That has had a COS applied to it. You would have to have the original OS file to segment swat a 4L80 segment into it. There are 4L80 segments available for the original OS.

So upon talking with the customer he purchesed the vehicle modified and has no info on who tuned it in the first place so if i cant get the stock file what do i do at that point ?

One option would be to reprogram the module to stock with TDS outside of HPT. Not saying this is the only option though.

Custom Operating System. With such little knowledge about tuning you should probably just get the adapter that lets you run a 4L80 with 4L60 segments.
