    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.
