    In search of 2016 Jeep SRT8 Stock File

    Hello,

    I have a 2016 Jeep Grand Cherokee SRT8 6.4L here that was being messed with by another tuner and has some interesting shift habits going on. I would like a stock transmission file to start fresh with, but the owner states he no longer has it. If anyone has a factory file with the following OS I would highly appreciate you sharing it with me .

    Engine:
    GPEC2A, ECM, 2015+ Dodge
    OS: 68277171AG


    Trans:
    Hardware ZF8HP, TCM, Dodge
    OS: 05035476AF


    Thank you.SRT8 OS ss.PNG

    dodge installed the 8 speed trans in multiple platforms

    ZF supplied dodge with over 100 different OS

    not sure what ZF was doing back then or why it went down like that but it did

    the good news is there were not hundreds of different calibrations, just lots of revisions to the OS

    i do not have a 0503 5476 here
