This product is designed to seal small leaks in the transmission system, potentially saving me from costly repairs.

Reading the Label and Ingredients
One of the first things I learned was the importance of reading the label. I paid close attention to the ingredients used in the stop leak product. Some contain additives that help rejuvenate seals, while others focus on thickening the fluid to stop leaks.
