"2012 Sorento's Transmission Need to be Taken Out for a Fluid Change!?" için yanıtThe transmission does not need to be taken out.. Absurd. Just drain and refill. I buy the Valvoline ATF fluid from Walmart for 17 bucks.. I did a drain and refill twice. There is a drain plug on bottom, refill plug on top and a level plug in the middle.. Refill until it slowly runs from the middle plug. Very easy. Transmission runs smooth. Don't let them BS you. They are there to make money..
