We stock 2 different types of transmission oil coolers: “Plate & fin” and “Thin line U-tube”. Both these coolers can be used as auxillary transmission oil coolers or as primary transmission oil coolers. The “plate & fin” construction is more suitable for street and track applications whereas the “thin line U-tube” is better suited for off-road use. These coolers are mounted directly onto the radiator or condensor core with the quick mount kit (see “Accessories”).
