Six-speed automatic — 'bulletproof,' but change the fluidminor
The seventh generation's U760E six-speed automatic is, in the words of a Toyota master tech, 'bulletproof — nothing really goes wrong with these.' The one caveat mechanics add: ignore Toyota's 'sealed for life' fluid guidance and change the fluid around every 60,000 miles, because past 100,000 the old fluid is where the rare problems start. On a test drive expect smooth shifts; a brief light-throttle shudder at 25–50 mph is the only known quirk, and it's uncommon on 2015–2017 cars.
