The Sun Coast 47RH Transmission is meticulously engineered to handle the demands of high-torque, heavy-duty applications, making it an ideal choice for towing, hauling, and vehicles with moderate modifications. Rated at 550HP, this transmission features a range of billet components and custom enhancements that significantly improve performance and reliability.

The Custom Calibrated Valve Body and recalibrated pump are key upgrades that ensure optimal line pressure and fluid volume, essential for maintaining hydraulic integrity during heavy use. The valve body is equipped with a Sun Coast-proprietary laser-cut separator plate, designed for precise fluid management, ensuring smooth and consistent shifts tailored to your specific driving needs, whether for towing, street performance, or racing.

Central to this transmission’s performance is the Pro Series Carbon Fiber Band, which offers superior friction performance and durability. This band, along with a suite of billet components—including the accumulator piston, intermediate servo, band lever, band strut, and band anchor—addresses common failure points in the factory transmission, ensuring that your vehicle can handle increased torque and stress without issue.

The 23-Spline Billet Input Shaft is a critical upgrade for those seeking to maximize their transmission’s strength. Made from 300 maraging steel and precision-ground for a perfect fit, this input shaft is heat-treated and stress-relieved, providing exceptional torsional strength and resistance to fatigue under high loads.

Complementing these features is the Sun Coast Billet Triple Disc Torque Converter, which is lined with carbon graphite clutch material and includes a precision-CNC-machined forged billet apply piston. This torque converter is designed to eliminate deflection and ensure consistent performance, even under extreme conditions.

To further enhance reliability, the transmission includes new overdrive and lockup solenoids, as well as an upgraded governor solenoid and DNJ billet solenoid housing. These components work together to provide precise control and reliable operation, making this transmission a robust choice for any high-demand application.

Backed by a 3-year unlimited mile warranty, the Sun Coast 47RH Transmission offers peace of mind along with exceptional performance, ensuring that your vehicle remains reliable and capable, no matter the challenge.
