I was driving my car pretty rough, and switching into third gear at about 7krpm, it seemed that it went empty and so i immediately switched to 4th to maintain speed. But when I got off the highway, the whole transmission was messed up. First and second do not work, I can get it to slide into the gear slot but it acts as if it is 5th gear. 3-5 gears seem to work. WHen the car is in neutral position, it is actually in 3rd gear. and reverse does not work either. What happened?
