Built for Heavy Loads, Towing, and High-Performance Driving

When it comes to towing, hauling, or adding extra power to your 2004.5-2007 Ram 5.9L Cummins, a stock transmission just won’t cut it. The SunCoast 48RE Transmission is built for reliability, durability, and high-performance driving. Rated at 450HP, this transmission is the perfect upgrade for owners who demand more from their trucks. Whether you're towing heavy loads, running performance upgrades, or simply looking for a transmission that won’t fail under pressure, SunCoast has engineered a solution that eliminates common weak points and maximizes power delivery. Say goodbye to stock transmission failures and experience smooth, crisp shifts with enhanced hydraulic integrity—no more sluggish performance or overheating issues.

Custom-Calibrated for Optimal Power Transfer

SunCoast has reinforced every critical component of this 48RE transmission to handle high torque and demanding conditions. The factory plastic accumulator piston—a common failure point—is replaced with a precision-engineered billet piston with a four-ring sealing system to eliminate leaks and maintain hydraulic integrity. The factory cast servo is upgraded to a larger billet servo for increased apply pressure, better release, and enhanced durability. The valve body and pump are custom-calibrated for higher line pressure and improved fluid volume, ensuring your transmission operates at peak efficiency. Additionally, this transmission features a carbon-graphitic pro-series band, billet band anchor, billet band strut, and billet band lever for maximum friction performance and reliability. With easy installation and a design tailored for both towing and performance, this transmission is the ultimate 48RE upgrade.

Torque Converter: The Key to Ultimate Performance

Included with this transmission is SunCoast’s billet triple-disc torque converter, engineered for unmatched power transfer and durability. The converter features carbon-graphitic clutch material for maximum friction performance and a forged billet apply piston to prevent deflection under high load conditions. This ensures better lockup, reduced slip, and more efficient torque transfer, making it a vast improvement over the stock unit. Whether you’re hauling heavy loads or looking for quicker throttle response and increased efficiency, this precision CNC-machined converter delivers. Expect long-lasting reliability, superior performance, and smoother operation in all driving conditions.
