I have a leak. Tranny or oil??

Hey, y'all. I have a small leak. I just noticed it recently. 2006, 330i, step, 84,800 miles.

Is the transmission fluid in our autos pink? This fluid isn't pink, but at 85k miles it might not be very pink anymore. Looks more like oil, but I think the consistency is lighter. I can't get a feel for what it might be from the smell. I don't think it has any burnt smell to it.

It is a little more than seepage. It is a very, very slow drip. Dripping from the underbody panel, so I can't tell exactly where it's coming from. It's dripping from the back of the panel, not the oil drain access panel.

The car has been parked for about six weeks, not driven. There is a wet spot under it. Drove it today. I'm guessing about four to eight ounces may have dripped based on the size of the spot.

The oil level reads completely full. Looked under the hood with a bright florescent light. No sign of the slightest bit of seepage at the head or anywhere else.

I'm inclined to think mechatronic sleeve. Thoughts?

I'm planning to drive 1,000 miles tomorrow and the next day to Texas. I'll be there through December, so I can have it addressed while I'm there. Thoughts on making the drive?
