Thanks Lextech!
He got lucky that as it's same OS as his so the tranny segmant swap does work. He won't need a full flash.
IIRC all Vortec .tun come up with blank VIn? Just looked at a couple I have and all VIN say N/A.

I haven't looked at a 96-2000 GMT400 tune in so long that I didn't remember that.

Go on, I thought a trans segment swap dictated a full flash. Can you give me the version for idiots? Because I test drove the truck today and 2nd and reverse work great.
Do I highlight the transmission tune segment, click "copy entire segment", then simply right click the transmission tune segment on my truck's tune and paste and do a normal reflash?

Open your .tun in EFI Live.
File, Load Alternate for Comparison.
Edit, Copy entire Segment, choose Transmission, Yes, OK. Save file with new name.
Flash into your truck.
Just a normal flash? This sounds too easy, I just got hella lucky didn't I. . .

Yup, the calibration part only. Vortec won't do a full flash with OS. Can'r segment swap unless OS matches. Luck was Lextech had a 4L80E trans segment with your OS... or you would be
Hmm, I was under the impression that you could only segment swap if you had your desired transmission in the same OS as your original calibration and that that required a full flash to accomplish the segment swap. So you're saying that's not the case? Only a full flash is required for a segment swap if you steal your trans from a different OS? Either way, a normal flash is easily undoable. Now I wish I'd parked my truck outside the shop yesterday as it's locked inside. I got the truck all put together yesterday, unplugged the trans, and 2nd and reverse work as advertised. I'm ready for the rest of it now.

I hope I did not steer you in the wrong direction or get your hopes up?
When I found the limitations I just stopped using EFI Live for the Vortec.
Tell ya what... if I got your hopes up and does not work? Mail me the PCM and I'll full flash it for ya!
Well I haven't tried it yet, so it should or shouldn't work then?

Segment swap works, I already did that. Got nothing to test the flash on?
