This photo shows the transmission cooler in place in the slipstream, done in conjunction with a custom radiator conversion. Generally, such a cooler installation is spliced into the existing transmission cooling lines downstream of the factory heat exchanger located inside the radiator. We've seen both sanitary hard line installations as well as those done with rubber hose. When using rubber hose, however, be sure you are buying hose rated for transmission fluid, as regular fuel or coolant hose will swell and get soft when used for oil lines. We also recommend stainless hose clamps (non worm drive) that will not cut into the hose when tightened.
