      American Powertrain Tremec T-56 Magnum Manual Transmissions and Installation Kits

      American Powertrain Tremec T-56 Magnum manual transmissions and installation kits are designed to withstand up to 700 lbs.-ft. 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 include a bolstered one-piece countershaft to resist distortion, and a stronger input shaft.

      Magnum's new synchronizers are built with 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. Nearly two dozen models are available; choose the kit recommended for your vehicle application.

      Kits include:

      Cryo-hardened steel driveshaft slip yoke with 1330 style U-joint
      Mechanical speedometer conversion
      VSS wiring harness for electronic speedometer of EFI ECU
      Reverse light wiring, weather seal harness, non-polar
      Reverse lockout wiring harness
      ISO-X ballistic, low-profile transmission mount
      Steel roller pilot bearing
      White shift knob with black 6-speed shift pattern
