Update: Learned a lot about my mistake at this point. Diff fluid fill was on other side and that has been fixed. I drained and kinda flushed the CVT. Pressurized air through the path into the radiator and refilled than ran to flush the radiator/heater outlet line. Also found out that after you have drained it and let it drip forever, and pulled the lines that go to the radiator... If you remove that plug circled in red, it instantly drops another quart+ of fluid that is stuck up in the CVT until that red circled plug is removed. Car probably has 100-200 miles on it with new fluid since this incident, and I'm not throwing any CVT codes or noticing any issues with the CVT. Gonna run it till the weekend and then drain/flush/refill again, and then just cross my fingers and hope I didn't do any serious damage that will show up later.
