Kia seems to think that I should take it to the dealership, but...

How do I get the transmission fluid/gear oil into the transmission of an '08 Kia Spectra5? It's a manual 5-speed, and, as far as I can tell, there is no dipstick. I feel like there should be an answer somewhere in a kia-specific forum (e.g. http://www.kia-forums.com/), but I can't find it. Google is clogged up with auto parts dealers trying to sell me crap, and the local auto parts stores don't have a service manual I can check.
