XDP X-TRA Cool Products has expanded into Transmission Coolers! The XD310 is a new replacement cooler for the 2006-2010 GM 6.6L Duramax 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.
