I was given a trans cooler when I brought my car a few years ago. My question has two parts. Is it still safe to use after sitting in a closet all this time and what else do I need to make it work. I do not have the instructions and was told by the previous owner that it had been on the car before. I am trying to include a pic. I am getting a vigilante tc installed next week and thinking about asking the shop to install it if I have all the pieces.
