With the ease of extracting more power from the Shelby GT 500, the stock T-6060 six-speed transmission will definitely need upgrading. Thankfully, Rockland Standard Gear [(800) 227-1523; www.rsgear.com] has three new T-6060 offerings to keep the power to the ground. The company has two different ratio offerings for its 850 lb-ft of torque rated transmission, and a 1,000 lb-ft of torque rated transmission for those really pushing the envelope. Rockland Standard Gear blueprints these offerings utilizing 1-2 triple-cone carbon fiber synchros, 3-4 and 5-6 double-cone carbon fiber synchros, a steel 3-4 shift fork and shift interlock, a 9310 30-spline main shaft, and heavy-duty bearings and seals.
