What color is transmission fluid?

[sasha055]

Hi,

I have a 2000 Boxster 2.7 with manual transmission.
Lately it developed a leak that I haven't been able to diagnose (I'm not really sure what's leaking)
Every morning I see a yellow-ish wet spot (water like) in front of driver side wheel, it's not too much 20 drops or so..
Also every time I put in reverse and drive I get a cloud of white smoke coming from under driver's side wheel (like something is leaking onto exhaust)
Under the car I have fluid on left side of fuel filter and on hose that goes near spark plugs. It looks like it's coming from the top of the engine.
I changed spark plug tubes and rings, so it's not that, I'm not loosing any coolant or oil...
Since it's leaking heavily when I park in reverse I think it;s transmission fluid leaking, what color is porsche tranny fluid for manual transmssion?

Thanks
Sasha
