A segment swap is no longer required as long as you have a 4L60 capable PCM.
I just got finished with my road test. I have a 2000 PCM running a 4L80. I did have a segment swap done, but was tired of the TCC unlocking below 5% throttle (no matter what).
Edit: I had a change of heart. I have a good bit of time in this. PM for details.
Oh BTW my converter no longer unlocks below 5% throttle.....
Also note, you will still need to move 2 pins on the Transmission (see below).
