"Segment Swap| in my PCM.......4L60E to 4L80E transmission swap.....????
What is this process? Is it simple and fast?
I am installing my new 4L80E and I am also upgrading to an (99+) 0411 Dual Tune PCM.
Also....can my current tune in my factory 1998 PCM be pulled out (it is NOT locked) and simply downloaded into my new 0411 PCM....?
Thanks.

Man, it never ends with bad news.
Why can't I install my 4L80E and have it work with my 1998 PCM and current tune?

Yes that can be done to a certain extent. There are slight differences in the tables between the two PCM types and OS used in each one. There are multiple OS you can run in a 0411 too. Also there are ways to run a 80 on a 60 segment. I've never done it but here is a thread describing how to do it.

I guess the tuner can look at my 1998 PCM tune and start from there and then during the dyno tune session make whatever changes are needed.

You realize that if you're handy with harness modification, it is easy to install the relay mod (to invert the 2-3 shift solenod signal, and to gate/control the TCC PWM signal).

Look into what Joe is suggesting. Plenty of guys have used an 80E with a 98 PCM.

I have to wait till November to install my Huron Speed turbo kit.....stuck in the Middle East till then. But I have a brand new in the crate "Jakes Stage 4" 4L80E that I would like to put in now. With my 1998 PCM.
In November the turbo kit goes in and I'll be upgrading to an 0411 99+ PCM.
So I am trying to NOT have to do a complete new dyno tune now with an 0411 PCM swap just because I want the transmission in now....then another full dyno tune when the turbo kit goes in.

Yup, thanks. It gets nutty sometimes. Going into Beirut on Friday for 5 days. last time I was there 2 car bombs went off in a 9 day period.....1 mile from where we were staying. Then a couple later, directly across the street from a hotel we were at....the police and military stormed a room where terrorists were making bombs. As soon as they broke the door in, they detonated it. Killed everyone and the police. We were on our way there in the car from the airport after we flew in. Had to go somewhere else for the night.

That pcm was also used on some 1998 3500 truck chassis with 454 big blocks and coil near plug ignition. IIRC they had 4l80e's in them but I doubt if if they used the same OS.
