I think something is a miss then? Start with the hand control lever in neutral and set the cable position based on that. Just be aware the cable can jump out of the hole on the lever pivot if that makes sense? Once attached at the lever move down to the drive pump, the bracket near the lever (attached to drive pump) is to allow adjustment for neutral position. If you don't have enough travel or correct travel adjust back at the lever. The nut positions on the original cable will give you a good start point. Strange it should have snapped they are a tough cable, are you sure this hasn't broken something else???
