Trans question on an '07 TBSS Tq Management section

Where would I find info on the TQ reduction patterns? Specifically what they are, and how the trans tables get used. There's a lot of things in the trans section of my tune, that don't make sense to me. I come from the old LT1 days and this stuff is all Greek to me....lol

I did some trans tuning in my 2000 Regal GS, but like you, this TBSS is pretty greek to me as well.
