well I was playing in the field then i went down the road came back and started up a hill and no third gear so pulled over and found out i still had 1st and 2nd is there anything that might have went bad it just went nothing at all in third still pulls the same in first and second

 

Drive to a trans shop, quickly, before you have to be towed there. Same thing happened to me. I drove around on it for a day, locally, to buy trans fluid and do a fluid/filter change. It didn't correct the problem, and by the time I made it to the shop, I lost second gear.
