    Could be leaking at the turbo/turbo line or the plastic flange on the back of the head just above the transmission. If your losing fluid that fast the leak should be obvious where it's at. Is it leaking while it's just sitting cold?
    Also check the hose to the radiator and the radiatior drain plug

    I should have specified, my fault, my j-plug was leaking and the coolant was finding hoses and any route it could and was "appearing" to be leaking from the passenger side. I had puddles under the passenger side for a week and I tried everything I could to find it. It ended up being the j-plug and I could see the path it traveled over different hoses. Now I'm not saying that's what it is for sure, but something to look into if you can't seem to find the source of the leak.
