Something too consider for what it’s worth that I learned long ago working as a Ford line mechanic. ATF has really high detergent levels. As the fluid ages some of that detergent is broken down while at the same time band material (think clutch fiber plates) develop varnish and slightly different properties than they had when new. Reintroducing high levels of detergent into a transmission that has friction material on the bands that has aged can breakdown the varnish sand quickly destroy the bands making them slip. Toyota’s sealed “lifetime” system is a time honored approach going back to the 70s, ASSUMING you don’t seriously overheat the transmission and scorch the fluid.

When I worked for Ford our transmission expert confided in me that the only reason they sold ATF fluid replacement at a huge discount was because it sold lots of rebuilds down the road.  For what it’s worth, if you have significant miles on the vehicle and you aren’t having trans issues, leave it alone.
