XDP X-TRA Cool Products has expanded into Transmission Coolers! The XD309 is a new replacement cooler for the 2001-2005 trucks and features a high-efficiency core. Like our X-TRA Cool Radiators, this Trans Cooler is built using construction techniques borrowed from the HD and Semi-Truck Industry. Each cooler comes ready for installation with necessary brackets and hardware.
