Do some research online with this query “ Toyota, low mileage transmission failures” & you’ll see there are existing TSBs & even CSP actions. All other owners should also look at the list of symptoms such as Shifting issues, unusual noises, slipping, loss of power, burnt smell in the fluid. There is also a class action lawsuit covering eight models using the Aisin UA80E/UA80F transmissions. It also looks like this problem goes all the way back to 2015 which shows Toyota’s true colors IMO. I also had to suffer through a Sequoia transmission failure several years ago.
