When travling this week over a mountain pass. comming down the other side we were doing about 90kmh stepped on the brakes fairly hard to slow down and the car down shifted all by itself . This would happen each time on a fairly steep angle when I applied the breaks from around 90 km or so . Even when going slower some times. Called the Toytoa dealer where we bought it new last year, and he told me this was normal with the new type Transmissions. Never noticed it before any comments on this. Checked the fluid level and seemed fine
