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.
This can be due to a fault with the transmission valve body itself.I have seen valve body failure in the past before cause issues like this here needing replaced.I would have this checked/tested with the proper test equipment to be sure.
Thanks Pete
