A Complete Transmission System Designed For Cummins Torque Management

The ATS Stage 4 48RE Transmission Package is engineered to deliver outstanding durability and control for high-torque 4WD Cummins trucks built after May 2006. At its core is a fully built 48RE automatic transmission that features upgraded internals, clutch packs, and valve body modifications to improve holding power and shift quality. The included 5 Star Viskus Torque Converter provides low-stall characteristics and multi-disc lock-up clutches, reducing heat and maximizing torque transfer under load. Supporting this is a billet input shaft and billet flex plate, both designed to withstand high-stress use and reduce drivetrain failure during hard launches or heavy towing. The ATS CoPilot Lock-Up Controller adds intelligence by managing torque converter lock-up based on throttle position and load, allowing more precise control over drivability and heat management. An extra deep transmission pan increases fluid capacity and helps dissipate heat, especially useful for trucks that see long hauls or demanding terrain. This system is built to complement performance upgrades and is trusted by diesel tuners and towing professionals alike.
