    hyderm87, welcome to the forum...

    Some info:
    If you could copy all your tables to a 12212156 file, it would be easier to do (and you could use COS5).

    Basically you just need to find a vehicle that has a 4l80 in it, with the same os as yours, and copy the trans segment and paste it into yours.

    You can change OS by doing a full flash (after copying all the tables over).
    FlashScan V2 can do this.
    FlashScan V1 Commercial can do this... if you have V1 and it's not Commercial, then it's a $50 upgrade.

    You may not easily find any files containing 12202088/4L80E.

    It is easier to find files containing 12212156/4L80E.

    Follow the links in post #2.
