If the dealer wonders where the update is, here is a great post.

My question is. Is there a list of updates? This tcm update doesn't seem to show up as a TSB bulletin. So it must be something different? Maybe I missed it?
04.5+ TCM. I did some searching at it seems the newer tcms are completely different. ie... the TCM is inside the tranny! WTF? Someone tried putting a newer one it and it threw a bunch of codes etc.....

The 04 and 05 5ATs I've gotten for loaners shift lightning quick and nearly instantly when you're in manumatic mode. The 05 would actually slam the 2-3 shift. I loved it. If the Atlanta guys can't help me out, I'm going to buy the TCM from an 04. The TCM is $150-200 from car-parts.com.
