We now turn our attention to the B&M Super Cooler transmission cooler installation. Part number 70255, the unit is rated at 9,800 BTUs of heat transfer capacity and costs only $74.95. It comes complete with the appropriately rated hose and extensive mounting hardware. Here we're scouting out a location for the cooler somewhere on the radiator core support directly in the slipstream. At the far right end of the support we found a perfect spot complete with a factory opening perfect for routing of the cooler lines. All we had to do to access the spot was to temporarily remove the horn.
