Check a couple things.
Is your clutch good? Is the fluid full?
Check the linkage underneath at the transmission. Make sure nothing broke, or anything.
My thought is the clutch is having an issue, but it could be the linkage.
If nothing is wrong there, then I have no idea.

i got a buddy to help me and we tore the trans apart cause the clutch was fine and the linkage on top looked fine and when we got the case off there were 4 ball bearings and a couple chunks of metal so its the tranny im just going to have to get a new one
i dont know if the ball bearings actually came from a bearing cause theyre pretty big and theres no bearing thats broken just some sheared gears but all i know is is that i need a new tranny but i wouldnt have been able to figure it out if it wasnt for my buddy me and him dropped the tranny in about an hour and a half (unorganized tools are a pain) but he got that trans completely stripped down found the problem and put it all back together in about 2 hours and hes 17 i gotta give him credit
