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

what do you mean? the os number you gave me matches for a 2002 os how would i swap to a different base os??? Thanks

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.

yeah that is the problem im having is finding a os like mine with a 80 in it. so far no luck!!!!!

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.
