The SunCoast Guardian Heavy Duty (XD) line of transmissions, specifically the Category 4 variant, is engineered for extreme demands of heavy-duty towing, hauling, and work applications, capable of handling 950+ horsepower. This robust transmission features a new Suncoast V2 billet drum, which offers a 24% improvement in hydraulic clamping force over factory drums and increased friction elements in overdrive. It includes a billet 2C piston to eliminate issues with factory molded pistons and allows for an additional clutch. The SunCoast Pro-Loc Ducenti valve body ensures precise 200 psi shift calibration, removing the need for supplementary tuning. Other key components include a new OEM solenoid pack, a Zero Cavitation Filter Kit with a specially machined Mag-Hytec pan for improved fluid circulation, new 68RFE Thrust Washer and Bearing Kits, and a complete Gasket and Sealing Kit. The design prioritizes functionality, reliability, and strength for the most demanding industrial and commercial operations. The provided MPN also implies the inclusion of a converter, despite a conflicting product title on the manufacturer's site that states "no converter." Based on retailer information, this part is sold as a complete unit with a converter.
