Description

Converting your '67-'68 automatic Mustang to a proper stick-shift shouldn't mean hunting down dozens of individual parts and hoping they all work together. This complete auto-to-T5 conversion package delivers everything you need to transform your slushbox-equipped first-gen into a driver's car - with every component selected for compatibility and performance behind a Ford small-block engine.

The heart of this conversion is the TREMEC T5z Super-Duty 5-speed transmission. Don't let its compact size fool you - the T5z safely handles 330 ft-lb of torque and is suitable for street cars up to 450hp on DOT-approved tires. The 2.95:1 first gear provides strong launches, while the deep 0.63:1 overdrive fifth gear drops engine RPM on the highway, increasing fuel economy, reducing engine temperatures, and delivering a quieter in-car feel. At just 75 lbs dry, the T5 is the smallest and lightest transmission in the TREMEC lineup, fitting where others cannot - these compact, round-cased transmissions tuck right up into any '64.5-'73 Mustang with no cutting or permanent modification required.

MDL's guided package selection walks you through every component choice: select from multiple bellhousing options (aluminum or steel, various configurations), choose hydraulic or cable clutch actuation to match your preference, pick your flywheel material and balance for your specific crankshaft, and configure the complete driveline from crossmember to shifter knob. The custom offset shifter places the stick in the original automatic shifter hole, maintaining that stock appearance while delivering modern five-speed drivability. Every part in this package was developed and selected by MDL to provide the highest-level components available for your conversion.

Fits 1967-1968 Ford Mustang and Mercury Cougar with small-block Ford engines. Required fluid: 2.75 quarts ATF Dexron III. If you're uncertain about any component selection or have questions about your specific build, MDL offers concierge service to help you select the correct parts for your project and budget. Lifetime technical support included.
