Answer
Hello and thanks for the question...I'll try to help.
 There aren't many things that will cause what you are talking about. I would strongly suggest you bring it to a transmission shop and have them look at it.  I think you'll find that you will need a rebuild for the unit.
Hope this helps,
Erik
