Here you can see the new Magnum next to a traditional T-56. The two main differences are the overall length (about 28.3 inches) and the shifter placement. While the case of the Magnum appears similar to the original T-56 in many respects, the main case and endplate of the Magnum have also undergone extensive modifications in order to safely handle extreme power loads from their intended applications. Throughout the transmission, material has been strategically placed to prevent leaks under high-stress conditions and increase overall power handling capabilities. This increased strength added a few pounds to the transmission, which comes in right around 130 pounds.
