the gasket need to order separate also?or come with filter together?
It is separate, but usually change it to assure from leaks. Although experienced mechanics do sometimes change the gasket in alternate intervals. But to be safe, always fluid + filter + gasket.

well my SC guy told me if can change every 30k.. not sure we get 5 years warranty but its mileage dependent.. besides some of us uses the car very frequently, besides we havent taken into account the way one drive. when i change my ATF oil at the milage of 20k. the ATF is already turned dark brown.. good call for me then..
Colour change is not the definite indicator. Engine oil also turn darker after 1 week fresh fill.
To give some perspective towards fully synthetic ATF, i'll reference against what i read before on Hyundai/Kia's version. The Korean's 6 speeder is also considered as "lifetime". That means, no need to change. I know someone driving with such a unit for 200k+ km, but got some weird behaviour once in a while although didn't cause the driver concern. The australian side service advice did have a special clause saying something like due to the harsher environmental conditions, the transmission fluid change interval is set at 100k km.
Although different formulations take into account, the korean 6 speeder is also fully synthetic type fluid. So, i believe the ball park number around 100k km for ATF change is sufficient; 60k if you're overly cautious; 80k for somewhere in between, which I personally target to.
