Not sure if the 1517 is included, but there have been at least a couple rather recent threads on the same subject in the cub cadet discussions. So, you may be able to run a search in the CC forum and find what you need, or like Inspector507 wrote, you may have a bit quicker results posting there.
However, if I may add, it may save confusion asking a moderator to move it instead of having the duplicate post. Maybe you wanted it under Customization for some reason, else if you want it moved:
Make a reply to any of the posts [now 3] in this thread, and write something like "If this belongs in another forum like Cub Cadet, could a moderator please move it." If you need it expedited or you really blundered [certainly not the case here], then you can hit "notify moderator" on the post. From what I've seen, they are often very quick to help out.
Good luck finding the answer; can't remember if it was CC or another brand, but I remember reading about several models that can be "cured" by simply bending a little steel finger [located under the reverse postion] so it won't contact the switch. Have fun! /forums/images/graemlins/cool.gif
