Are Koyorad race radiators for Manual Transmissions only?
Yes. Though many newer vehicles are equipped with external automatic transmission coolers, unless specified, all Koyo race radiators are designed for manual transmission vehicles. If you would like to use our race radiator in your automatic transmission vehicle, you will need to install an external transmission cooler. If your automatic transmission vehicle is already equipped with an external transmission cooler, and you will be using a Koyorad racing radiator, we suggest an upgrade from a reputable source.
