2000 Toyota Corolla Car will not Move, gears dont work

Transmission problem
2000 Toyota Corolla 4 cyl Manual 88000 miles

Hi all, Today I was driving on the hw and heard a grounding noise for less then a second and then everything seemed fine. Later when I went out down the street about two miles I was in line at Mcd's and the car would not move. Nothing worked reverse, dive, low or 2nd. Had to push it to a parking spot where I shut it off. Could smell something but started her up again and I could drive it for only a couple of minutes. It did the same thing. Needless to say, I did the same thing shut it off and cool down and got to work which was only about 50 feet and left it there. I know its the transmission but how can I drive it for a bit and then it drop. Also, do you have an idea of how much this is going to cost me. The car is only 8 yrs old and has only 88000 miles on it. Thanks!
