I have a semi-automatic Quadsport that runs fine, shifts through all gears, but I can’t get the reverse to work. I put it into neutral and try to push the lever, down by the chain, back but it won’t budge. I’ve even given it some love with a 10lbs. hammer but I don’t want to hit it too hard and mess up the transmission or something. I can’t find any forums about this issue so anything you guys think might work would be appreciated. Thanks.
