Description

The Suncoast Category 3 E4OD transmission is a heavy-duty unit designed for up to 450 HP. It features Alto Red Eagle clutches with Kolene steels for high friction and heat resistance, a TransGo Tugger Kit for improved shift quality and cooling, and a new solenoid pack and bushing kit. This transmission also includes a heavy-duty 45-element intermediate sprag and a carbon fiber intermediate band for enhanced heat resistance. The billet 300 maraging input shaft and billet 4140 heat-treated stress-relieved steel forward clutch drum prevent common failure points. It comes with a SunCoast Category 1 Billet Triple-Disc Torque Converter, designed for heavy-duty towing and hauling, backed by a 3-year, unlimited-mileage warranty.
