My cluth won't go in reverse! I tried everything, from putting it into 1st or 5th than reverse, from a roll, nothing works. It literally won't go in it at all! It's like jammed from getting into it, no matter how hard I try to jam it. Is this a cluth problem or a shifter problem. The other gears seem to work fine, no popping out of gear, or slipping. It just won't go in reverse!
