Description

Converting your 1967-1968 Mustang from automatic to a modern 6-speed manual delivers the driving experience these FE-powered classics deserve. This complete conversion package centers around TREMEC's T56 Magnum double-overdrive 6-speed transmission - the aftermarket's premier manual gearbox that combines TR-6060 OEM technology with TKO-style versatility - paired with everything needed for a proper Ford FE big block installation.

The T56 Magnum withstands a massive 700 lb-ft of torque while providing remarkably crisp shifts, making it capable of handling even aggressive FE builds. The Magnum's forged gears feature substantially increased face widths and two-piece laser-beam welded construction, enabling precise shaping of engagement teeth with better pitch and angle control. Positive stops on each gear prevent over-travel on hard shifts. The robust one-piece countershaft with thicker journals and larger bearings resists distortion far better than previous T56 designs, while split-ring retainers replace traditional snap rings for superior thrust load capacity.

This package addresses the unique requirements of early Mustang FE conversions. The Ford FE bellhousing pattern (shared by 332, 352, 360, 390, 406, 410, 427, and 428 engines) requires a dedicated bellhousing to mate the Magnum to your big block. The included tunnel extension allows the Magnum's larger case to fit properly without major floor pan surgery. The hydraulic clutch system eliminates problematic mechanical linkage while delivering modern pedal feel and reliability.

MDL's guided package selection walks you through choosing the right transmission gear ratio, flywheel, clutch capacity, and supporting components for your specific engine combination and intended use. Whether building a weekend cruiser or serious performance machine, this comprehensive approach ensures all components work together optimally.
