Is the Check Engine Light on if so retrieve codes stored in the computer of your car that would then indicate where the problem is. It does sound like it is a transmission problem. 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
