I have carefully installed the product according to the manufacturer's instructions. Product Leak I carefully checked the instructions again and read them several times to see if I missed a step or made a mistake. For the sake of clarity, I am trained in hydraulic systems, pneumatics and power transmission systems, electrical and electronic systems. For the last 35 years I have serviced all my vehicles myself including Ford, Audi, BMW, Nissan and GM products. This time I have to reinstall the OEM. I would not recommend this product.
