Product Description

American Powertrain Tremec T-56 Magnum manual transmissions and installation kits are designed to withstand up to 700 ft.-lbs. of torque. Their gears feature substantially increased face widths and 2-piece laser-beam welded construction, allowing for greater control of the tooth angles, pitch, and alignment. The transmissions also feature a bolstered one-piece countershaft to resist distortion, and a stronger input shaft. Their new synchronizers feature fine tooth angles, redesigned shift forks, and an extensively modified transmission case to prevent leaks under high-stress conditions and increase overall power-handling capabilities.

* Rolled tapered steel transmission tunnel patch
