2000 Ford Taurus Stoped Dead No Warning

The car was running fine. All of a sudden it started jerking a little. I slowed down to pull on to a side road, and the car died. IT DID NOT OVERHEAT.

There was a lot of fluid on the ground. It looked like transmission.

Replaced the battery. But car still will not turn over. It tries, but dosen't.

I was told it might be a sensor. I realize that throwing in a new engine would help, but I think the "real" problem is much smaller.

There are no apprent leaks.

Head Gasket was replaced about 15 months ago.
