Description

Ditch the slushbox and transform your '67-'68 Mustang into a true driver's car with this complete TREMEC T56 Magnum 6-speed conversion package. Engineered specifically for small block Ford applications, this kit delivers everything you need to swap from automatic to one of the most capable manual transmissions ever built. The Magnum handles a massive 700 lb-ft of torque - nearly double the original T56's capacity - making it ready for anything from a mild 302 to a built stroker putting down serious power.

The T56 Magnum isn't just stronger; it shifts better too. Spring-loaded ball-type inserts replace the stamped keys found in earlier designs, reducing friction and eliminating the notchy feel that plagued original T56 transmissions. The result is incredibly short, low-effort throws with crisp, precise engagement. Triple-cone synchronizers on first through fourth gears and double-cone synchros on fifth, sixth, and reverse ensure smooth shifts even under aggressive driving. The one-piece countershaft and laser-beam welded gear construction allow for tighter tolerances and better control of tooth angles and pitch - engineering that translates directly to durability and shift quality.

Double overdrive ratios are where the Magnum really shines for street-driven classics. With a 0.50 sixth gear ratio, your small block can cruise at highway speeds while barely turning 2,000 RPM, dramatically reducing engine wear and increasing fuel economy without sacrificing the aggressive lower gearing needed for acceleration. Multiple ratio sets are available to match your rear axle gearing and driving style - the 2.97 wide-ratio first gear delivers stronger launches, while the 2.66 close-ratio keeps engine RPM in the meat of the powerband during spirited driving.

The Magnum's case dimensions require tunnel modifications for proper fitment in '67-'68 Mustangs. This package includes a sheet metal tunnel extension designed to attach directly to your OEM floor pan. Our guided selection system walks you through every component - from clutch combinations and hydraulic systems to shifters, crossmembers, and driveline components - ensuring each part is validated for your specific application. MDL's concierge service is available to help match components to your project goals and budget.
