12225074 4l80 swap

[bummer]

Greetings to all!

Now I am working on the 1999 Silverado project with the LS1 engine from Chevy Lumina SS (Australia) + RWD 4L80E from 2003 6.0 Suburban.

The mechanical and electrical parts is finished, went to the PCM setup.

I read the forums and I realized that I just can not do segment swap 4L60 to 4L80.

Tell me how to solve the problem?

PCM 411
OS 12225074
1. Go from 12225074 to 12202080? What to do with the engine settings?
2. Manually overwrite the 4L80E settings?

Or are there other ways to solve the problem?
