Ted.
I've had the 3 flushes done when the car was at 2000 miles. The Dealer said any more issues and they would replace the torque converter for me. It's only 4-5th gear that I notice this and what has me questioning is the fact that I see "Torque Management Advance" kicking in like normal on the shift, but then it stays active for a second after the shift. On the shift it pulls the normal 20ish degrees, but then 4-5 it falls back down to 7-10 degrees of Torque Management Advance and I can feel the power loss in the start of 5th.

I'm going to end up taking it in to the dealer soon just to have the converter replaced. But I still wanted to see if this TMA thing was normal or not. I assume the ECU is activating it past the shift point due to the laggy shift.
