Description

Transform your 1973-1979 Chevy Nova X-body with this comprehensive TREMEC T56 Magnum 6-speed conversion package engineered specifically for LS-powered builds. The T56 Magnum takes the best from TREMEC's TR-6060 OEM technologies and pairs it with the most popular features of the TKO 5-speed, delivering a transmission capable of withstanding 700 lb-ft of torque while providing incredibly crisp shifts. This is the same architecture found in factory muscle cars like the Dodge Challenger, Viper, and Chevrolet Camaro -- now available for your classic Nova.

The engineering improvements over the original T56 are substantial. Gear face widths have been significantly increased, and each speed gear features two-piece laser-beam welded construction that allows for superior tooth angle and pitch control with positive stops to prevent over-travel on hard shifts. The one-piece countershaft -- first developed for the Dodge Viper application -- eliminates the torque-limited splined two-piece design of earlier transmissions. Spring-loaded ball-type shift inserts replace the stamped keys of older designs, reducing friction and eliminating the notchy shifting that plagued previous generations.

Synchronizer technology includes triple-cone units on 1st through 4th gears and double-cone synchronizers on 5th, 6th, and reverse for smooth, high-rpm shift capability. The shift forks feature permanently mounted steel links and enhanced cross-sections for zero deflection and precision gear engagement. Split ring retainers replace traditional snap rings, offering greater thrust load capacity and tighter tolerances throughout the transmission.

Each package is fully customizable through MDL's guided selection process, allowing you to choose transmission gear ratios, bellhousing configurations (aluminum or steel), clutch systems (single or dual-disc), hydraulic components, shifters, crossmember mounting, and all supporting hardware tailored to your specific Nova build and performance goals. The dual speedometer pickup accommodates both electronic and mechanical instrumentation, ensuring compatibility with factory gauges or aftermarket setups. Fluid capacity is 4 quarts using TREMEC HP-MTF, Dexron-III, or Mobil 1 ATF.
