transmission wont go all way into park

And when the zip ties break (and they will break) back to square one. 3 options I see. 1. Wrap the exhaust and sheath the cable. 2. Reroute the cable. 3. Use metal to hold the cable. A piece from a spark plug wire loom perhaps, riveted to some sheet metal. Or.4. a combination of these suggestions. Regardless,zip ties near heat will break. And you wont notice until its time for a new cable......again.
