Torque Converter or Steering Rack Line Leak?

Torque Converter or Steering Rack Line Leak?
2006 Cayenne S Titanium Edition with 162,000 miles.
I noticed fluid on my driveway so when I put my Cayenne up on my four-post lift, this is what I found. It appears to be transmission fluid leaking from between the engine bell housing and the transmission. However, the top power steering line appears to be soaked. I think it's a case of the leak from the transmission leaking down onto the rack line and not the rack line spraying it up onto the bell housing. Any thoughts on what is the source of this leak? Thanks.

Mine does the exact same thing. Try plugging that small threaded hole in your top photo that you can see just above the rack. If it stops that suggest it is coming from the bell housing area. I actually put a hose in mine to collect the fluid to see what it was. When the coolant pipes under the intake manifold leak or burst they pour coolant onto the torque converter seal, eventually hardening it and causing it to leak. So depending on the history, that could be a slow leak from a coolant line dripping down into that area (because it does look watery), or a bit of a leak of tranny fluid in the same area, or a combination of both.

Did anyone discover the leak source?
I just got back from a 4800 mile trip towing a Airstream (2008 Cayenne S) and after sitting for a few days I had a puddle of fluid under the car. Clear, oily, no odor.
Appears to be dripping from bellhousing.
Power steering fluid low, however boots and rack are dry.
Check coolant light came on too.
