Rockland Standard Gear’s Race Division has developed a TREMEC T56 Magnum Tranzilla replacement for the 2000-2004 Ford Mustang Terminator T-56 transmission. This unit retrofits earlier models too.  Based on the TREMEC T-56 Magnum, the Magnum TZ is rated at 850 lb/ft of torque. RSG upgrades the stock unit to Tranzilla specs, with triple and double cone synchronizers and carbon fiber synchro rings for exceptionally smooth shifting. These units feature 26 spline inputs and 31 spline output shafts and are a direct fit replacement with no fabrication necessary.
