Just performed a complete flush and filter change on my wife's 2004 Ford Freestar. I used Walmart Mercon V to refill. The van has 186k miles, and recently had recall service done by the dealership in which it received a new torque converter. I felt the need to flush it because while the dealership performed the recall work, they only replaced what fluid was lost during the converter swap. No full flush or filter change, just five quarts of new fluid. So i ran it for awhile in hopes of clearing out any dirt or debris from the swap, then flushed it. Anyways, I have a bottle of lubegard green that has been sitting on the shelf for awhile and was wondering if it would be worth anything to dump it in. From what I understand, lubegard green is a Mercon V converter. So, am I gaining anything by adding it to Mercon V or does it contain additional lubricating value.
