Welcome to the forum. Try posting your question in the Voyager and Town & Country area of the forum where your fellow Voyager owners hang out. One of them might have experienced a similar problem and may have a solution. You have posted in the "New Members" area where people introduce themselves.

When posting, include as much relevant information as you can, including year, country version, engine size and mileage, a history of the problem and what you have done to fix it. Was the garage you took it to a transmission repair shop? Transmission repair is a specialized field of knowledge not possessed by a run-of-the-mill shop.
