fixed the issue! The plug had moved when i was filling the trans. Just found this out when I put it on the lift. Flushed it again and moved the plug back, let out about another liter. Put new fluid back in, an extra liter too, and it seems to be driving much better now. Check engine went away too, it was the torque converter.
