Hyundai calls for transmission fluid meeting the "SP III" spec. Are their any sources other than the dealer for this?
I was in my local O'Reilly parts store the other day, and they have Chrysler's ATF+4, from Valvoline. That used to be a dealer only fluid.
There were other fluids touting to be "universal," but I have always tried to stay with what the manufacturer calls for.
