Did some more checking tonight. I found the converter pressure regulator. I pulled it out and found nothing out of the ordinary. It was clean and both springs were intact.
I took some pictures of the torque converter. Lots of stuff in the way but the torque converter regulator is right above the temp gauge for the converter on the left side of the machine. The charging pump is right below the transmission regulator. The oil for it comes out of the transmission to the charging pump to the filter then to the transmission regulator.
