My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
My info is limited on your model here but I see no one else has responded and thought I would see if I can help here.
If you hear any clunking or grinding when trying to shift into reverse this can indicate a mechanical fault in the transmission itself usually.In this case the transmission would need inspected for repair to locate and correct this issue.The best for this to be done of course is a dealer as they usually have the best test equipment and experience to do this testing.If this is not an option to have this tested by a dealer or authorized repair center let me know.
If they have a bulletin most likely it fits what is occuring here and they should be able to repair this with ease from the bulletin.In some cases depending on the bulletin they may repair this at no charge to you.
If you need anything else let me know and feel free to rate my help if you like.
