2006 Corolla, when it's downhill and I press the brake pedal above a certain braking power, it shifts down the transmission. I was trying to figure out if that's a feature of the transmission and how does it know that the car is travelling downhill. It's probably intended for adding engine braking but sometimes it's just annoying since revs go up and it strains the engine and transmission. BTW, no down shifting when braking on a level road.
