A lot of folks had luck with the Valvoline fluid also at a low cost. It the friction modifier and anti foamant that are critical. for the pusher link belt.
The oil the dealer put in my car in a complete drain and refill was not as good as factory and it foamed a lot. I also suspect they did some reporgramming as it revved up a lot more than before the service.
The level may have been a tad high but the year of my trans has the submerged pusher belt that causes foaming. The later jatco CVT8 trans have the belt out of the sump, IIRC
BBHero. your trans as at end of life. I think you are good. Noo need to do another drain and fill.
Unless it makes you feel better.
Maybe a nice surf and turf dinner out would make you feel even better-er
