Suzuki Eiger won't shift
 

I have a Suzuki Eiger 400 that is an automatic. Yesterday while driving it made a loud popping noise and now it will not shift into any gear. It will start. When you do try to shift you can see the shifter move on the outside of the housing. Any ideas?

When you write "won't shift" do you mean makes grinding noises and won't go in, or goes into gear and nothing happens when you rev up? If the latter, your drive belt has broken.
