what he said, i don't believe the is a recommended service interval for the fluid? correct me if i am wrong. But until it has some mileage on it, then you start checking the color, looking for burn etc. Unless you are terrible to the tranny or there is something else wrong with it, i don't see any reason it should need changed. (maybe a long life change every 100k or something?) Other than an attempted upgrade, but if it already has synthetic in it, you wont see a performance change. VW owners like putting gm syncromesh in their trannys for an improvement, i imagine being this car is a GM that it has that, or its korean equivalent.
changing the tranny fluid with every oil change is about as wasteful as the government overseeing BP fixing an oil spill.
