What is your question?
My 2003 Seville STS, VIN 9, needs new transmission. Can I replace it with one from 2003 SLS or DeVille? Will one from cars model year 200-2002 work? If not, can I swap transmission AND computer wit SLS model? I don't care about loosing some performance, I just need to repair it for less.

Both these transmission takes a 4T80-E the difference if you have a VIN 9 the difference is there is VIN Y so there is a difference and it is not interchangeable, you need to go by the VIN
I understand that there is a difference, but what exactly is it? If I put transmissions from Seville SLS (VIN Y) and change car's computer - also from SLS, it should works, right? Or not? And if not, why not?
