Was riding in 5th gear and it was like the rear end locked up. Got it home and used a 8mm wrench to get it into neutral now it will shift up and down but every gear is reverse. Reverse works perfect. But neutral is reverse also. And when I put it in first it wants to go backwards like it’s in reverse but it’s in a bind. Shift motor works fine and engine runs perfect. I just need to know if it’s something simple I’m over looking or if it’s in my transmission gears. Thanks.
