Description

Give your '65-'66 Mustang with a Ford Modular V8 the transmission it deserves. The TREMEC Magnum is the aftermarket version of the TR-6060 found in today's factory muscle cars like the Dodge Challenger and Chevrolet Camaro, delivering 700 lb-ft of torque capacity with crisp, precise shifts. The double-overdrive design drops highway RPMs significantly compared to 4-speed automatics, improving fuel economy while maintaining strong acceleration on demand.

Engineering a Magnum into an early Mustang requires more than bolting parts together. The Magnum features substantially increased face widths on all gears, two-piece laser-beam welded gear construction, a robust combination of double and triple cone synchronizers, and enhanced webbing in the main case compared to the original T56. The redesigned shift forks feature integrated shift keys that virtually eliminate fork bending, while spring-loaded ball-type inserts reduce friction and eliminate the double-bump feel during shifts. However, the larger case dimensions demand tunnel modifications -- our included sheet metal tunnel extension integrates with your OEM floor pan for proper clearance.

This comprehensive package includes everything needed for a complete conversion. The Ford Modular bellhousing bolt pattern requires a specific bellhousing to mate the 4.6L or 5.0L Coyote engine to the Magnum. The hydraulic release system eliminates mechanical clutch linkage modifications, simplifying installation in the confined early Mustang engine bay. Choose between aluminum or steel bellhousing and hardware options based on your performance goals and budget.

Multiple gear ratio options let you tailor performance for your specific combination. Wide ratios (2.97 first gear) provide stronger launches with street tires, while close ratios (2.66 first gear) keep the engine in its powerband through more aggressive driving with smaller RPM drops between gears. Our guided package selection walks you through transmission options, clutch sizing, hydraulic components, and shifter positioning.
