The reverse is not fully engageing. Can there be adjustments that can be maid

I've seen a few times where the clamp to hold the cable sheath (At the handle end) has come loose, or clamps the cable at such an extreme angle theres no possible way to get full range of motion. Another thing is WHERE the sheath is clamped. Sometimes it's clamped too close or far away from the handle to allow full motion, this is usually due to an improper cable installed. You can also adjust the cable at the handle end, in case you didn't see that.
