verifing segment swap

customer has a swapped c10. Has a 6.0 and 4l80 but running on an ecm from 2001 1500 yukon 5.3 4l60.

[B]I did not flash or do the trans segment swap.
[/B

Has a weird trans shifting issue. Which I believe is related to VSS not showing up. Before chasing wires I was hoping to confirm the segment swap was done right or at all. I compared file to a known good 4l80 same os file. I see some stuff different in the dtc section, and just mph shift points.

Both have a controller id number of 16264217 but CVN is different. for trans....

Is there a way to verify the segment swap was done right?Attachment 143546
