Have a question & hope someone can help me out there. I bought a used Kia Rio 03 about a mo. ago and would like to give it a transmission fluid change. The manual states to use SP III fluid only. Castrol Import M/V, Valvoline Max-Life D/M, & Pennzoil M/V ATF fluids state that they meet these specs. Anyone out there know if these are safe to use or not. Thanks
