First trans fluid change at 120k miles?

I just bought a 2012 hatchback with auto transmission. No maintence records. The "CareCarNut" on youtube, who seems to be knowledgeable, recommends that if:redface: a Yaris has over 100,000 miles and has never had that trans fluid changed, NOT to change the fluid.

I doubt mine has ever been changed and I don't seem to have any shifting issues. No burn smell on the trans lipstick.

So, do you concur that it is better to let a sleeping trans lie and NOT change the tranny fluid on my little Yaris?

I changed mine for the first time at around that mileage and no issues at all.I did change it again after another 100K miles and now it has 267K miles on it and no issues.Car care nut didn't have Yaris in mind when he said that,watch his Yaris video.This automatic transmission is solid.

My trusted mechanic says he doesn't recommend doing it.
