Description

Converting your early Mustang from automatic to manual transforms the driving experience - adding the control, engagement, and connection that only a proper stick shift delivers. This comprehensive package centers around the proven TREMEC T5Z Super Duty transmission, the compact, lightweight 5-speed that handles up to 330 lb-ft of torque while fitting in tight first-gen Mustang engine bays without modification. At just 75 pounds dry, it is the smallest and lightest transmission in the TREMEC lineup - perfect for classic Mustangs where weight distribution and packaging matter.

The T5Z features a 2.95:1 first gear paired with a deep 0.63:1 overdrive - engineered to provide strong acceleration off the line while dramatically reducing highway RPM for improved fuel economy and a quieter cabin. This closer-ratio gearset (2.95, 1.94, 1.34, 1.00, 0.63) represents a significant upgrade over the original World Class T5, with hardened gears, steel front bearing retainer, tapered output shaft bearing, and carbon fiber 3-4 blocker rings. The offset shifter mechanism positions the gear lever precisely in the original automatic transmission tunnel opening, preserving the interior's stock appearance and ergonomics.

MDL's guided package selection walks you through every component needed for a complete conversion. Choose from aluminum or steel bellhousings, hydraulic master cylinder kits or cable clutch systems, billet steel, nodular iron, or aluminum flywheels, and street or performance clutch sets. Whether you are building a weekend cruiser or a spirited canyon carver, this modular approach lets you configure the exact combination for your power level, budget, and driving style - all with the confidence that every component has been selected for proper fitment and proven compatibility with Ford small-block 289, 302, and 351W engines.

The T5Z requires 2.75 quarts of ATF Dexron III and uses a 10-spline input shaft with 28-spline output. Complete installation hardware, speedometer components, crossmember, transmission mount, and reverse light wiring ensure nothing is overlooked in the conversion process. MDL's transmission specialists are available to provide concierge service if you need help selecting the right parts for your specific project.
