Mishimoto Subaru WRX CVT Transmission Cooler
Welcome back! The quest for low transmission fluid temperatures continues. Once we developed our goals and plan of action for this project, our engineering team went to work, grinding, welding, bending, and cutting. Our first prototype design was quite unique. We mounted one of our 19-row, stacked-plate fluid coolers next to the liquid-to-liquid transfer unit. This is the same location as the turbocharger on the previous generation of EJ engines. Check out the beginning of the mock-up below!
