    Description

    Your '69-'70 Mustang's slushbox automatic is holding back everything your small block Ford can deliver. This comprehensive T56 Magnum conversion package solves that problem with the strongest, most versatile 6-speed aftermarket transmission TREMEC has ever produced. Based heavily on the TR-6060 architecture found in modern muscle cars like the Dodge Challenger, Viper, and Chevrolet Camaro, the Magnum combines OEM supercar technology with swap-friendly features specifically engineered for classic applications.

    The Magnum's 700 lb-ft torque capacity comes from substantially widened gear faces, two-piece laser-beam welded gear construction for precise tooth angles and pitch control, and a bolstered one-piece countershaft that resists distortion far better than previous designs. All Magnums feature 26-spline input shafts with larger input bearings and generously long splines to accommodate twin-disc clutch setups. The redesigned shift forks with integrated shift keys virtually eliminate the bending and wallowing issues that plagued original T56 transmissions under aggressive use.

    Double overdrive ratios - whether you choose the 0.74/0.50 or 0.80/0.63 configuration - dramatically reduce cruising RPM for improved highway manners and fuel efficiency. The fully reversible TKO-style die-cast aluminum shifter delivers smooth, positive shift action with incredibly short, low-effort throws. Dual speedometer pickups accommodate both mechanical and electronic setups, and built-in mid-shift provisions simplify shifter location changes if needed.

    Since the Magnum case is larger than factory transmissions, tunnel modifications are required for '69-'70 Mustang installations. This package includes a sheet metal tunnel extension that attaches to your OEM floor pan. Our guided package configurator walks you through selecting every component - from bellhousing and flywheel to hydraulic clutch system, shifter components, speedometer integration, crossmember, and driveshaft yoke - ensuring complete compatibility. MDL's concierge service provides expert guidance throughout the selection process, helping you match components to your project goals and budget.
