Little more of an update, looked over the parts a little bit closer and found severe damage to the pump wear plate. All of the seals (sealing rings on stator support and all soft seals) look good/not torn or damaged. Reference the YouTube video for reference on how the truck was shifting, it was mainly an issue on the 3->4 and 4->5 shift.

I think it happened one of two ways:
1) It hurt the C2 during DPC 2019 based on the way it shifted once the converter was locked under full power (1/4mi passes). I then think when it tried to grab 4th gear sled pulling it fully killed the C2. The truck did try to downshift to 3rd which I think then warped the C1. I believe this is what happened as the truck was able to drive off the track in a 3rd gear start tune but not in any other gear (no reverse etc). I then think once I tried to pull it off the trailer it filled the filter and ran the pump dry/low causing that massive wear scar on the wear plate.

2) It hurt the pump and sent debris into the trans causing a valve to stick and burn up the C2 overloading the C1.
I am not saying the above is what happened, I am just brainstorming what may have caused the failure is all so if anyone has any ideas PLEASE don't be afraid to comment. I personally think the C2 got hurt during DPC as a culmination of the transgo lockup valve, only a single shim (not the biggest offender), and the transgo hard part mods taking out any of the cushioning. After talking with those more knowledgeable (Evan) I will be trying to source a set of Carbonite C1, putting G2 into the C2, and re-using my good Carbonite C3 and C4 assemblies (frictions measure 0.081" to 0.084", no heat spots on steels etc).
