Next-Level Engineering for Ultimate Dependability

SunCoast's 48RE transmission is built with precision and durability in mind, featuring a custom-calibrated, lab-tested valve body for optimal shift quality and hydraulic efficiency. A high-flow 48RE filter and new thrust washers and Torrington bearings improve lubrication and longevity. Factory weaknesses have been addressed with a billet accumulator piston, billet intermediate servo, and a billet band strut, anchor, and band lever, all engineered to prevent failure and improve performance. The upgraded governor solenoid and new overdrive and lockup solenoids ensure consistent power delivery, while the 23-spline billet input shaft is heat-treated and stress-relieved to handle extreme torque loads. This transmission is a drop-in upgrade for those wanting a hassle-free, high-performance solution with easy installation and enhanced durability over stock.

Smooth, Strong, and Reliable – The Converter You Need

Paired with this transmission is SunCoast's billet triple-disc torque converter, which significantly outperforms stock. Lined with carbon-graphitic clutch material, this converter delivers exceptional holding power, reduced slippage, and improved efficiency under heavy loads or aggressive acceleration. The CNC-machined forged billet apply piston ensures zero deflection, preventing wear and maximizing longevity. Combined with a billet cover, this converter guarantees years of reliable performance, giving you smoother engagement, better power transfer, and enhanced towing capabilities. If you demand the best in durability and response, this torque converter sets a new standard in drivetrain performance.
