    Default 2015 Silverado L83/6l80 2wd file needed

    I am trying to locate a 2015 l83/6l80 2wd file for OS 12664769, I am working on a swap vehicle with a full 4wd pullout where the 6l80 was converted from 4wd to 2wd and now that the transfer case has been deleted, We are getting a P279B DTC. The table to change from 4wd to 2wd and/or VSS type is not defined in this OS, So I am thinking the only way around it would be to switch to a 2wd base file.

    Thanks!

    Ive got several 2015 tunes ive read off over the years. Is there a way to see if its 2wd or 4wd in the tune?

    I haven't been able to determine what indicates 2wd from 4wd in any of the files that I have found floating around, I did find a 2015 Tahoe L83/6l80 file that the owner indicated was 2wd. Same OS number 12664769. I am going to copy over all of my calibration settings and give this one a try sometime this week when I have time.

    I believe the 5th digit of the VIN tells you - K for 4x4 or C for 2x4. If I'm not mistaken.

    I've had major issues with getting signed into the forum and my hotmail has been sending everything to junk, But wanted to circle back around to this and update that I tried flashing in a 2015 2wd Tahoe file and so far the VSS is reading correctly.
