If I read you signature correct you have a 2017 which comes with a steel pan. Mine is a 2019 and had a steel pan on it as well. Later models, not sure when they started but 2022 and later perhaps came with an aluminum pan which holds slightly more fluid. Not sure how much but more for sure. I bought an aluminum pan and had a drain bung and plug welded to the front and I also epoxied a heat sink to it to help dissipate heat. The factory procedure for filling to the right level is a royal PITA and the A10 is finicky about the level of fluid. If I had to do it all over I'd get the pan ready to install with the mods, with a new filter and gasket on hand. Then I'd carefully remove the old pan and filter and capture all the fluid to measure exactly how much came out. Then I'd also measure the difference in capacity between the pans. Now it'd be simple to install the new filter/gasket/pan and put in the same amount of fluid that came out plus the difference in pans. From here it will be a hell of a lot easier to drain and refill a few more times to flush out the old stuff.
Now that I've done mine I won't need to level the car, brake the trans to get it hot and remove the pan to change the fluid. I can now drain it and put the same amount back in and be done. You'll probably need 20 quarts to flush it completely.
I made a video which shows the pan with the mods I did to if you're interested.

Yeah I haven't gotten the chance to check the fluid level yet unfortunately. I definitely need to especially given that from the factory the level may have been problematic and I don't know the history of that level or what color it's looking like right now. As of this moment I upped the line pressure in reverse and in 7th but I haven't gotten the chance to try out the revisions yet. Hopefully the tune just needed some tweaking, otherwise the next step will definitely be transmission fluid swap out and a filter as well. I should probably buy get to buying a filter to have it on hand for when I do need to get to doing a service.
