I heard too much scary stories about trying to *drain and refresh* the transmission oil on this type vehicles. 1st of all, it says: *Lifetime warranty* So if I were you, I wouldn't even mess with it; because the way people talk about it, it's a very sensitive system to not even mess with. So maybe i'm wrong....Otherwise I'd love changing mine too, as it feels a little harder to push from: P to D
