Description

Swapping your first-gen Mustang from automatic to a proper 5-speed manual opens up a world of driving engagement - but only if the conversion is engineered correctly from the start. This complete T5z package eliminates the guesswork by bundling TREMEC's Super Duty T5z transmission with every component you need for a clean, reliable auto-to-manual swap behind your Ford small block. The offset shifter design drops the lever directly into the OEM shifter hole, maintaining the stock console position without cutting sheet metal or relocating components.

The TREMEC T5z earns its reputation as the go-to transmission for classic car retrofits. At just 75 pounds dry, it's the lightest and most compact overdrive 5-speed in TREMEC's lineup - critical when you're working in a vintage engine bay never designed for modern drivetrains. But don't mistake compact for weak: the T5z's hardened gearset, double-moly construction, and carbon fiber blocker rings deliver a 330 ft-lb torque rating that handles spirited street driving without drama. The 2.95:1 first gear provides strong acceleration off the line, while the deep 0.63:1 overdrive drops highway RPM dramatically - reducing engine stress, lowering temperatures, and improving fuel economy on long cruises.

MDL's guided package selection walks you through every component choice: aluminum or steel bellhousing, clutch kit sizing, flywheel material and balance, cable or hydraulic actuation, shift knob and boot styles, even speedometer gear selection for accurate readings with your rear axle ratio. Each option has been tested for compatibility with Ford small block engines in 1967-1968 Mustang and Cougar applications. Whether you're building a weekend cruiser or a spirited canyon carver under 350 horsepower, this package delivers all the parts you need with the confidence that everything bolts together correctly.

World Class T5 transmissions require ATF Dexron III fluid (2.75 quarts capacity) - not heavy gear oil. Package includes three quarts to fill the transmission at installation. Technical support is available throughout your build.
