Pulled the transmission out and yanked it apart today. As I suspected the friction plates were toast. I haven't seen anything else out of place. I put most the trans back together using the friction plates and steels I pulled out of the transmission when I first rebuilt it back in February or so. I haven't put the valve body back on it yet, as I want to make sure it's cleaned out for sure.
The plates I pulled out of it on the left and the "old" ones I'm re-installing on the right. In another stack the friction plates looked cooked and the steels had hot spots. I believe this to be the result from when my TCC solenoid came loose and about fell out. I'm guessing hydraulic pressure dropped dramatically.
