Your vehicle does not have a filter, or at least it's not changeable.

I believe you have a sealed system, which means you cannot service it. Do you have a tranny fluid dipstick?

Filter may or may not be serviceable, but I doubt the fluid is a sealed system. May have to go to the dealer to get a trans pan gasket, then remove the pan to drain the fluid. To be sure look in your owners manual at the transmission service interval, I bet it is around 7500 miles. In the old days transmissions did not have drain plugs on them, only way to service was to drop the pan, did not matter because you were going to ghange filter any how.

There is a drain plug. I cant find any pictures, but its there. If I remember correctly the plug looks like a regular bolt. It is either a 17mm or 19mm wrench size. Look on the lowest point of the transmission near the back for the plug. It isnt going to hurt anything if you remove a bolt and find out its not the right one. Just replace it and try again. It should be obvious once you find it. I cant seem to find any pictures to help you.
You dont have to remove the pan at any time for this service.
The service interval is every 30k.
Hope this helps ya,
Billy

Billy, 30K on trans service? Kia has more faith in their fluid than I do, no way I would go past 10k.

30k is the manufacturer recommended interval. The fluid has NEVER been a problem with the Kia or Hyundai transmissions. The fluid will get dark around 20k, but is still plenty useful until 30k. I have seen some go 40-50k without even getting dark, but then I have seen some only go 10k and its black like crude. There has never been an issue that I know of with the fluid, Only the transmissions themselves. Kia and Hyundai do not train their techs to rebuild their transmissions. If there is a problem they replace the unit. They arent allowed to go inside the units so we will never really know what goes on inside them when they go bad.
