on ebay here Item number: 220233199861 says: Lucas Transmission Fix has a polymetric film which renews worn bands to stop slipping. It cleans and lubricates sticking valves for proper shifting and controls heat and foaming. This product will extend fluid life up to three times longer. It completely stops most seal leaks and results are usually immediate. It is the perfect preventative maintenance product to stop initial wear in newer transmissions, and is a must for motor homes, towing vehicles and all other hard working transmissions. is this worth buying to sort my flare 2-3 or just a waste of time and money?
