Замена масла в автоматической коробке передач 6F35 на Ford Escape 2,5L 2017. Нужно ли менять?

At 88,000 km, I decided to change the transmission fluid in the 6F35 automatic transmission. This is Ford's simplest and most reliable torque converter. However, the manufacturer claims it doesn't need changing and is designed to last the entire life of the vehicle. Is this true? Let's see. Recently, the gear shifting has become slightly rough. But after a partial change, the transmission has become noticeably smoother. I'll change it again in 3,000 km. Definitely!
