While i was driving the other day, i noticed a POP sound and i felt the accelerator get soft, if that makes any sense? Anyways i popped the hood and noticed the little black piece at the end of the kick down cable (NOT the actual cable but the black piece thats holding on to something, not quite sure what it's called) had snapped. I picked up a new black piece (plastic) Without a new cable and i was wondering how to replace the black piece. Any thoughts?

Thank you.
