Well it seems my TC has met it's end. I have not brought it to Chevy yet but have an appointment set for Tuesday. My logs indicated that my 1-2 shift was 0.9s and a few other shifts were 0.5s<. Car is still perfectly driveable and it only seems to slip like this at WOT. 50% throttle did not trigger the horrible shifts I am experiencing at WOT.

I am still under TM warranty so hopefully my history of bringing my car in for this problem a few times will push them to actually fix it this time.

Bit bummed out ATM. Just have to wait until Tuesday and see what they can do. I can replicate it on command. The fact that this is a pervasive issue with the A8 transmission works in my favor as well for getting this fixed under warranty.
