My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received 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.

There are a couple of different causes I have seen myself that can cause a fault like this here.First an issue with a broken or damaged engine mount or transmission mount will cause this.If the mounts have not been checked this needs done.The other issue is a fault with the transmission valve body or debris in the valve body in some cases needing a transmission flush to remove the debris.

This will have to be checked into/tested further to locate the fault.I would start with having the mounts checked for any issues needing resolved.If these are or were checked and found to be o.k. then I would have the transmission checked into further which may require special test equipment to locate and repair this fault here.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
