Please help. I’m a novice at repairing ATV’s. I removed the bevel gear cover to replace the leaky gasket. Took off motor mounts and exhaust, moved motor forward, took off bevel gear, put on new gasket, and put everything back. Now, I can’t put it in reverse. The lockout cable works like it should and I get the green neutral light. I put in neutral, turn the reverse switch, and push down on the shifter and feel no resistance at all on the shifter like I used to. . Any idea of what I may have screwed up?
