Hello, welcome. My name isXXXXX will do my very best to
assist you with your question.

This is likely a internal failure to the gear box and from what you are describing this is the valve body that is causing this issue.The valve bodys are known to fail on these vehicles and this would be a expensive repair.The only way to test this is to have the vehicle connected to a diagnostic tool and test driven.
