ive been reading in an effort to do the right thing maintenance wise on my x. it seems that there are a few diferences between the x and the 250's-350's. does any one know of a listing with some of these diferences or is it possible to somehow start a running list. the reason i ask is i am preparing to do my transmission flush and have been reading as much as possible but i have a feeling that the x does not come from the factory with the in line transmision filter. does any one know the answer. thanks
