Segment Swap not available on 2 files with same OSID

I'm trying to do a segment swap after putting a 4L80E in 97 Tahoe, and have files with the same OSID (16263425). However the Segment Swap option is still greyed out. I've read the sticky for segment swaps, and I thought having the same OSID was the only limitation. Did I miss something?

Here are screenshots of the OSID, and the hpt files are attached.

As far as I know that is not a function of the vortec computers. You can use it on the LS based P01/P59+ computers.

Oh bummer. What are my options for the older vortec computers when doing a 4L80 swap? Can I just copy over all the transmission data from the 4L80 to the 4L60 or will there still be other issues?
