I was backing the lift out of my shop slowly I might add and had to switch hands on the steering wheel and in doing so I hit the transmission lever into forward. I immediately knew I had screwed up because when I shifted back to reverse it felt like it was dragging. In reverse you have to give it a lot of throttle to make it move and when it does it kinda jerks back and drags but will move. When you place in neutral it tries to move forward and in forward it moves fine. Linkage all appears good to me. Any ideas??
