So one day i was riding and my banshee just kept shifting into neutral all the time. Like right after I put it in 1st she'll jump back in N before I could even pull off. So the next day i went riding again, then its like it got stuck in a high gear because every time i go to take off it boggs down. Then i notice it wouldn't shift down. So i take it aparr and the stopper lever is just laying there. Put it back on but when i try to shift up or down, the star wont spin all the way to the next gear. Does this mean transmission is bad?
