Key Features

  • 700 lb-ft torque capacity - nearly double the strength of the original T56 design
  • Dual overdrive ratios (0.74/0.50 or 0.80/0.63 depending on gear set) for reduced highway RPM and improved fuel economy
  • 135 lbs dry weight - lighter than most 4-speed automatics
  • 26-spline input shaft with 31-spline output for maximum driveline compatibility
  • Forged 4616 chromoly gears and shafts with laser-beam welded engagement teeth for precise shift quality
  • One-piece countershaft with thicker journals eliminates weak points of earlier T56 designs
  • Triple-cone synchronizers and robust double-cone synchros for smooth, low-effort shifts
  • Multiple shifter locations and dual speedometer pickups (mechanical and electronic)
  • Fully customizable package - select your gear ratio, clutch, flywheel, and hydraulic components
  • Engineered specifically for 1965-1966 Ford Mustang with Small Block Ford V8

Description

Your '65-'66 Mustang deserves more than a tired 3-speed or a slush-box automatic. MDL's complete TREMEC T56 Magnum 6-speed conversion package delivers modern supercar drivetrain technology to your classic pony car. The Magnum is the flagship of TREMEC's aftermarket lineup - an evolution of the TR-6060 found in the Dodge Viper, Challenger, and Chevrolet Camaro, purpose-built for the enthusiast market with 700 lb-ft of torque capacity and the smoothest shift action of any 6-speed manual ever produced.

The engineering behind the Magnum solves every weakness of earlier T56 designs. Gear face widths have been significantly increased to handle serious torque, with forged gears featuring two-piece laser-beam welded construction for precise tooth angles, pitch, and alignment. The one-piece countershaft - originally developed for the Viper application - eliminates the torque-limited splined connection of the old two-piece design. Inside, a robust combination of triple-cone and double-cone synchronizers delivers incredibly short, low-effort shift throws with crisp engagement. The result is a transmission that handles big-block power with sports-car refinement.

The dual overdrive configuration transforms highway cruising. Choose from multiple gear ratio sets: the wide-ratio 2.97 first gear option with 0.74/0.50 overdrives is ideal for street driving and long-distance touring, while the close-ratio 2.66 first gear set with 0.80/0.63 overdrives suits aggressive street performance and road racing. Both configurations drop highway RPMs dramatically compared to factory gearing, extending engine life and improving fuel economy without sacrificing stoplight-to-stoplight performance.

This complete conversion package includes everything needed for a professional installation: TREMEC Magnum transmission, six-speed bellhousing for Small Block Ford applications, hydraulic clutch system, crossmember, shifter assembly, driveshaft components, and all supporting hardware. Due to the Magnum's case dimensions, tunnel modifications are required - MDL provides a sheet metal tunnel extension that attaches to the OEM floor pan. The modular package design lets you configure your build exactly as needed, selecting from multiple flywheel options (steel, lightweight steel, SFI-rated aluminum), clutch configurations (single-disc and twin-disc from leading manufacturers), and shifter styles. Requires 3.66 quarts of TREMEC HP-MTF, Dexron III ATF, or GM Synchromesh fluid.
