The transmission may already have internal damage if it slipping but servicing the transmission would be worth trying if it is the oil that has broken down. I would change transmission oil every 30k miles. Kia as a car manufacturer put a lot of great technical information and work shop manuals on line for free for Kia owners. www.kiatechinfo.com
