a 1999 chevy/gmc 2500 file and it should be all you need.

Sorry, posted the wrong OS number. Do you know where I can find a 4l80e tune with a 9373372 OS? I've pulled several from the tune repository and hav't found one yet. Thanks for your time! Mike
Sometimes it's easier to plug that OS number into the search bar too.

Thank you! Worked like a champ. Now I can get my swap going. I really appreciate the help. Mike
I am looking to do a 6.0 with a 4l60e how would I go about changing the ecu?
