I have worked on many cars, but have never installed a transmission oil cooler. I imagine the supply lines are flexible and would be made of a synthetic material . Are the lines under a high pressure or low? Are they prone to leak? How about the outlets on the transmission, are they prominent or hard to detect. Can they be hooked up backwards? Or, flow into the cooler doesn't matter. What are the better brands, also the better materials used in their construction .All advice welcome. Thanks.
