Hi i have a 1963 skylark with a dual path and when i go into reverse it feels like its stuck between gears. You can actually give it some throttle (very little) and shift it into low and back down into reverse and sometimes it will unlock. Other times you can actually feel gear binding in reverse. But in neutral it rolls backwards freely. I have torn down the rear axle and determined that my problem isn't there. The gears and bearing all look great. Has anyone had this issue before?
