Always was a Honda Accord owner, (4)... broke out and bought a 2015 Altima today with 52K miles. I loved the way it did not down shift, but maintained power- then when I got it home tonight, I see and begin to understand the drive transmission! Did more research to learn that I should change the trans oil every 25K to help prolong it's life. I'm open to any/all advise, so far 150 miles, I love the car!
