The way it has come on from not being noticeable to now very noticeable has me really worried that it damaged the torque converter. I haven't had any luck being out of warranty getting the dealership to perform the proper flush procedure.

I may need to look into a circle d as well, although I still guess I would need to do the flush with the proper machine and the new mobil 1 fluid anyway.

Its funny that they can engineer the fluid and converter clutches to be right on the edge of a "controlled" slip, but then once they start really slipping to where the driver can feel it, then its like they are done and you've had it.

I don't think we have access to enough parameters in HP Tuners to allow full clamp of the TC clutch during part throttle to completely stop this. However, at full throttle the TCC still seems to lockup eventually with no slippage once TCC pressure is high enough.

I'd bet money your TC is in rough shape. Tune only really works if you do it well before you experience shudder for the first time. Once you've experienced shudder, it's all downhill from there.
