That is going to be a tough one. Most of the HD trucks that have the new style pcm have a 6L80e, I may be wrong, but most of them are. I'm not sure GM made an 80e with the E pcm.

Very nice write up .
Is it hard to do a trans segment swap in the tune ?

Not if you have two operation systems that have the same version.

I'm not programmer, just a tuner, but I do know you have to have the right tools. I'm pretty sure you can't pull an 80e segment from an older pcm and put it in a newer e40 vcm.
