Here's what happened. Car ran fine yesterday. Started up fine tonight, temp somewhere around 35F, car started fine, and backed out of a steep driveway without a problem. Into forward, and again, short uphill climb, and again, no problem. Drove about 1/2 mile to a stop sign, stopped and then pulled out.

After about 10 feet, a pop (not really loud enough for a bang) and no forward gear. Put it into reverse and it worked. Back into drive and nothing. I backed out of the middle of the street and a few hundred feet up the side road.

Just to make sure, drive again, and it seemed like it might try, but nothing. Decided to try adding a quart of transmission fluid. One quart later, still nothing.
Backed the half mile back to GF's house and parked it. Too dark and cold for a better look, but no apparent fluid on the road anywhere.

Comments and suggestions really appreciated. Once again, there was a pop, then no forward gears. Reverse seems fine. There is a slight, very slight occasional grab attempt, but nothing in drive.

HELP !!
Thanks.....
