That was my suggestion, too...check selector shaft for leaks. It can leak past the shaft seal, and run forward, and drip off the front of the trans. The seal is replaceable in the car.

Thanks, Joel.

I just checked around the selector shaft.  It seemed dry to me.  But it is wet at the front of the fluid pan.  But I have changed that gasket already. (?)

The pan may well be leaking, regardless of changing the gasket before.
Have you checked to see if the pan bolts are loose?
What kind of gasket did you use, cork, paper, etc?
You say the trans has had the front seal replaced, but was the pump resealed at the same time? There is an o-ring around the outside of the pump that can leak, as well as the bolts that hold the pump to the case. IF you are 100% certain the leak is NOT coming from the pan, I would suggest removing the dust cover, and looking to see if the leak is coming from the pump area. Normally, a front pump seal leak will show more on the passenger side, since the fluid gets slung over to that side with the engine running. A leak around the pump o-ring will simply run straight down, and then run along the edge of the pan.
I hope it's just the pan gasket leaking.

I drove about 10 miles to get it warmed-up and then I let it sit for more than 5 minutes with the engine running.  No leak.  But when I turn the engine off and let it sit for a while, that's when I get the leak.

Best suggestion I have is to clean the area really well(brake cleaner works nice), and drive it again.  Then get it up in the air(if possible) and see if you can locate the source of the leak. The front driver side only has the shifter seal, or the pan, that could be leaking, unless it is actually leaking from the front pump area....

I finally got the car up on a rack and checked the selector shaft.  It definitely was leaking around that seal.  The seal is now replaced and we're going to take the car out for a drive, bring her back in, let it sit overnight and check it again in the morning.  I'm keeping my fingers crossed.  I'll check back when I know if it's fixed or not.  Regardless, thanks for the tips guys.  I appreciate it.

Hope that takes care of it!
