If I swap my AWD 4L65E to a RWD version, is there anything in my 411 PCM that needs changed? Donor is a 2002 Escalade LQ9, DBW. Thanks.

PS, I would love to go 4L80E, but I believe I have the earlier 2002 Escalade OS that isn’t 4L80E segment swap friendly. If I understand correctly, to change to a later 2002 Escalade OS and calibration, I would have to pay more credits. My current OS doesn’t have a 4L80E to segment swap over. Is there a way to look at an Escalade PCM in a junk yard to know if it has the newer, more desirable OS instead of the earlier one?
